COVID-19: Trial to find the best gap between vaccine doses for pregnant women
Scientists will study the best gap between coronavirus vaccine doses for pregnant women in a bid to increase confidence in the jabs. More than 600 pregnant women will be recruited for the trial which will see the vaccine's effectiveness monitored, along with the child's development to the age of one. Scientists hope the study will reassure pregnant women about the safety of the jab, less than a week after research revealed that most pregnant women admitted to hospital with COVID-19 have not been vaccinated.

Delta infections among vaccinated likely contagious; Lambda variant shows vaccine resistance in lab
Among people infected by the Delta variant of the coronavirus, fully vaccinated people with "breakthrough" infections may be just as likely as unvaccinated people to spread the virus to others, new research suggests. The Lambda variant of the coronavirus, first identified in Peru and now spreading in South America, is highly infectious and more resistant to vaccines than the original version of the virus the emerged from Wuhan, China, Japanese researchers have found.

AAP urges post-COVID-19 follow-up to monitor for residual symptoms
New AAP interim guidance on post-COVID-19 conditions in children and adolescents recommends all patients who test positive for SARS-CoV-2 infection have at least one follow-up conversation or visit with their pediatrician to discuss residual symptoms, explore new symptoms and guide their return to activities. More than 4 million U.S. children have tested positive for SARS-CoV-2. Although acute illness may be less severe in children and adolescents than adults, severity does not predict subsequent or ongoing symptoms. According to the guidance, “COVID-19 can lead to many secondary conditions, which can range from subacute to severe. Long-term effects from SARS-CoV-2 infection may be significant, regardless of the initial disease severity.”

Study: Severe COVID, higher viral loads, immune response linked to obesity
Among US Military Health System (MHS) beneficiaries diagnosed as having COVID-19, obesity was independently and strongly associated with hospitalization, need for oxygen therapy, higher viral load, and an altered immune response, according to a prospective study late last week in the Journal of Infectious Diseases. A team led by researchers from the Uniformed Services University of the Health Sciences in Bethesda, Maryland, used logistic regression models to compare the viral loads and immune responses in obese and non-obese patients at seven military treatment sites, stratified by hospitalization. Patients were included if they had confirmed or suspected COVID-19 or had a recent high-risk exposure to the virus.

With expanded FDA nod, Regeneron's COVID-19 antibody drug can help the immunocompromised
With its rapid mutations, the evolutionary process of the coronavirus makes it a moving target. And so it is with treatments for the disease, which can quickly become in vogue or obsolete. Case in point for the former: Regeneron’s antibody cocktail REGEN-COV. Over the last few months, nearly every development in the COVID-19 antibody market has broken in favor of the treatment, a combination of casirivimab and imdevimab. On Friday, the FDA granted emergency use authorization to REGEN-COV as a preventative measure for those who have been exposed to COVID-19 and who are at high risk to progress to a severe case because they are not fully vaccinated or are not expected to mount an adequate antibody response to vaccination.

CDC study shows three-fourths of people infected in Massachusetts coronavirus outbreak were vaccinated but few required hospitalization
A sobering scientific analysis published Friday found that three-quarters of the people infected during an explosive coronavirus outbreak fueled by the delta variant were fully vaccinated. The report on the Massachusetts cases, from the Centers for Disease Control and Prevention, offers key evidence bolstering the hypothesis that vaccinated people can spread the more transmissible variant and may be a factor in the summer surge of infections. The data, detailed in the CDC’s Morbidity and Mortality Weekly Report, helped persuade agency scientists to reverse recommendations on mask-wearing and advise that vaccinated individuals wear masks in indoor public settings in some circumstances.

'War has changed', CDC says, calling for new response to Delta variant
The war against COVID-19 has changed because of the highly contagious Delta variant, the U.S. Centers for Disease Control said, proposing a clearer message, mandatory vaccines for health workers and a return to universal masking. An internal CDC document said the variant, first detected in India and now dominant across the globe, is as contagious as chickenpox and far more contagious than the common cold or flu. It can be passed on even by vaccinated people, and may cause more serious disease than earlier coronavirus strains. The document, entitled “Improving communications around vaccine breakthrough and vaccine effectiveness”, said the variant required a new approach to help the public understand the danger - including making clear that unvaccinated people were more than 10 times more likely than those who are vaccinated to become seriously ill or die.

Pregnant women urged to get Covid jab amid rise in hospital admissions
England’s top midwife is urging expectant mums to get the Covid-19 vaccine as soon as possible, as new data suggests a worrying rise in Covid-19 hospital admissions among unvaccinated pregnant women in the UK. There is also evidence that the Delta variant poses a significantly greater risk to pregnant women than previous strains. The data suggests that the overwhelming majority (98%) of 171 pregnant women hospitalised with coronavirus symptoms since mid-May had not received a Covid-19 vaccine, compared to just three women who had received a first dose, and no fully vaccinated pregnant women.

No increased risk of blood clots after second AstraZeneca coronavirus vaccine
A recent study has found that there is no increased risk of developing blood clots after receiving a second dose of AstraZeneca’s coronavirus vaccine and that the rates were comparable to those in healthy, unvaccinated people. AstraZeneca’s coronavirus vaccine received a lot of negative attention in April due to blood clots being reported following a first shot, resulting in many governments temporarily putting a stop to administering it, and later setting a minimum age limit to minimise the risk of fatal side effects.

Efficacy of Pfizer/BioNTech Covid vaccine slips to 84% after six months, data show
The efficacy of the Covid-19 vaccine developed by Pfizer and BioNTech fell from 96% to 84% over six months, according to data released Wednesday, a decline that could fuel Pfizer’s case that a third dose will eventually be required. The data, released in a preprint that has not been reviewed by outside scientists, suggest the vaccine was 91% effective overall at preventing Covid-19 over the course of six months. In the ongoing study, which enrolled more than 44,000 volunteers, the vaccine’s efficacy in preventing any Covid-19 infection that causes even minor symptoms appeared to decline by an average of 6% every two months after administration. It peaked at more than 96% within two months of vaccination and slipped to 84% after six months.

EU needs more than 70% vaccination coverage to stop variants, warns Belgian virologist
The European Union needs a vaccination coverage higher than 70% of adult population to stop the spread of new and highly transmissible COVID-19 variants, says Belgian virologist Marc Van Ranst, warning the virus can "happily circulate" among the unvaccinated. "We have to reach a vaccination level that is higher than 70%, that is clear," Ranst told Euronews. "Against the original variant, the one that came from Wuhan, probably 70% would cut it. But then the British variant came, and then the Indian variant came, and they were much more infectious, which means you need a higher vaccination coverage to sort of counter this."

Transplant patients' higher rate of COVID-19 breakthroughs boosts case for booster vaccines
Transplant physicians have worried for months that their patients might not be getting the protection they need from COVID-19 vaccines. Studies have already shown that many organ recipients don’t produce coronavirus-fighting antibodies even after two doses of the highly effective messenger RNA (mRNA) vaccines—an indication their bodies are unable to mount a strong defense against SARS-CoV-2. A study out today indicates this lack of antibodies is indeed translating to a much higher risk of “breakthrough” cases of COVID-19 among vaccinated transplant recipients.

Israel: Pfizer vaccine allows infection but prevents severe illness
A new study released this week from Israel’s Health Ministry found that while the Pfizer-BioNTech vaccine is highly effective at preventing severe COVID-19 cases caused by the delta variant, it was much less effective than the health agency previously thought at protecting people from infection. The study, conducted from June 20 to July 17, found that the two-dose Pfizer-BioNTech inoculation was roughly 88 percent effective at preventing hospitalization due to the delta variant and about 91 percent effective at protecting against severe cases. However, the Israeli health agency said that for symptomatic COVID-19 cases, the vaccine was found to offer just about 41 percent protection against the delta variant, with an overall effectiveness of 39 percent for preventing delta variant infections.

Eight-week gap between first and second Pfizer vaccine doses ‘a sweet spot’
An eight-week gap between the first and second doses of the Pfizer/BioNTech Covid-19 vaccine is a “sweet spot” when it comes to generating a strong immune response while protecting the UK population against the Delta variant of coronavirus, scientists have said. In a new study, funded by the Department of Health and Social Care (DHSC), researchers have found that when compared to a four-week gap, a 10-week interval between the doses produces higher antibody levels, as well as a higher proportion of a group of infection-fighting cells in the body known as “helper” T cells. However, when all the "pros and cons" are taken into consideration - such as soaring cases of the Delta variant and society opening up - eight weeks is the optimum interval.

UK scientists back Covid boosters as study finds post-jab falls in antibodies
Scientists have backed proposals for Covid boosters in the autumn after blood tests on hundreds of people revealed that protective antibodies can wane substantially within weeks of second vaccine shots being given. Falls in antibodies after vaccination are expected and do not necessarily mean people are more vulnerable to disease, but the researchers are concerned that if the declines persist the effectiveness of the vaccines may diminish. The UCL Virus Watch study found that antibodies generated by two doses of the Oxford/AstraZeneca and Pfizer/BioNTech vaccines started to wane as early as six weeks after the second shot, in some cases falling more than 50% over 10 weeks.

India’s fourth national sero-survey, which examines the prevalence of Covid-19 antibodies either through infection or vaccination, found that 67.6% of the population of more than 1.3 billion has coronavirus antibodies. The survey also demonstrated the slow pace of India’s vaccination programme. Of those surveyed, 62.2% had not been vaccinated, 24.8% had taken one dose and 13% were fully vaccinated. The survey result marks a significant rise from the last such survey which was conducted in December and January and found that just 24% of the population had antibodies

COVID-19 variants develop better lock-picking skills to invade human cells
Like expert lock pickers, COVID-19 variants may be more adept at breaking into and infecting human cells, according to new research conducted by FIU physicists. The variants are able to do this by flexing a spike protein that works like a lock pick, unlocking and slipping into a cell for infection. The better the virus can manipulate the spike protein, the easier time it has accessing the cell and eventually spreading in an unvaccinated population.

J.&J. Vaccine May Be Less Effective Against Delta, Study Suggests
The coronavirus vaccine made by Johnson & Johnson is much less effective against the Delta and Lambda variants than against the original virus, according to a new study posted online on Tuesday. Although troubling, the findings result from experiments conducted with blood samples in a laboratory, and may not reflect the vaccine’s performance in the real world. But the conclusions add to evidence that the 13 million people inoculated with the J.&J. vaccine may need to receive a second dose — ideally of one of the mRNA vaccines made by Pfizer-BioNTech or Moderna, the authors said. The conclusions are at odds with those from smaller studies published by Johnson & Johnson earlier this month suggesting that a single dose of the vaccine is effective against the variant even eight months after inoculation.

Covid-19 vaccines are safe for children but regulators say benefits may not outweigh the tiny risks of harm
In the UK, the Pfizer vaccine is already approved for use on anyone aged 12 or over, having been signed off by the Medicines and Healthcare Products Regulatory Agency (MHRA). That decision was based on analysis of safety data and the experience of other countries which have already started administering vaccines to the under-18s. It shows that the experts believe it is not inherently unsafe to give the jab to teenagers. But the decision by the Joint Committee on Vaccination and Immunisation (JCVI), which determines the strategy used to give jabs in the UK, not to roll out the vaccine to most children this summer is based not just on the safety of the vaccine but on the cost-benefit ratio for any given individual.

Lockdowns not more harmful to health than COVID-19: researchers
Lockdowns are not more harmful to health than COVID-19, according to a commentary published Tuesday. In a commentary published in the journal BMJ Global Health, researchers evaluated evidence to examine whether government interventions such as lockdowns led to negative health consequence. "The fact that there are no locations anywhere in the world where a lockdown without large numbers of COVID-19 cases was associated with large numbers of excess deaths shows quite convincingly that the interventions themselves cannot be worse than large COVID-19 outbreaks, at least in the short term," the researchers wrote.

Vulnerable UK children to be offered Covid jabs first, minister says
Children in the UK will get a Covid vaccine only if they are over 12 and extremely vulnerable, or live with someone at risk, as scientists raised concerns about inflammation around the heart linked to the Pfizer jab. Sajid Javid, the health secretary, said he accepted the advice of scientific advisers that only children over 12 with severe neuro-disabilities, Down’s syndrome, immunosuppression and multiple or severe learning disabilities should be allowed to get the Pfizer vaccine. Children over 12 who live in the same house as people who are immunosuppressed will also be eligible for jabs. The opinion of the Joint Committee on Vaccination and Immunisation (JCVI) expands the eligibility for children, after a previous decision that vulnerable 16- and 17-year-olds could get vaccinated.

Dr Anthony Fauci said the new guidelines are 'a reasonable thing to do' due to vaccines not being approved for children under age 12. In the recommendations, the AAP said masks should be coupled with regular testing, promoting hand hygiene and contact tracing

Heart medications may not affect COVID-19 outcomes
People with cardiovascular disease have a higher risk of poor outcomes from COVID-19, but the interaction between cardiovascular medications and COVID-19 is unclear. Analyzing hundreds of observational and research studies, scientists found that cardiovascular drugs do not affect COVID-19 outcomes. The results indicate that people at risk of or with COVID-19 should continue taking cardiovascular medications as prescribed. The researchers plan to continue to build their evidence base as new studies are published, creating a “living” systematic review.

Long COVID-19 unlikely among fully vaccinated, physicians say
If a person is fully vaccinated and develops a breakthrough COVID-19 infection, early trends indicate it's unlikely they'll experience long-haul symptoms, NBC News reported July 15. While it's possible and more research is needed, some physicians working at post-COVID-19 clinics say they haven't seen demand from patients who've been fully vaccinated. At Rochester, Minn.-based Mayo Clinic's post-COVID-19 program, it's been "quite rare," Greg Vanichkachorn, MD, an occupational therapist who works with long-hauler patients, told NBC. Although anecdotal reports, physicians leading such clinics at Tulane University in New Orleans and Washington University in St. Louis haven't seen patients come in after a breakthrough infection either. Additionally, early research hasn't indicated there's a significant risk.

Hand and contact surface hygiene is still essential to keep Covid-19 at bay
While Covid-19 is primarily an airborne pathogen (Hygiene theatre: how excessive cleaning gives us a false sense of security, 12 July), transmission via hands in combination with surfaces recently and frequently touched by other people remains a secondary but real danger, as the World Health Organization, the NHS and the Centers for Disease Control acknowledge. The need for an integrated approach (social distancing, ventilation, face coverings, hands and hand-contact surfaces) for controlling Covid-19 was reiterated in a 6 July government review. While “hygiene theatre”, particularly spraying of surfaces in public spaces, is largely irrelevant, bracketing this alongside – and thus dismissing – contact surface hygiene is a serious error.

COVID and the brain: researchers zero in on how damage occurs
How COVID-19 damages the brain is becoming clearer. New evidence suggests that the coronavirus’s assault on the brain could be multipronged: it might attack certain brain cells directly, reduce blood flow to brain tissue or trigger production of immune molecules that can harm brain cells. Infection with the coronavirus SARS-CoV-2 can cause memory loss, strokes and other effects on the brain. The question, says Serena Spudich, a neurologist at Yale University in New Haven, Connecticut, is: “Can we intervene early to address these abnormalities so that people don’t have long-term problems?”

Study highlights need for full Covid vaccination to protect against Delta variant
A new study published Thursday in Nature adds new detail about the dominant variant, analyzing how well Delta, in a lab dish, was able to evade monoclonal antibody drugs such as bamlamivimab and natural antibodies made in our bodies after infection or vaccination. Looking at both kinds of antibodies in blood drawn from 162 patients and how they reacted to Delta, researchers from the Institut Pasteur in France found lower protection against the variant than against three other variants also notable for how easily they spread from person to person. “This is an important study for confirming the immune evasiveness property of Delta, which is a feature that adds to its enhanced transmissibility, making it the most formidable version of the virus to date,” Eric Topol, director and founder of the Scripps Research Translational Institute, told STAT. “No surprises, but further characterization of the variant, which reinforces why it is so challenging.”

mRNA vaccines slash risk of COVID-19 infection by 91% in fully vaccinated people
People who receive mRNA COVID-19 vaccines are up to 91 percent less likely to develop the disease than those who are unvaccinated, according to a new nationwide study of eight sites, including Salt Lake City. For those few vaccinated people who do still get an infection, or “breakthrough” cases, the study suggests that vaccines reduce the severity of COVID-19 symptoms and shorten its duration. Researchers say these results are among the first to show that mRNA vaccination benefits even those individuals who experience breakthrough infections. “One of the unique things about this study is that it measured the secondary benefits of the vaccine,” says Sarang Yoon, D.O., a study co-author, assistant professor at the University of Utah Rocky Mountain Center for Occupational and Environmental Health (RMCOEH), and principal investigator of the RECOVER (Research on the Epidemiology of SARS-CoV-2 in Essential Response Personnel) study in Utah. The study, published online in the New England Journal of Medicine, builds on preliminary data released by the Centers for Disease Control and Prevention (CDC) in March. The study was designed to measure the risks and rates of infection among those on the front lines of the pandemic.

Lambda variant: What is the new strain of Covid detected in the UK?
The Lambda variant - known to scientists as C.37 - was first identified in Peru and has been detected in samples dating back to as early as December 2020. Since then it has become the dominant variant in the South American country, where it accounts for more than 80 per cent of new infections. It has now been detected in at least 26 countries, including the UK. So should we be concerned? The World Health Organisation designated the Lambda variant as a variant of interest on 14 June.

COVID-19: UK seeing 'COVID Mexican wave' as virus spreads from west to east, says expert
The UK is seeing its "own form of a COVID Mexican wave" as infections move from the west of the country to the east, a leading symptoms researcher has said. Professor Tim Spector, co-founder of the ZOE COVID symptom study, said areas in the west which have been worst affected are now seeing lower rates, suggesting they have reached the peak of infections. However, London, the South East, East Anglia and eastern parts of the country are seeing cases increase, according to data from his study.

Scientists identify natural SARS-CoV-2 super immunity against 23 variants
A team of international scientists has recently identified ultrapotent anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies from convalescent donors. The antibodies are capable of neutralizing a wide range of SARS-CoV-2 variants even at sub-nanomolar concentrations. In addition, the combinations of these antibodies reduce the risk of generating escape mutants in vitro. The study is published in the journal Science.

Long Covid: More than two million in England may have suffered, study suggests
A survey of half a million adults in England suggests around two million people may have had some long-lasting symptoms after having coronavirus - sometimes known as "long Covid". The React study shows about a third of people who report they have coronavirus symptoms have one or more symptoms that persist for at least 12 weeks. Researchers say managing the long-term consequences are a "major challenge". The government has provided £50m for research into long Covid.

Vaccines ‘outpaced by variants’, WHO warns, as Delta now in 98 countries
Dr Tedros Adhanom Ghebreyesus, the director general of the WHO, said the sharing of vaccines was “only a trickle, which is being outpaced by variants”, after it emerged that the Delta variant is now present in at least 98 countries. His warning came as Dame Sarah Gilbert, the Oxford professor who led the team behind the Oxford/AstraZeneca vaccine, called for caution over proposals to vaccinate children in the UK. “We have to balance what we think about vaccinating children in high-income countries with vaccinating the rest of the world because we need to stop transmission of this virus globally,” she told the Observer.

Germany issues world's strongest recommendation for mixing Covid-19 vaccines
Germany has issued what appears to be the strongest recommendation anywhere for the mixing of Covid-19 vaccines on efficacy grounds. The German Standing Committee on Vaccination (STIKO) said Thursday that people who receive a first dose of the Oxford-AstraZeneca vaccine "should get an mRNA vaccine as their second dose, regardless of their age." This makes Germany one of the first countries to strongly recommend that people who have received a first dose of AstraZeneca receive either a Pfizer-BioNTech or Moderna vaccine as their second dose.

Research shows COVID-19-mRNA vaccine efficiency against coronavirus variants
A new Finnish study shows that 180 health care workers who had received two doses of the Pfizer and Biontech vaccine have very good antibody responses against the SARS-CoV-2 virus. The immune response was as strong against the alpha variant (formerly the UK variant) but was somewhat decreased against the beta variant (formerly the South Africa variant). Finnish researchers from the University of Turku and University of Helsinki together with Turku University Hospital, Helsinki University Hospital, and the Finnish Institute for Health and Welfare studied the immune response induced by the coronavirus vaccinations, which started in Finland in December. The researchers analysed vaccine responses in 180 health care workers, each of whom received two doses of the Pfizer and Biontech mRNA vaccine.

CureVac COVID-19 vaccine records only 48% efficacy in final trial readout
CureVac said its COVID-19 vaccine was 48% effective in the final analysis of its pivotal mass trial, only marginally better than the 47% reported after an initial read-out two weeks ago. The German biotech firm said that efficacy, measured by preventing symptomatic disease, was slightly better at 53% when excluding trial participants older than 60 years, an age group that is by far the most severely affected. CureVac said on June 16 its COVID-19 vaccine, known as CVnCoV, proved only 47% effective in an initial trial read-out and that new variants had proved a headwind, denting investor confidence in its ability to take on rival shots.

Pfizer and Moderna Vaccines Are Likely to Produce Long-Lasting Immunity, Study Suggests
The vaccines made by Pfizer-BioNTech and Moderna set off a persistent immune reaction in the body that may protect against the coronavirus for years, scientists reported on Monday. The findings add to growing evidence that most people immunized with the mRNA vaccines may not need boosters, so long as the virus and its variants do not evolve much beyond their current forms — which is not guaranteed. People who recovered from Covid-19 before being vaccinated may not need boosters even if the virus does make a significant transformation. “It’s a good sign for how durable our immunity is from this vaccine,” said Ali Ellebedy, an immunologist at Washington University in St. Louis who led the study, which was published in the journal Nature.

Delta Covid variant may be edging race against vaccines
The transmission advantage of the Delta variant that is spreading at pace globally is a sign that the race between vaccination and the virus could tip in favour of the latter unless countries ramp up their immunisation campaigns and practise caution, scientists say. The variant, first detected in India, has been identified in at least 92 countries and is considered the “fittest” variant yet of the virus that causes Covid-19, with its enhanced ability to prey on the vulnerable – particularly in places with low vaccination rates. Research conducted in the UK, where the variant accounts for 99% of new Covid cases, suggests it is about 60% more transmissible than the Alpha variant, which previously dominated. It may also be linked to a greater risk of hospitalisation and is somewhat more resistant to vaccines, particularly after one dose.

Why reports of COVID-19 infections after 2 vaccine doses aren't cause for alarm
A Toronto hospital recently announced an outbreak involving cases among people who'd received one or both vaccine doses. Back in May, nine cases of COVID-19 were reported in just one week among fully-vaccinated members of the New York Yankees baseball team and its staff. And across Canada, deaths from the illness have even been reported among individuals who've had two shots, including a senior in Manitoba in May and an elderly long-term care resident in Ontario a month later. But there are two key things to keep in mind about these "breakthrough infections." For one thing, they're rare — making up around 0.5 per cent of reported COVID-19 cases since vaccination efforts began, the latest Canadian data shows. And when post-vaccination infections do happen, they typically tend to be mild.

Pfizer and Moderna Vaccines Immunize For Up to Three Years
COVID-19 vaccines developed with new messenger RNA technology, currently those produced by Moderna and Pfizer-BioNTech, can prevent an adult from severe COVID-19 cases for three years, according to a study by Swiss scientists released on June 25. As reported by La Opinion de Malaga, the research, published by the Swiss Government’s Scientific Working Group against covid-19, reduces, however, to 16 months the possible immunity of those vaccinated with this type of vaccine against moderate forms of the virus. According to Swiss scientists, the Moderna and Pfizer-BioNTech vaccines, the only ones currently administered in Spain, create an antibody response between two and four times greater than that presented by those who have overcome the disease, which means longer-lasting protection.

Delta Variant Outbreak in Israel Infects Some Vaccinated Adults
About half of adults infected in an outbreak of the Delta variant of Covid-19 in Israel were fully inoculated with the Pfizer Inc. vaccine, prompting the government to reimpose an indoor mask requirement and other measures to contain the highly transmissible strain. Preliminary findings by Israeli health officials suggest about 90% of new infections were likely caused by the Delta variant, according to Ran Balicer, who leads an expert advisory panel on Covid-19 for the government. Children under 16, most of whom haven’t been vaccinated, accounted for about half of those infected, he said. The government this week expanded its vaccination campaign to include all 12- to 15-year-olds after a jump in infections among schoolchildren in a town in central Israel. It has since quickly spread geographically and to other groups of the population.

Scientist's hunt for COVID-19's origin finds early virus sequences Chinese team deleted from NIH database
In a world starved for any fresh data to help clarify the origin of the COVID-19 pandemic, a study claiming to have unearthed early sequences of SARS-CoV-2 that were deliberately hidden was bound to ignite a sizzling debate. The unreviewed paper, by evolutionary biologist Jesse Bloom of the Fred Hutchinson Cancer Research Center, asserts that a team of Chinese researchers sampled viruses from some of the earliest COVID-19 patients in Wuhan, China, posted the viral sequences to a widely used U.S. database, and then a few months later had the genetic information removed to “obscure their existence.” To some scientists, the claims reinforce suspicions that China has something to hide about the origins of the pandemic. But critics of the preprint, posted yesterday on bioRxiv, say Bloom’s detective work is much ado about nothing, because the Chinese scientists later published the viral information in a different form, and the recovered sequences add little to what’s known about SARS-CoV-2’s origins.

Next steps for wastewater testing to help end this pandemic — and prevent the next one
During the early months of the Covid-19 pandemic, cities began tapping their wastewater to look for evidence of SARS-CoV-2, the virus that causes Covid-19. Now, more than a year into the pandemic, it’s clear that sewage surveillance carries several advantages over traditional surveillance. Unlike individual testing, wastewater testing captures virus shed by symptomatic and asymptomatic people alike, and can test en masse the 80% of U.S. households connected to a sewer system. Such testing can detect exactly when dangerous viral variants enter a community and provide an early warning to public officials. It can even predict new outbreaks with a lead time of one to two weeks.

How Immunity Generated from COVID-19 Vaccines Differs from an Infection
A key issue as we move closer to ending the pandemic is determining more precisely how long people exposed to SARS-CoV-2, the COVID-19 virus, will make neutralizing antibodies against this dangerous coronavirus. Finding the answer is also potentially complicated with new SARS-CoV-2 “variants of concern” appearing around the world that could find ways to evade acquired immunity, increasing the chances of new outbreaks. Now, a new NIH-supported study shows that the answer to this question will vary based on how an individual’s antibodies against SARS-CoV-2 were generated: over the course of a naturally acquired infection or from a COVID-19 vaccine. The new evidence shows that protective antibodies generated in response to an mRNA vaccine will target a broader range of SARS-CoV-2 variants carrying “single letter” changes in a key portion of their spike protein compared to antibodies acquired from an infection. These results add to evidence that people with acquired immunity may have differing levels of protection to emerging SARS-CoV-2 variants. More importantly, the data provide further documentation that those who’ve had and recovered from a COVID-19 infection still stand to benefit from getting vaccinated.

The news was originally reported by inews on the weekend and shows that cases in the area which hosted the summit have risen by almost 2,500% since the event, causing significant alarm for local businesses and residents of the tourism-heavy area. Despite reasonably high vaccination rates, the U.K. is experiencing a significant surge in cases fueled by the Delta SARS-CoV2 variant originally discovered in India. Despite this, the U.K. is not currently experiencing a substantial rise in deaths, likely due to this surge being mostly driven by children and younger adults who have not yet been vaccinated, whereas the large majority of older adults and clinically vulnerable people have been fully vaccinated.

Persistent pulmonary disease after acute covid-19
Lingering pathology contributes to a wider picture of poor health after hospital discharge It has been over a year since the first patients were discharged from UK hospitals following treatment for covid-19. Hospital admission was largely dictated by the requirement for supplementary oxygen and additional respiratory support.1 Acute imaging commonly showed multifocal airspace opacification, and venous thromboembolism was recorded in around a quarter of adults admitted to critical care.2 This led to concern about the long term respiratory consequences of covid-19, particularly interstitial lung disease and pulmonary vascular disease.3
Fifteen months later, our understanding of the complications after hospital treatment for covid-19 is improving. A UK study of 47 780 discharged patients reported all cause mortality of 12% and readmissions in one third after 140 days of follow-up.4 Interestingly, although respiratory disease was diagnosed in 29.6% after discharge, rates of extrapulmonary complications, including diabetes, adverse cardiovascular events, and liver and kidney dysfunction were also increased compared with those in population matched controls, indicating that the effect of covid-19 extends far beyond the lungs.

Oxford University explores anti-parasitic drug ivermectin as COVID-19 treatment
The University of Oxford said on Wednesday it was testing anti-parasitic drug ivermectin as a possible treatment for COVID-19, as part of a British government-backed study that aims to aid recoveries in non-hospital settings. Ivermectin resulted in a reduction of virus replication in laboratory studies, the university said, adding that a small pilot showed giving the drug early could reduce viral load and the duration of symptoms in some patients with mild COVID-19

Surging infections divide UK airlines and gov’t on reopening
Britain’s surging coronavirus infection rate is widening a rift between airlines and health authorities over the government’s decision to maintain some of the tightest rules on travel in Europe. Travel industry officials plan to hold events on Wednesday in London, Edinburgh and Belfast to draw attention to some 195,000 jobs they say are at risk from restrictions on overseas trips. An adviser from Public Health England meanwhile warned that a fourth national lockdown may be needed this year to control the virus.

Israeli study links pre-infection vitamin D deficiency with severe COVID-19 illness
Israeli researchers have found that pre-infection deficiency of vitamin D is associated with increased COVID-19 severity and mortality, Bar Ilan University (BIU) said Monday. The study conducted by BIU and the Galilee Medical Center (GMC) assessed the correlation using low levels of vitamin D measured prior to infection and focused on disease severity. In the study, the records of COVID-19 patients who were admitted to GMC were searched for vitamin D levels measured 14 to 730 days prior to the positive test. It was found that compared with mildly or moderately diseased patients, those with severe or critical COVID-19 disease were more likely to have severe pre-infection vitamin D deficiency with levels less than 20 ng/mL.

Cuba encouraged by early efficacy results of COVID-19 vaccine
Cuba’s Soberana 2 vaccine candidate has shown 62 percent efficacy with just two of its three doses, state-run biopharmaceutical corporation BioCubaFarma has said, citing preliminary data from late phase trials. Cuba, whose biotech sector has exported vaccines for decades, has five vaccine candidates in clinical trials, of which two – Soberana 2 and Abdala – are in late phase trials. “In a few weeks we should have the results for the efficacy with three doses which we expect will be superior,” said Vicente Vérez, director of the state-run Finlay Vaccine Institute, which developed Soberana 2. The news comes as the Caribbean’s largest island is facing its worst outbreak since the start of the pandemic in the wake of the arrival of more contagious variants, setting new records of daily coronavirus cases.

Covid-19 vaccine side effects: Women hope more research will discover if jab causing period problems
Women around the world have been asking for several months whether early, heavy or painful periods might be an unlisted side effect to the Covid vaccine. The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has received reports from more than 4,000 women who suffered period problems after having their jab. Some 2,734 reports are linked to the Oxford/AstraZeneca vaccine, 1,158 related to the Pfizer/BioNtech jab, and 66 linked to the Moderna vaccine, up to May 17. The numbers roughly reflect the proportion of each vaccine in the UK’s vaccination programme. The majority of issues were reported in women aged between 30 and 49 and typically involved “heavier than usual” bleeding. Other issues included delayed periods and unexpected vaginal bleeding. The watchdog said it is “closely monitoring” the reports having said a review with experts found that there was no need to list the problem as a potential side effect alongside common issues such as a sore arm, fatigue or nausea.

You can catch covid-19 twice, but the second bout is likely to be mild
Back in August 2020, a worrying report came in from Reno, Nevada. A 25-year-old man who had recovered from covid-19 in April had fallen ill with it again, and this time his symptoms were worse. He had tested negative for the virus in between bouts, so had been infected twice. Other reports of reinfection were also circulating at the time, raising fears that infections don’t lead to long-lasting immunity. Nine months on, however, those fears have receded...

Delta Covid variant becoming globally dominant – WHO official
The Delta variant of Covid-19, first identified in India, is becoming the globally dominant variant of the disease, the World Health Organisation’s chief scientist said yesterday. Britain has reported a steep rise in infections with the Delta variant, while Germany’s top public health official predicted it would rapidly become the dominant variant there despite rising vaccination rates. The Kremlin blamed a surge in Covid-19 cases on reluctance to have vaccinations and “nihilism” after record new infections in Moscow, mostly with the new Delta variant, fanned fears of a third wave

How COVID vaccines work against the Delta variant
The Delta variant of coronavirus is a source of serious concern as lab tests have shown it is more contagious and resistant to vaccines compared with other forms of COVID-19. However, there is evidence that the available jabs retain important effectiveness against it after two doses. A British study published in The Lancet medical journal in early June looked at levels of neutralising antibodies produced in vaccinated people exposed to the Delta, Alpha (first identified in Britain) and Beta (first identified in South Africa) variants. It found that antibody levels in people with two doses of the Pfizer-BioNTech shot were six times lower in the presence of the Delta variant than in the presence of the original COVID-19 strain on which the vaccine was based. The Alpha and Beta variants also provoked lower responses, with 2.6 times fewer antibodies for Alpha and 4.9 times fewer for Beta.

Previous Covid infection may not offer long-term protection, study finds
Previous infection with coronavirus does not necessarily protect against Covid in the longer term, especially when caused by new variants of concern, a study on healthcare workers suggests. Researchers at Oxford University found marked differences in the immune responses of medical staff who contracted Covid, with some appearing far better equipped than others to combat the disease six months later. Scientists on the study, conducted with the UK Coronavirus Immunology Consortium, said the findings reinforced the importance of everyone getting vaccinated regardless of whether they had been infected with the virus earlier in the pandemic.

CureVac’s coronavirus vaccine only 47 percent effective
German company CureVac's coronavirus vaccine is far less effective than other jabs already in use, the firm said Wednesday. The company announced a 47 percent efficacy rate against all COVID-19 cases and said it "did not meet prespecified statistical success criteria" based on the second analysis of a large-scale efficacy trial. The study involved 40,000 people in 10 countries in Europe and Latin America with at least 13 coronavirus variants circulating, the company said. The "original strain" was "almost completely absent" from the trial.

Covid-19: Regeneron's antibody combination cuts deaths in seronegative patients, trial finds
Regeneron’s antibody combination treatment cut deaths in seronegative patients—meaning those who had not mounted their own antibody response to covid-19—by one fifth, the Recovery trial has found. The researchers found that for every 100 seronegative patients treated with the combination of casirivimab and imdevimab, there were six fewer deaths. They said patients admitted to hospital should now be routinely tested for antibodies to determine whether the treatment could benefit them. The two virus neutralising antibodies work by binding non-competitively to the critical receptor binding domain of SARS-CoV-2’s spike protein, thereby stopping the virus from binding to and entering human cells. Recovery, which is being carried out in 177 UK hospitals, has been evaluating potential covid-19 treatments for patients admitted to hospital. It discovered the first effective treatment for reducing mortality—dexamethasone—while also discounting others including hydroxychloroquine and convalescent plasma.

Delta variant fuelled 50% rise in English COVID prevalence -study
The rapid spread of the Delta coronavirus variant has driven a 50% rise in infections in England since May, a large prevalence study led by Imperial College London found on Thursday after Prime Minister Boris Johnson delayed the end of restrictions. The government said the data supported Johnson’s decision to push back the end of COVID restrictions in England to July 19, citing the threat of the Delta variant first identified in India, and the need to vaccinate more people. The latest round of the REACT-1 prevalence survey, conducted between May 20 and June 7, found prevalence was 0.15%, compared to 0.10% in the last set of data from late April to early May.

Can you mix and match COVID-19 vaccines?
Can you mix and match two-dose COVID-19 vaccines? It’s likely safe and effective, but researchers are still gathering data to be sure. The authorized COVID-19 shots around the world are all designed to stimulate your immune system to produce virus-fighting antibodies, though the way they do so varies, noted Dr. Kate O’Brien, director of the World Health Organization’s vaccine unit. “Based on the basic principles of how vaccines work, we do think that the mix-and-match regimens are going to work,” she said. Scientists at Oxford University in the United Kingdom are testing combinations of the two-dose COVID-19 vaccines made by AstraZeneca, Moderna, Novavax and Pfizer-BioNTech. Smaller trials are also ongoing in Spain and Germany. “We really just need to get the evidence in each of these (vaccine) combinations,” O’Brien said.

Pfizer’s arthritis drug Xeljanz shows lifesaving benefits in hospitalized COVID-19 patients
Pfizer’s BioNTech-partnered COVID-19 vaccine Comirnaty may be getting all the attention these days, but the pharma giant’s anti-inflammatory drug Xeljanz just chalked up a win in treating patients hospitalized with the disease. Xeljanz reduced the risk of death or respiratory failure among hospitalized patients with COVID-19 pneumonia who didn’t require ventilation, according to data published in the New England Journal of Medicine. The company is now analyzing the full dataset and will assess the next steps, Tamas Koncz, M.D., Ph.D., chief medical officer of Pfizer Inflammation & Immunology, said in a statement Wednesday. The data come from the STOP-COVID study, which enrolled 289 hospitalized patients across 15 sites in Brazil. After 28 days of treatment, death or respiratory failure had occurred in 18.1% of patients on Xeljanz, compared with 29% for those who received placebo. All patients also received other standard-of-care treatments, including corticosteroids, which were given to nearly 90% of patients in both trial arms.

New COVID-19 variant of interest identified in 29 countries: WHO
The World Health Organization (WHO) said Wednesday that a new variant of COVID-19, named Lambda, was identified in 29 countries and notably in South America where it is believed to have originated. First identified in Peru, the Lambda lineage was classified as a global Variant of Interest on Monday due to an “elevated prevalence” in South America, the WHO said in its weekly update. Lambda has been rampant in Peru where 81 percent of COVID-19 cases since April 2021 were associated with this variant, authorities reported. In Chile, it was detected in 32 percent of all submitted sequences in the last 60 days, and only outclassed by the Gamma variant which was first identified in Brazil. Other countries such as Argentina and Ecuador have also reported elevated prevalence of the new variant.

Regeneron COVID-19 therapy cuts deaths among hospitalised patients who lack antibodies -study
A COVID-19 antibody cocktail developed by Regeneron Pharmaceuticals Inc and Roche reduced deaths in hospitalised patients whose own immune systems had failed to produce a response, a large British study found on Wednesday. The therapy, REGEN-COV, has been granted emergency use authorisation for people with mild-to-moderate COVID-19 in the United States, but results from the RECOVERY trial provide the clearest evidence of its effectiveness among hospitalised patients. It found that the antibody therapy reduced by a fifth the 28-day mortality of people admitted to hospital with COVID-19 whose immune system had not mounted an antibody response, known as seronegative.

Sewage sleuths helped an Arizona town beat back Covid-19. For wastewater epidemiology, that’s just the start
Valerie Molina anxiously searched the desert sky, scanning the horizon for any clouds dark with rain. But all was blue and bright. Today, the weather wasn’t going to be on her side. It was March 20, 2020, and Guadalupe, over which Molina presides as mayor, was preparing for what should have been the third of six Friday ceremonies in the run-up to Easter. Normally, it’s the time of year when the town of 6,700 doubles in size, as spectators from across the state descend on its white adobe church to witness young men in wooden masks, a sacred deer antler headdress, and ankle rattles made from the cocoons of butterflies dance to beating drums beneath ribbons of flowers. Guadalupe was founded by Pascua Yaqui Indians who were forced from their homelands in Sonora, Mexico, and settled in the Salt River Valley in the early 1900s, bringing with them their unique religion — a blend of spiritual animism and Catholic beliefs picked up from Jesuit missionaries.

Covid-19: Irish scientists discover link to life threatening blood clots
Irish scientists have identified how and why some Covid-19 patients can develop life-threatening blood clots. The work ,led by researchers at the Royal College of Surgeons in Ireland (RCSI), could lead to targeted therapies that prevent such clots happening in future. The findings are published in the Journal of Thrombosis and Haemostasis. The scientists analysed samples from Covid-19 patients in intensive care in the Beaumont Hospital in Dublin. They found the balance between a molecule that causes clotting called the von Willebrand Factor (VWF) and its regulator, ADANTS 13, is severely disrupted in Covid patients who had elevated levels of the VWF protein.

Two shots of Pfizer, AstraZeneca COVID-19 vaccines effective against Delta variant: study
As the coronavirus surged across the globe, experts have raised concerns that skyrocketing infections would cause mutations that evade current vaccines. As more data comes in, those concerns are fading. A real world study conducted by Public Health England shows that two doses of the vaccines produced by Pfizer-BioNTech and AstraZeneca are highly effective in preventing hospitalizations due to the troublesome Delta variant (B.1.617.2), which scientists first detected in India. The variant has become the predominant coronavirus strain in the U.K. Of those who received two doses of the Pfizer-BioNTech vaccine, 96% avoided hospitalization with no deaths. Of those who received two shots of the AZ vaccine, 92% avoided hospitalization with no deaths. The study included 14,019 people in England who had contracted the Delta variant of the virus. Of them, 166 were hospitalized from April 12 to June 4.

Seqirus Co-Authors First Study to Assess Simultaneous Administration of Seasonal Influenza Vaccine and COVID-19 Vaccine Candidate
Seqirus, a global leader in influenza prevention and a division of CSL Limited (ASX: CSL), today announced that the company co-authored the first study to demonstrate the safety, immunogenicity and efficacy profile of a COVID-19 vaccine when co-administered with a seasonal influenza vaccine.1 The data is now available on medRxiv ahead of peer-review publication. The study was conducted by Novavax, Inc. as part of a Phase 3 clinical trial of NVX-CoV2373, its recombinant protein COVID-19 vaccine candidate, in the United Kingdom.1 The co-administration sub-study enrolled 431 volunteers, all of whom received either an adjuvanted, trivalent seasonal influenza vaccine (aTIV) or a cell-based, quadrivalent seasonal influenza vaccine (QIVc) provided by Seqirus.1 Approximately half of the volunteers also received NVX-CoV2373 while the remainder received the placebo. The study results suggest that efficacy of both the influenza vaccine and the COVID-19 vaccine candidate appeared to be preserved.1 No additional safety concerns were found with co-administration and adverse events were similar to the incidence and severity for each vaccine when administered separately.

Delta variant Covid symptoms ‘include headaches, sore throat and runny nose’
The data, collected as part of the app-based Zoe Covid symptom study, suggests that the Delta variant first detected in India feels like a “bad cold”, according to Tim Spector, a professor of genetic epidemiology at King’s College London, who is leading the work. “Covid is … acting differently now, it’s more like a bad cold,” he said. “People might think they’ve just got some sort of seasonal cold, and they still go out to parties … we think this is fuelling a lot of the problem. So, what’s really important to realise is that since the start of May, we’ve been looking at the top symptoms in all the app users, and they’re not the same as they were. So, the number one symptom is headache … followed by sore throat, runny nose and fever.”

Association Between Bitter Taste Receptor Phenotype and Clinical Outcomes Among Patients With COVID-19
Bitter taste receptors (T2Rs) have been implicated in sinonasal innate immunity, and
genetic variation conferred by allelic variants in T2R genes is associated with variation in upper respiratory tract pathogen susceptibility, symptoms, and outcomes. Bitter taste receptor phenotype appears to be associated with the clinical course and symptom duration of SARS-CoV-2 infection. A prospective cohort study was performed from July 1 through September 30, 2020, at a tertiary outpatient clinical practice and inpatient hospital in the United States among 1935 participants (patients and health care workers) with occupational exposure to SARS-CoV-2. This cohort study suggests that T2R38 receptor allelic variants were associated with participants’ innate immune response toward SARS-CoV-2. The T2R phenotype was associated with patients’ clinical course after SARS-CoV-2 infection

Strong immune response protects young children from Covid-19, suggests study
Young children have relative protection from coronavirus because their bodies produce a strong immune response to it, according to a new study. The University of Bristol and Bristol Royal Hospital for Children conducted research which found that infants produce relatively high levels of antibodies and immune cells which protect against the virus, compared to adults. Researchers say the findings could help explain why younger children appear to be protected from the severe effects of Covid-19 at a time of their development when they could be more vulnerable.
The study was led by academics and paediatricians from the university and hospital and is published in Cell Reports Medicine.

Delta variant causes more than 90% of new Covid cases in UK
More than 90% of Covid cases in the UK are now down to the coronavirus Delta variant first discovered in India, data has revealed, as the total number of confirmed cases passed 42,000. Also known as B.1.617.2, the Delta variant has been linked to a rise in Covid cases in the UK in the past weeks. It is believed to spread more easily than the Alpha variant, B.1.1.7, that was first detected in Kent, and is somewhat more resistant to Covid vaccines, particularly after just one dose. It may be also associated with a greater risk of hospitalisation. Now, Public Health England (PHE) has said that more than 90% of new Covid cases in the UK involve the Delta variant. Indeed the most recent data suggests the figure could be as high as 96% of new cases in England.

The COVID-19 virus can cause diabetes, new studies find
There is troubling news for those infected with the COVID-19 virus. New studies have found that the virus may cause diabetes in addition to pneumonia and other health problems. Most people will recover from COVID without longer-term problems, but doctors have noticed that some patients go on to develop diabetes. Now, new research is finding that the virus may infect and destroy certain cells that are crucial for keeping diabetes at bay. Armed with this new knowledge, scientists are now racing to understand how to best prevent this from happening in patients with COVID-19.

AstraZeneca covid-19 vaccine may hinder blood clotting in rare cases
The Oxford/AstraZeneca coronavirus vaccine may be associated with a slightly increased risk of some bleeding disorders, according to new data, but such cases are very rare and the vaccine’s benefits continue to outweigh the risks, say researchers. An analysis of people who received a first dose of the Oxford/AstraZeneca or Pfizer/BioNTech vaccine revealed a small increased risk of an autoimmune bleeding condition known as immune thrombocytopenic purpura (ITP) associated with the Oxford/AstraZeneca vaccine, separate to the blood clotting syndrome that was linked to the vaccine previously. In ITP, the immune system destroys platelets, the blood cells that help the blood to clot. The condition can cause minor bruising in some people and excessive bleeding and long-term illness in others, but the symptoms are usually mild and death from ITP is very rare.

A 'Universal' Coronavirus Vaccine to Prevent the Next Pandemic
In the past 20 years alone, three coronaviruses have caused major disease outbreaks. First came the original SARS virus in 2002. Then, in 2012, MERS was identified. In 2019 SARS-CoV-2 emerged, setting off a global pandemic. Hundreds of other coronaviruses are known to be circulating in bats and other animals. Scientists have warned that some of them could emerge in the future and potentially infect people. Our current COVID-19 vaccines were specifically designed for SARS-CoV-2, but what if a next-generation vaccine could protect against both known and unknown coronaviruses? Scientists at the Walter Reed Army Institute of Research in Silver Spring, Md., are working on a so-called universal coronavirus vaccine. Dr. Kayvon Modjarrad is leading the effort.

Johnson & Johnson vaccine effective against variants: study | TheHill
The Johnson & Johnson COVID-19 vaccine produces several immune responses allowing it to be effective against different variants of the virus, according to a study released Wednesday. The research, published in Nature as an accelerated article preview, determined that the Johnson & Johnson vaccine activated immune responses against the original COVID-19 strain, as well as the Alpha, Beta, Gamma and Epsilon variants. The study concluded that the Johnson & Johnson vaccine “offered strong protection against symptomatic” cases of COVID-19 in South Africa and Brazil where variants have caused most sequenced cases. Researchers studied the antibody and cellular immune responses of 20 volunteers between the ages of 18 and 55.

AstraZeneca vaccine linked to slightly higher risk of blood disorder
Data from Scotland’s Covid vaccination programme has revealed a possible small increase in the risk of a treatable and often mild bleeding disorder after the first dose of the Oxford/AstraZeneca vaccine. Doctors examined the medical records of 5.4 million people in Scotland for instances of blood clots, unusual bleeding, and a condition called idiopathic thrombocytopenic purpura (ITP), where a reduction in blood platelets can lead to easy bruising, bleeding gums and internal bleeding. The analysis conducted with Public Health Scotland found the risk of ITP was marginally higher in the 1.7 million people who had received a first dose of the Oxford/AstraZeneca vaccine than in a comparison group that did not receive the shot up to 14 April 2021.

Research now backs routinely offering pregnant women the mRNA COVID-19 vaccine
New Zealand and Australia will now routinely offer the Pfizer COVID-19 vaccine to women at any stage of pregnancy, following an update of vaccination advice. This comes as research suggests the risk of severe outcomes from infection is significantly higher for pregnant women compared to the general population. At the same time, data from pregnant women who have already been vaccinated around the world have shown no safety concerns associated with COVID-19 vaccines. Vaccination during pregnancy may also protect the baby. Research has identified antibodies in cord blood and breast milk, suggesting temporary protection (passive immunity) for babies before and after birth.

A third dose of coronavirus vaccine could be beneficial for some
Giving a third dose of a coronavirus vaccine to residents and staff of residential care centres would be beneficial, Belgium’s Public Health Institute Sciensano said Wednesday, basing their conclusion on the PICOV-VAC study conducted in January in two care centres in the country. While all participants, young and old, made antibodies against the coronavirus after receiving two doses of the BioNTech/Pfizer vaccine, the study found that the number of antibodies made after receiving the BioNTech/Pfizer vaccine was much higher in people who had been infected with Covid-19 before vaccination.

What's Happening With Johnson & Johnson's Covid-19 Vaccine?
J&J is making some progress with its international rollout. The single-dose vaccine was authorized for emergency use by the U.K. regulator in late May and the U.K has ordered 20 million doses of the shot that is likely to be available later this year. J&J also filed for regulatory approval of the vaccine in Japan, noting that it could begin supplying doses to the country by 2022. Japan has made little progress with its vaccination drive so far, with less than 4% of its population fully vaccinated. The company is also looking to expand the vaccine's availability to India, working with manufacturer Biological E. to produce its shot locally. Overall, we still think the J&J shot has room for growth globally, as it could do much of the heavy lifting in getting the global population inoculated against Covid-19, considering its single-dose requirement and relatively easy storage.

We’ll Probably Need Booster Shots for Covid-19. But When? And Which Ones?
As the nation edges closer to President Biden’s goal of a 70 percent vaccination rate, many people are beginning to wonder how long their protection will last. For now, scientists are asking a lot of questions about Covid-19 booster shots, but they don’t yet have many answers. The National Institutes of Health recently announced that it has begun a new clinical trial of people fully vaccinated — with any authorized vaccine — to see whether a booster of the Moderna shot will increase their antibodies and prolong protection against getting infected with the virus.

Swapping vaccines may be beneficial against Covid-19, German study suggests
Taking the AstraZeneca jab and then having the Pfizer shot ten weeks later could result in stronger immunity than sticking with the same vaccine for both doses, a German study suggests. The experiment is one of the first to indicate that swapping vaccines may be not only safe and effective but potentially beneficial. However, the research is still in its early days and much remains to be learnt about how various combinations work. There has been much speculation that patients who receive two vaccines based on separate underlying technologies might acquire better protection against Covid-19. This is because the vaccines elicit different forms of immune response from the body.

Would you have your DNA tested to predict how hard COVID-19 would strike? Should you?
For people not yet vaccinated against COVID-19 or still nervous about venturing into crowds, the sales pitch may be alluring: Drool into a tube to provide your DNA and mail it off to see how likely you are to be among the 10% to 15% of people who will end up in the hospital or die from a SARS-CoV-2 infection. That’s the promise of a test an Australian company launched last week in the United States. It combines genetic data with someone’s age, sex, and preexisting medical conditions to predict their risk of becoming extremely ill from COVID-19. The $175 test is based on genetic markers linked to severe COVID-19, along with other risk factors, and the company says it developed its predictions using data on thousands of COVID-19 patients in the United Kingdom. It may be a forerunner of similar risk tests: An academic team has recently detailed a simpler genetic test to help determine how aggressively some people infected with SARS-CoV-2 should be treated.

‘Mix and match’ Covid booster jabs may be offered in UK
Ministers are considering giving people a different type of Covid vaccine as an autumn booster, it has emerged, after early results from “mix and match” trials appeared to show promise for an enhanced immune response. Four different coronavirus jabs have been approved for use in the UK, with more under regulatory review. While people are currently offered two doses of the same jab, researchers have been exploring whether offering a second dose of a different Covid vaccine could generate a stronger immune response. It is also expected that people will be offered a third, “booster” injection, potentially in the autumn, in part to protect them against variants with some resistance to existing vaccines. One possibility being looked at is that this third jab could be of a different type to people’s initial two, a government source said.

Covid-19: PPE guidance is upgraded as evidence of airborne transmission grows
More NHS staff caring for patients with suspected or confirmed covid-19 will have access to higher grade personal protective equipment (PPE), including FFP3 masks, under updated NHS guidance on covid-19 infection prevention and control.
Issued this week, the updated guidance obliges NHS organisations to assess the risk that covid-19 poses to staff and to act to mitigate any risks, such as by providing higher grade PPE including FFP3 masks. These risk assessments should include evaluations of ventilation, operational capacity, and the prevalence of infections including new variants of concern in the local area. The guidance also provides updates on the use of valved respirators and upper gastrointestinal endoscopy, advising that extended use of gowns must be minimised, with sessional use taking place only in areas where all patients have confirmed covid-19. The BMA, which has led calls for better PPE throughout the pandemic,2 described the updated guidance as “a step in the right direction.”

More evidence of frequent antibiotic use noted in COVID patients
Research published yesterday in The Lancet Microbe shows that COVID-19 patients in the United Kingdom in the first wave of the pandemic rarely had bacterial co-infections or secondary infections, yet frequently received antibiotics. The study by a team of UK researchers looked at data from more than 48,000 COVID-19 patients treated at 260 hospitals in England, Scotland, and Wales from Feb 6 through Jun 8, 2020, and found that only 13% had bacterial co-infections or secondary infections. But 85% received one or more antibiotics during their hospital stay, with broad-spectrum antibiotics used frequently, and more than a third received antibiotics for their illness before being hospitalized. While several retrospective studies and reviews on antibiotic use in COVID-19 patients have been conducted over the course of the pandemic, and similar findings of low co-infection and high antibiotic use reported, this is the first prospective study of the issue. The authors describe it as the most comprehensive analysis of its kind to date, providing microbiologic details on laboratory-confirmed co-infections and secondary infections in COVID-19 patients.

Israel reports link between rare cases of heart inflammation and COVID-19 vaccination in young men
The COVID-19 vaccine made by Pfizer and BioNTech appears to put young men at elevated risk of developing a heart muscle inflammation called myocarditis, researchers in Israel say. In a report submitted today to the Israeli Ministry of Health, they conclude that between one in 3000 and one in 6000 men ages 16 to 24 who received the vaccine developed the rare condition. But most cases were mild and resolved within a few weeks, which is typical for myocarditis. “I can’t imagine it’s going to be anything that would cause medical people to say we shouldn’t vaccinate kids,” says Douglas Diekema, a pediatrician and bioethicist at Seattle Children’s Hospital.

Scientists call on UK to speed up second Covid jabs as India variant spreads
Scientists are urging the government to speed up second doses of Covid vaccines and delay a decision on easing lockdown restrictions in England on 21 June in an effort to tackle the creeping spread of new cases. Data has shown the coronavirus variant first detected in India, known as B.1.617.2, is continuing to spread across England, and is thought to be driving a rise in cases. It is believed to be both more transmissible than the variant first detected in Kent, which previously dominated, and somewhat more resistant to Covid vaccines, particularly after one dose. The situation has led some scientists to warn the country is in the early stages of a third wave of coronavirus which, despite the vaccination programme, modelling suggests could lead to a rise in hospitalisations and deaths, and that full easing of restrictions in England in three weeks’ time should be reconsidered.

An official Canadian panel on Tuesday said people who received a first shot of AstraZeneca PLC's (AZN.L) COVID-19 vaccine can choose to receive a different shot for their second dose, dealing another potential blow to the pharmaceutical giant. Theresa Tam, Canada's chief public health officer, said one reason for the recommendation by the National Advisory Committee on Immunization (NACI) was concern about rare and potentially fatal blood clots linked to the AstraZeneca vaccine. "If it weren't for that, then probably one would progress with giving the same (vaccine) as a second dose," she said.

Israel sees probable link between Pfizer vaccine and small number of myocarditis cases
Israel’s Health Ministry said on Tuesday it found the small number of heart inflammation cases observed mainly in young men who received Pfizer’s COVID-19 vaccine in Israel were likely linked to their vaccination. Pfizer has said it has not observed a higher rate of the condition, known as myocarditis, than would normally be expected in the general population. On Tuesday, it did not immediately respond to a request for comment. In Israel, 275 cases of myocarditis were reported between December 2020 and May 2021 among more than 5 million vaccinated people, the ministry said, in disclosing the findings of a study it commissioned to examine the matter

Britain seeks extra AstraZeneca shots to combat 'beta' COVID-19 variant
Britain is in talks with Oxford and AstraZeneca (AZN.L) for additional doses of their COVID-19 vaccine that has been modified to better target the "beta" coronavirus variant first identified in South Africa, and it will fund trials of the shots. Britain has previously secured 100 million doses of the vaccine, developed at the University of Oxford and licenced to AstraZeneca, and the health ministry said the extra doses under discussion would be tailored to target the B.1.351 variant. South Africa put use of AstraZeneca's shot on hold in February after data showed it gave minimal protection against mild-to-moderate infection caused by the country's dominant variant, now known as "beta" under a new World Health Organization labelling system

Sinovac Biotech vaccine effective in controlling Covid-19, new study shows
The vaccine developed by Sinovac Biotech was effective in controlling Covid-19 in a mass-inoculation study in a small Brazilian town after 75 per cent of adults were covered with a second shot, preliminary numbers show. The study carried out by the Sao Paulo state government in the small town of Serrana - population 45,000 - may offer clues for other developing nations on how much of the public needs to be vaccinated in order to begin moving past the pandemic that continues to wreak havoc in Latin America and beyond. While infection rates improved after first doses were administered, Covid-19 wasn’t properly controlled in the town until after a second shot was given. A complete study will be published soon.

India COVID-19 variant exhibits resistance; antibody drug shows promise
Antibody drugs and COVID-19 vaccines are less effective against a coronavirus variant that was first detected in India, according to researchers. The variant, known as B.1.617.2, has mutations that make it more transmissible. It is now predominant in some parts of India and has spread to many other countries. A multicenter team of scientists in France studied a B.1.617.2 variant isolated from a traveler returning from India. Compared to the B.1.1.7 variant first identified in Britain, the India variant was more resistant to antibody drugs, although three currently approved drugs still remained effective against it, they found. Antibodies in blood from unvaccinated COVID-19 survivors and from people who received both doses of the Pfizer/BioNTech vaccine were 3-fold to 6-fold less potent against the India variant than against the UK variant and a variant first identified in South Africa, according to a report posted on Thursday on the website bioRxiv ahead of peer review

UK now a risk to rest of Europe due to spread of Indian variant, scientists warn
The growing prevalence of the Indian coronavirus variant means the UK is now a risk to the rest of Europe and beyond, scientists have warned. France has already tightened its restrictions on British tourists due to the spread of the variant, announcing that anyone arriving from the UK must quarantine for seven days. A similar policy has been adopted in Germany, where, since 23 May, travellers from Britain have been banned from entering the country after the UK was designated a “virus variant area of concern” by the German public health institute.

German scientists claim they have figured out why some Covid vaccines cause blood clots
Germans scientists say they have figured out why the Covid vaccines from. AstraZeneca and Johnson & Johnson are linked to rare blood clots. In a new pre-print, the team says the problem is with the adenovirus vector, a common cold virus used to get the body to induce an immune response. They claim the vaccine is sent into the cell nucleus instead of surrounding fluid, where parts of it break off and create mutated versions of themselves. The mutated versions then enter the body and trigger the rare blood clots. Scientists say they can genetically adapt the vaccine to prevent the virus's spike proteins, which it uses to enter cells, from splitting apart

Vir, GSK win US nod for another COVID-19 antibody drug as rival falters
The Food and Drug Administration on Wednesday cleared a COVID-19 antibody treatment from Vir Biotechnology and partner GlaxoSmithKline for emergency use, making the drug, known as sotrovimab, the third of its kind available in the U.S.
As with similar treatments from Eli Lilly and Regeneron, the agency authorized Vir and GSK's drug for people who have mild-to-moderate symptoms of COVID-19, but are at high risk of worse outcomes due to age or underlying medical conditions. The drug reduced the risk of hospitalization or death in such patients by 85% in a Phase 3 trial that produced results in March. Vir's approval comes as coronavirus infections have receded in the U.S. amid a mass vaccination campaign, which could curtail demand for the drug. But the antibody might still prove useful, as lab tests have indicated sotrovimab retains its potency against virus variants that appear to erode the strength of some vaccines and antibodies.

Covid-19: Pfizer-BioNTech vaccine is “likely” responsible for deaths of some elderly patients, Norwegian review finds
The Pfizer-BioNTech covid-19 vaccine is “likely” to have been responsible for at least 10 deaths of frail elderly people in nursing homes in Norway, an expert review commissioned by the Norwegian Medicines Agency has concluded. The expert group was established at the end of February 2021 to look into the cause of the first 100 reported deaths of nursing home residents who had received the Pfizer-BioNTech vaccine. At the time, around 30 000 elderly nursing home residents had been vaccinated. Although the mortality rate in nursing homes is generally very high and the deaths of some nursing home residents after vaccination was anticipated, the Norwegian Medicines Agency wanted to determine whether the vaccine had possibly hastened any deaths and to gain a clearer understanding of the risks and benefits of its use in frail elderly people.

Tens of thousands of lives could have have been saved - top scientists back Dominic Cummings
Dominic Cummings’ central charge against the Government - that delays over imposing lockdowns led to tens of thousands of people dying from Covid-19 unnecessarily - was today backed up by two of Britain’s leading coronavirus experts. Professor John Edmunds, of the London School of Hygiene and Tropical Medicine, said a “very large number” of Covid-19 deaths could have been avoided in the second wave if the Government had taken more drastic action as being advised by scientists. In his damning evidence to a joint session of the Commons health and science committees, former No10 top adviser Mr Cummings said on Wednesday: “Tens of thousands of people died who did not need to die.”

GlaxoSmithKline, Vir snag FDA authorization for new COVID-19 antibody. But how will they sell it without a supply deal?
Following in the footsteps of Eli Lilly and Regeneron, a partnership between GlaxoSmithKline and Vir Biotechnology has won an emergency FDA nod for a COVID-19 antibody drug. The difference? It doesn’t have a supply deal with the U.S. government. Wednesday, the FDA issued (PDF) an emergency use authorization to GSK and Vir’s sotrovimab for mild-to-moderate COVID-19. Same as the previous go-aheads for similar therapies from Lilly and Regeneron, the new nod is limited to patients who aren’t hospitalized but are at high risk of progressing to severe disease. The anti-coronavirus antibody proved its worth in a phase 3 trial. The Comet-Ice study stopped early after an interim analysis found sotrovimab reduced the number of patients who died or needed hospitalization by 85% over placebo.

German researchers tie cold viruses used to deliver COVID-19 vaccine to rare blood clot risk
German researchers on Wednesday said that based on laboratory research, they believed they have found the cause of the rare but serious blood clotting events among some people who received COVID-19 vaccines made by AstraZeneca Plc and Johnson & Johnson. The researchers, in a study not yet reviewed by experts, said COVID-19 vaccines that employ adenovirus vectors - cold viruses used to deliver vaccine material - send some of their payload into the nucleus of cells, where some of the instructions for making coronavirus proteins can be misread. The resulting proteins could potentially trigger blood clot disorders in a small number of recipients, they suggest.

Covid-19: Variants are spreading in countries with low vaccination rates
With new daily covid-19 cases in steep decline across Europe and North America, and now falling in India, the curve of global daily mortality is trending downwards. But the virus continues to flare up, most recently in Cambodia, Malaysia, Singapore, Taiwan, Thailand, and Vietnam—countries often cited as models of pandemic control. Taiwan’s covid-19 death toll has more than doubled in one week—to 23 deaths in all. Having recorded just 135 locally acquired infections in the entire pandemic up to 14 May, Taiwan has since detected over 4000 cases as the country’s atrophied testing system struggles to keep up with new suspected cases. Covid testing had largely been abandoned even in cases of fever, such was the disease’s rarity in Taiwan. Case numbers have also surged in parts of South America, where mortality has been on a different scale of magnitude. Argentina has the world’s highest per capita death rate, having seen 493 deaths a day on average over the past week, or 10.8 deaths per million people per day, compared with 9.4 in Colombia, 8.8 in Brazil, and 1.6 in the US. Argentina’s toll this week was proportionally higher than the worst week seen in Colombia, Peru, or the US, though less deadly than the worst weeks in Brazil, Hungary, or the UK.

Mild, asymptomatic COVID-19 cases may be as infectious as severe ones
Only 8% of more than 25,000 German COVID-19 patients had high viral loads, one-third of whom were presymptomatic, asymptomatic, or mildly symptomatic, according to a study published yesterday in Science. High viral loads suggest greater infectiousness. Led by researchers from the Charite-Universitatsmedizin Berlin, the study involved measuring SARS-CoV-2 viral loads and estimating probability of virus cell culture isolation in 25,381 coronavirus patients, 24% of whom were identified at testing facilities, 38% of whom were hospitalized, and 6% of whom were infected with the B117 variant first seen in the United Kingdom.

In a Phase 2/3 trial of 3,732 children ages 12 to 17 in the United States, blood tests showed that the vaccine produced an immune response that was equivalent to earlier findings in adults. The trial wasn't designed to look specifically at efficacy. However, initial observations found that none of the children who received the vaccine got sick with Covid-19 starting 14 days after their second dose. Four of the children who received the placebo tested positive for Covid-19, which Moderna says is "consistent with a vaccine efficacy of 100%."

Explainer: What is 'black fungus' that is hitting India's COVID-19 patients?
A rapid rise in cases of mucormycosis, also known as black fungus, has added to the challenges faced by India's healthcare system as it deals with a massive second wave of COVID-19 infections. Mucormycosis is a fungal infection that causes blackening or discoloration over the nose, blurred or double vision, chest pain, breathing difficulties and coughing blood. The disease has a close link to diabetes, and conditions which compromise the immune system. Experts have said that an overuse during the COVID-19 pandemic of certain drugs which suppress the immune system could be causing the surge.

Coronavirus: so many variants, but vaccines are still effective
Viruses are constantly changing. This is because errors sometimes occur when they copy their genetic material. Some errors have no effect at all. Some might make the virus less viable. Some make it more benign, which means it can survive but doesn’t cause disease. The errors to watch for are those that might make the virus more infectious, or better able to avoid the immune system that is trying to counter them, either driven by natural infection or stimulated by a vaccine. SARS-CoV-2, the virus that causes COVID-19, is no different. Each time it divides, it rolls the dice, which could give rise to a more malign virus. This can happen anywhere, anytime. So it’s important to track variants and to see if they are spreading more easily from person to person, causing more mild or more severe disease, might avoid detection with current tests, or might respond less well to current treatments. Perhaps the biggest concern is breakthrough infections, where a fully vaccinated person still gets COVID.

CDC Ramps Up Research on Highly Contagious Variant from India
Federal Health officials are ramping up their surveillance of the highly transmissible Covid-19 variant first identified in India as experts warn that under-vaccinated areas in the U.S. could become hot spots for the mutation. While U.S. cases attributed to the B.1.617 variant currently sit below 1%, the growth rate remains unclear due to the small sample size. Meanwhile, one science group said the strain could be as much as 50% more transmissible than B.1.1.7, the variant that emerged from the U.K. That mutation was first seen in the U.S. in late December, and is now dominant nationally.

The new variant of concern has fundamentally changed the risk we face and therefore the government’s criteria for moving ahead with the road map have not been met, argue Stephen Reicher and colleagues. There are many things we know and many things we don’t know about the B.1.617.2 variant. We know that it is spreading fast (roughly doubling each week in the UK and nearly tripling last week from 520 to 1313 cases), that it is becoming established in a number of areas across the country, and that it is already the dominant variant in places such as Bedford, Bolton, and Blackburn.Compared to the dominant B.1.1.7 variant, we know that B.1.617.2 is very likely to be more transmissible and that it might be better able to transmit between people who are fully vaccinated

Long Covid symptoms ease after vaccination, survey finds
Covid-19 vaccines tend to alleviate the symptoms of long Covid, according to a large survey of more than 800 people that suggests mRNA vaccines, in particular, are beneficial. Though Covid-19 was initially understood to be a largely respiratory illness from which most would recover within a few weeks, as the pandemic wore on increasing numbers of people reported experiencing symptoms for months on end. There is no consensus definition of the condition of these people who have symptoms ranging from chronic fatigue to organ damage, let alone a standardised treatment plan. As vaccines hit the mainstream, concerns arose that vaccination could precipitate relapses or a worsening of symptoms. But conversely, anecdotal reports suggested that vaccines helped some people with long Covid.

Sanofi, GSK say revamped coronavirus vaccine is strong enough for final test
Sanofi and GlaxoSmithKline on Monday reported a coronavirus vaccine they developed together met the goal of a mid-stage clinical trial, boosting the companies' research efforts five months after an earlier version of the shot disappointed in a costly setback. Results from the trial, which enrolled 722 volunteers in the U.S. and Honduras, showed the revamped vaccine spurred immune responses that were comparable to what researchers have observed following naturally occurring cases of COVID-19. Importantly, the companies said responses were strong across age groups, including in older adults whose immune systems tend to be weaker. Sanofi and GSK now plan to launch a Phase 3 study of the vaccine in the "coming weeks" and expect to enroll some 35,000 adult volunteers from a "broad range of countries." Doing so will be harder than six months ago, however, after multiple other vaccines have been made available in many countries in North America, Europe and the Middle East.

Plasma from recovered patients found not helpful for COVID hospital patients
Convalescent plasma given to hospitalized COVID-19 patients did not improve survival or rates of release from the hospital within 28 days, need for invasive mechanical ventilation, or death, according to the most recent findings of the Randomised Evaluation of COVID-19 Therapy (RECOVERY) trial in the United Kingdom. The results, published late last week in The Lancet, add to evidence that SARS-CoV-2 antibody-rich plasma taken from COVID-19 survivors doesn't benefit severely ill coronavirus patients. The RECOVERY trial is evaluating several possible treatments for hospitalized COVID-19 patients at 177 National Health Services sites.

Italian study shows COVID-19 infections, deaths plummeting after jabs
COVID-19 infections in adults of all ages fell by 80% five weeks after a first dose of Pfizer, Moderna or AstraZeneca vaccine, according to Italian research published on Saturday. The first such study by a European Union country on the real-world impact of its immunisation campaign was carried out by Italy's National Institute of Health and the Ministry of Health on 13.7 million people vaccinated nationwide. Scientists started studying data from the day Italy's vaccination campaign began, on Dec. 27 2020, until May 3 2021. The analysis showed that the risk of SARS-CoV-2 infection, hospitalisation, and death decreased progressively after the first two weeks following the initial vaccination.

COVID mRNA vaccines induce immune response in pregnant, lactating women
COVID-19 mRNA vaccines trigger an immune response in pregnant and breastfeeding women, and maternal antibodies transfer into infant cord blood and breast milk, a small descriptive study yesterday in JAMA finds. A team led by Beth Israel Deaconess Medical Center researchers in Boston assessed immune response in a convenience sample of 103 pregnant, lactating, and nonpregnant women given either the Pfizer/BioNTech (54%) or the Moderna (46%) COVID-19 vaccine from December 2020 through March 2021. Seventeen percent of pregnant participants received their first vaccine dose in the first trimester, while 50% received it in their second trimester, and 33% got theirs in their final trimester.

COVID-19: Delaying second dose of coronavirus vaccine could cut deaths by up to 20%, study suggests
Delaying the second dose of a COVID vaccine so more people can get a first dose could cut deaths by up to 20%, a study suggests. The UK chose to use this strategy at the start of its rollout in December, with most people getting their second dose around 12 weeks after their first. That's despite a recommended interval of three weeks for the Pfizer jab and four to 12 weeks for the AstraZeneca vaccine. The peer-reviewed paper, published in the British Medical Journal, used a simulation model to test a daily rollout rate of 0.1%, 0.3% and 1% of the population.
Researchers found estimated deaths per 100,000 people fell from 442 to 402, 241 to 204, and 86 to 50 respectively - comparing standard dosing with a delayed strategy.

CureVac-GSK coronavirus variant vaccine generates good immune response in rats
A second-generation COVID-19 vaccine developed by CureVac and GlaxoSmithKline, designed to protect against coronavirus variants, produced a high level of immune response in a trial in rats, the companies said on Thursday. CureVac in February said it would team up with GlaxoSmithKline on a COVID-19 vaccine aimed at targeting several variants with one shot. The shot uses messenger RNA technology, similar to successful vaccines made by Pfizer-BioNTech and Moderna, and clinical trials of the shot in humans are expected to start in the third quarter of this year. The mRNA "backbone" of the shot differs from CureVac's first COVID-19 vaccine candidate, and it is designed to work well at lower doses.

Blood Expert Says He Found Why Some Covid-19 Vaccines Trigger Rare Clots
Scientists world-wide are racing to understand why Covid-19 vaccines from AstraZeneca and Johnson & Johnson are causing rare but potentially deadly blood clots. Determining the connection would help patients, doctors and health agencies better assess any risks posed by the vaccines and safely calibrate their use. In recent weeks, the U.S., the Canadian province of Ontario and several European countries including Norway and Denmark either paused or completely halted rollouts involving these vaccines. “Understanding the cause is of highest importance for the next-generation vaccines, because [the novel] coronavirus will stay with us and vaccination will likely become seasonal,” said Eric van Gorp, a professor at Erasmus University in the Netherlands who heads a group of scientists studying the condition.

Covid-19: Fever, chills, and aches more common when AstraZeneca and Pfizer vaccines are mixed, early data show
Mixing doses of the Oxford AstraZeneca and the Pfizer BioNTech covid-19 vaccine leads to more frequent mild to moderate reactions compared with standard dosing schedules, researchers have reported. Researchers running the University of Oxford led Com-COV study—which is investigating the reactogenicity and immunogenicity from mixing doses of the two vaccines—reported their preliminary results in a peer reviewed research letter in the Lancet. Matthew Snape, associate professor in paediatrics and vaccinology at the University of Oxford and chief investigator on the trial, said, “While this is a secondary part of what we are trying to explore through these studies, it is important that we inform people about these data, especially as these mixed doses schedules are being considered in several countries. “The results from this study suggest that mixed dose schedules could result in an increase in work absences the day after immunisation, and this is important to consider when planning immunisation of healthcare workers.”

England's coronavirus infections halved since March, study finds
The prevalence of coronavirus infections in England has halved since March helped by the swift rollout of vaccines, but new variants remain a threat, according to the findings of a closely watched survey released on Thursday. British Prime Minister Boris Johnson on Monday gave the green light to hugging and the serving of pints inside pubs from next week after months of strict restrictions as he set out the next phase of easing the pandemic lockdown. The REACT study, run by scientists at Imperial College London, found that the number of infections has fallen again with an average of only one in 1,000 people infected. "Today's findings demonstrate the impact our incredible vaccination rollout is having on COVID-19 infection rates across the country," said Matt Hancock, the health minister. "We're going in the right direction but with variants present, we must continue to exercise caution."

The ancestor of SARS-CoV-2’s Wuhan strain was circulating in late October 2019
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in a case from Wuhan, China, in December 2019, and subsequently became the cause of the coronavirus disease 2019 (COVID-19) pandemic that is ravaging the world today. A new study in the journal Molecular Biology and Evolution tracks its variants all over the world since the onset of the pandemic. Genomic sequencing has occurred using hundreds of thousands of viral genomic samples. The researchers used the best of these sequences to reveal how the virus has mutated and changed in different periods and regions of the pandemic.

Physics - A Recipe for Universal Vaccines
Just over a year ago, physicists around the world shifted their research efforts to the field of infectious diseases to help combat the COVID-19 pandemic. In the US, soft-matter physicists trialed a technique for detecting SARS-CoV-2, the virus that causes COVID-19; in Switzerland, high-energy physicists tested an inexpensive ventilator technology that could help sufferers breathe; and in the UK, condensed-matter physicists donated their personal and protective equipment to the country’s hospitals. Applying the tools of physics to infectious diseases is an old idea, however, as physicists have worked for decades on understanding how diseases spread and how viruses evolve. Arup Chakraborty of the Massachusetts Institute of Technology is one such physicist. He and his postdoc Raman Ganti now present results of their recent project to use statistical-mechanics methods to predict the characteristics of the optimal antigens for “universal” vaccines for rapidly mutating viruses, such as influenza. Their insights should also be applicable to creating broad-coverage vaccines for a range of viruses from HIV to SARS-CoV-2. “Vaccinations have saved more lives than any other medical procedure,” Chakraborty says. “Nonetheless, effective vaccines do not exist for highly mutable pathogens—that’s why we need a seasonal flu shot. Now that COVID-19 is mutating, we could end up needing repeated vaccinations for that virus too.”

COVID Variants and a Third Wave: Scientists Warn Government Is 'Sleepwalking into Disaster'
The Scientific Advisory Group on Emergencies (SAGE) has warned that, if the Government fails to contain new Coronavirus variants of concern, it could lead to a third wave of the pandemic three times as large as the second wave, documents released this week reveal. If this occurs, it could necessitate a third lockdown despite the success of the vaccine programme. Several top scientists have also warned that the new Indian variant could already have become the dominant form of COVID-19 in Britain, with the potential to cause infections in spite of vaccinations. According to Professor Ravindra Gupta, of the Cambridge Institute of Therapeutic Immunology and Infectious Disease, the Indian variant “likely will cause infections despite vaccination and we don’t know how big that problem will be”. Despite these sober warnings, newspapers such as The Times and Daily Mail have obfuscated SAGE’s analysis by selectively reporting its new scientific findings and omitting to inform readers of the huge risks and uncertainties posed by new variants.

A potential new vaccine developed by members of the Duke Human Vaccine Institute has proven effective in protecting monkeys and mice from a variety of coronavirus infections -- including SARS-CoV-2 as well as the original SARS-CoV-1 and related bat coronaviruses that could potentially cause the next pandemic. The new vaccine, called a pan-coronavirus vaccine, triggers neutralizing antibodies via a nanoparticle. The nanoparticle is composed of the coronavirus part that allows it to bind to the body's cell receptors and is formulated with a chemical booster called an adjuvant. Success in primates is highly relevant to humans.

The coronavirus that causes Covid-19 has mutated more than 6600 times
The Sars-CoV-2 virus that sparked the Covid-19 pandemic has undergone more than 6,600 unique spike protein mutations, said Dr Sebastian Maurer-Stroh, executive director of the Bioinformatics Institute at the Agency for Science, Technology and Research (A*Star). Viruses mutate whenever there is a "mistake" in the replication process. This could result from an addition, a deletion or a change to its genetic code. If that mistake increases its survival prospects, more copies of that "wrong" replication will survive, and sometimes overwhelm the original version. For example, the D614G mutation which started to rise sharply in February last year is now found in all samples of the virus, no matter which variant they are.
Because this variant became so pervasive, it was given a clade name - or family group - of its own, and is designated as G clade. The World Health Organisation (WHO) says that while the G clade has increased infectivity and transmission, the illness it causes is not more severe, nor does it affect diagnostics, treatment or vaccines.

Why mixing vaccines could help boost immunity
A handful of trials are now under way to test the power of vaccine combinations, with the first results due in later this month. If these mixed regimens prove safe and effective, countries will be able to keep the vaccine rollout moving even if supplies of one vaccine dwindle because of manufacturing delays, unforeseen shortages, or safety concerns. But there’s another, more exciting prospect that could be a vital part of our strategy in the future: mixing vaccines might lead to broader immunity and hamper the virus’s attempts to evade our immune systems.

Indian Covid variant is ‘of concern’, says Public Health England
A coronavirus variant first detected in India has been designated a “variant of concern” by England’s public health body, as consternation about its spread within communities grows. The variant, called B.1.617.2 is one of three closely related variants that were first detected in India and have since been found in the UK, with the others known as B.1.617.1 and B.1.617.3. These variants have worried scientists as they have mutations in their spike protein that it is thought may help the virus to evade the body’s immune responses and be more transmissible. The variant B.1.617.2, also known as VOC-21APR-02, has caused particular consternation as its numbers have risen rapidly in the UK.

"We want to hope for the best, and prepare for the worst," CDC director Dr. Rochelle Walensky told actress Jennifer Garner in an interview streamed on Instagram. More than a third of the US is fully vaccinated against coronavirus, but it's still short of the benchmark of 70% to 85% of the total population that needs to be immune -- through vaccination or previous infection -- to control its spread. And many yet to receive the vaccine are those who have not decided whether they want it or have decided against it.

Moderna vaccine booster 'effective against Covid variants in trials'
Moderna's tweaked coronavirus vaccine has been found to neutralise both the Brazil and South Africa variants in laboratory trials. The company behind the jab announced that a single dose of one of its vaccines given as a booster to previously vaccinated people increased neutralising antibody titer responses against SARS-CoV-2 and both the South Africa and Brazil variants. The currently authorised Moderna Covid-19 vaccine is mRNA-1273 which was developed to protect against the ancestral strain of the virus first identified in Wuhan, China, while mRNA-1273.351 was developed to protect against the B.1.351 virus first identified in South Africa. Moderna said a booster dose of mRNA-1273.351 achieved higher neutralising antibody titers against the South Africa variant than a booster dose of mRNA-1273. The initial data is from a study involving 40 people.

The follow-up after 35 days found the vaccine was generally well-tolerated in teens, and no serious safety concerns were identified, a press release from Moderna on Thursday stated. “An initial analysis of 3,235 participants showed a vaccine efficacy rate of 96% in participants who received at least one injection. The analysis included 12 cases starting 14 days after the first dose and based on the United States’ Centre for Disease Control and Prevention’s definition of the coronavirus,” the statement read. It added that, because the incidence rate of Covid-19 is lower in adolescents, the case definition is less strict than that for the trials of adults, resulting in vaccine efficacy against milder cases of the virus.

Covid-19 herd immunity is a difficult target, experts warn, but vaccinating teens could be key to protecting us this fall
The United States is offering up freebies, expanding the pool of those eligible and shifting access to local pharmacies in its attempts to encourage vaccine holdouts to get inoculated against Covid-19. In the last six months, nearly 150 million people in the US have received at least one dose of a Covid-19 vaccine in what is the fastest and largest mass vaccination effort in world history. Still, the US vaccination rate has declined from its peak last month, pushing officials to offer new incentives, known as carrots, to further encourage the wary, hesitant and inaccessible to get vaccinated. Some of those carrots are access to cultural events.

Giving 2 Doses Of Different COVID-19 Vaccines Could Boost Immune Response
Typically, if you get a COVID-19 vaccine that requires two doses, you should get two of the same vaccine. Two Pfizer shots, or two Moderna shots. Not one and then the other. But in the future, that could change, either by necessity or by design.
This idea of using two types of vaccines isn't a new concept. It's known as heterologous vaccination, although there's a more colloquial term. "In the U.K. at the moment, we're sort of calling it 'mix and match,' " says Helen Fletcher, a professor of immunology at the London School of Hygiene & Tropical Medicine. She says shortages of a vaccine or concerns about side effects may induce health officials to adopt a mix-and-match strategy.

Tweaked Moderna vaccine ‘neutralises Covid variants in trials’
The first “tweaked” vaccine against the worrying coronavirus variants that emerged in South Africa and Brazil has successfully neutralised them in laboratory trials, the US company Moderna has said. The results of the small trial suggest that boosters against the variants will be feasible and could be rolled out this year to counter the threat from variants that have appeared around the world and are feared in some cases to be more transmissible or partially vaccine-resistant. Leading companies have been racing to produce adapted versions of their Covid vaccines. Pfizer/BioNTech, which has a similar mRNA vaccine to Moderna’s, and Oxford/AstraZeneca are also in the process of developing tweaked vaccines against the South African variant, B1351, and the Brazilian variant, P1, which appear to be the major threat to current immunisation programmes.

Booster shots rev up immune response to coronavirus variants, Moderna says
A booster shot of Moderna's coronavirus vaccine revs up the immune response against two worrying coronavirus variants, the company reported Wednesday. And a booster dose formulated specifically to match the B.1.351 variant first seen in South Africa was even more effective, Moderna said in a statement.
Vaccine makers are trying to get out ahead of the new variants and the design of the new mRNA vaccines made by Moderna and Pfizer make this easier than it would have been in the past. The genetic material used as the basis of the vaccines is made in a lab and the sequence is easily tweaked.

Antibody drug neutralizes virus variants in lab study; COVID-19 antibodies detectable 12 months after infection
An experimental monoclonal antibody treatment for COVID-19 being developed by Eli Lilly and Co (LLY.N) and AbCellera Biologics Inc (ABCL.O) can "potently" neutralize numerous coronavirus variants, including those first identified in the UK, Brazil, South Africa, California and New York, scientists have found in test tube experiments. The antibody - known as LY-CoV1404 or LY3853113 - works by attaching itself to a place on the virus that has shown few signs of mutating, which means the drug is likely to retain its effectiveness over time, the researchers said in a report posted on Friday on bioRxiv ahead of peer review.

Do people who have had COVID-19 need a second vaccine shot?
A new study suggests that there is a strong boost to the immunity of everyone who receives the first dose of an mRNA vaccine, including those who have previously had a SARS-CoV-2 infection. However, only people who have never had a SARS-CoV-2 infection appeared to benefit from the second dose. The scientists tracked not only antibody responses to vaccination but also the creation of memory B cells, which provide longer lasting immunity against infection. People who experienced particularly negative side effects from the vaccine — such as fever, headache, and muscle pain — had stronger immune responses.

Access to mental health services dwindled as pandemic need strained providers: GAO report | TheHill
Access to mental health services dwindled as providers were strained and under the demand for care during the COVID-19 pandemic, according to a Government Accountability Office (GAO) report made public on Friday.
The GAO concluded that the number of people experiencing anxiety, depression and drug overdoses heightened during the pandemic, while mental health professionals dealt with layoffs, decreased hours and having to turn away patients.
Respondents to Centers for Disease Control and Prevention (CDC) surveys determined that about 38 percent reported symptoms of anxiety or depression between April 2020 and February 2021. Eleven percent said the same in 2019.
Similarly, emergency departments saw 36 percent more visits for overdoses and 26 percent more visits for suicide attempts from mid-March to mid-October of last year, compared to the previous year.

One vaccine shot leaves many vulnerable to Covid variants, UK study finds
Individuals who receive one shot of the Covid-19 vaccine and have never been infected by the virus could be very vulnerable to new variants, according to a new UK study. Researchers from Imperial College London, Queen Mary University of London and University College London looked at immune responses in healthcare workers who had received one shot of the BioNTech/Pfizer vaccine. The scientists found that people who had not previously been infected by Covid-19 showed very low levels of neutralising antibodies against the original strain from Wuhan, the B.1.1.7 variant first identified in Kent and B.1.351 from South Africa. By contrast, those who had previously had mild or asymptomatic infection and then received a single dose appeared to have greatly enhanced protection against both B.1.1.7 and B.1.351, demonstrating high neutralising antibodies and a strong response by T cells, which remember past infection.

Prior SARS-CoV-2 infection boosts response to variants after first vaccine dose
A single dose of vaccine boosts protection against SARS-CoV-2 coronavirus variants, but only in those with previous COVID-19, a study has found. In those who have not previously been infected and have so far only received one dose of vaccine the immune response to variants of concern may be insufficient. The findings, published today in the journal Science and led by researchers at Imperial College London, Queen Mary University of London and University College London, looked at immune responses in UK healthcare workers at Barts and Royal Free hospitals following their first dose of the Pfizer/BioNTech vaccine.* They found that people who had previously had mild or asymptomatic infection had significantly enhanced protection against the Kent and South Africa variants, after a single dose of the mRNA vaccine. In those without prior COVID-19, the immune response was less strong after a first dose, potentially leaving them at risk from variants.

Vaccine protects COVID-19 survivors against variants In COVID-19 survivors, the Pfizer/BioNTech (PFE.N), mRNA vaccine protects not only against the original virus strain but also against worrisome variants, two studies show. UK researchers analyzed immune responses after a single dose of the vaccine in 51 people, including 25 people previously infected with an early version of the novel coronavirus. Survivors showed enhanced antibody responses against the newer, more infectious variants first seen in the UK and South Africa, whereas people who had not previously been infected did not produce antibodies that could neutralize the variants, according to a report on Friday in Science.

Tackling the rise of concerning COVID-19 variants in the UK
Variants that are considered to have concerning epidemiological, immunological or pathogenic properties, as well as evidence of community transmission in the UK or abroad, are first designated as a VUI. After being risk assessed by the relevant expert committee, a VUI may be upgraded to VOC. The first VOC — B.1.1.7 — was detected in Kent in September 2020 and is now the dominant lineage in the UK. It has also been detected in more than 100 countries around the world. A similar variant with an additional mutation — B.1.1.7 + E484K — was detected in Bristol in December 2020 and is also circulating in the UK but at very low levels, with no new cases reported since 1 March 2021. Two further VOCs have been identified in the UK — one first detected in South Africa and one first detected in Japan (in a traveller from Brazil). To date, there are relatively small numbers of cases in the UK with only isolated pockets of community transmission. Identified cases are being tackled aggressively through surge testing — increased testing and enhanced contact tracing in specific locations — and genomic sequencing.

COVID-19 variants spread faster but grew milder over time in Ohio
Cleveland Clinic researchers identified 484 unique mutations among six strains of SARS-CoV-2 isolates early in the COVID-19 pandemic, finding that the first variants were more deadly than subsequent strains and suggesting that monitoring circulating strains may help predict patient outcomes. Their study, published yesterday in JAMA Network Open, involved sequencing the viral genomes from specimens obtained from 302 COVID-19 patients at Cleveland Clinic from Mar 11 to Apr 22, 2020, and comparing them with those of the original SARS-CoV-2 strain from Wuhan, China. Infection with early virus subgroups, or clades, was associated with higher death rates than later strains (21.4% vs 5.6%). "These findings help explain persistent hospitalization yet decreasing mortality as the pandemic progresses," the authors wrote. "SARS-CoV-2 clade assignment is an important factor that may aid in estimating patient outcomes."

Covid-19: One dose of vaccine cuts risk of passing on infection by as much as 50%, research shows
Adults infected with covid-19 three weeks after receiving one dose of the Pfizer-BioNTech or Oxford-AstraZeneca vaccine were 38-49% less likely to pass the virus on to their household contacts than people who were unvaccinated, a preprint released by Public Health England has shown.The research looked at the proportion of household contacts who tested positive 2-14 days after vaccinated index cases, comparing this with households where the index case was unvaccinated. The team said that protection was seen from around 14 days after vaccination, and similar levels were observed regardless of the age of cases or contacts. Public Health England said that this protection was on top of the reduced risk of a vaccinated person developing symptomatic infection in the first place, which was around 60-65% four weeks after one dose of either vaccine. “This is very promising,” said Deborah Dunn-Walters, the British Society for Immunology’s covid-19 taskforce chair and professor of immunology at the University of Surrey. “While this study brings welcome news, we must not be complacent . . . It is still very important for us all to get two doses of the covid-19 vaccine to ensure we receive the optimal and longest lasting protection, both for ourselves and our communities.”

BioNTech expects vaccine trial results for babies by September
BioNTech expects results by September from trials testing the COVID vaccine it developed with Pfizer on babies as young as six months old, German magazine Spiegel cited the company’s CEO as saying. “In July, the first results could be available for the five-to-12-year-olds, in September for the younger children,” BioNTech Chief Executive Ugur Sahin told Spiegel. He added it takes about four to six weeks to evaluate the data. “If all goes well, as soon as the data is evaluated, we will be able to submit the application for approval of the vaccine for all children in the respective age group in different countries,” he said. BioNTech and Pfizer asked US regulators this month to approve the emergency use of their vaccine for adolescents aged 12 to 15. Sahin was quoted by Spiegel as saying the company was “in the final stages before submission” to European regulators for children aged 12 and older. A trial published at the end of March found the companies’ COVID-19 vaccine was safe, effective and produces robust antibody responses in adolescents.

Vaccine cuts the risk of passing on coronavirus by half
Vaccinated people are nearly 50 per cent less likely to pass on the virus even if they are unlucky enough to become infected, a study has found. The findings are the most convincing demonstration so far that, on top of blocking most infections in the recipient, vaccines also have a strong effect on transmission — raising hopes that a severe summer wave can be avoided as the country opens up. “This is terrific news — we already know vaccines save lives, and this study is the most comprehensive real-world data showing they also cut transmission of this deadly virus,” Matt Hancock, the health secretary, said.

Why The COVID-19 Variants Spreading in India Are a Global Concern
As the numbers of COVID-19 cases and deaths in India continue to mount, public health officials are carefully watching yet another looming threat: the appearance of mutations that could be making the virus circulating there more infectious or more capable of causing severe disease. Scientists believe that the variants of SARS-CoV-2 responsible for this second wave of cases in India already include at least two mutations that make them more dangerous. These mutations are already familiar to COVID-19 experts. One is found in a variant first identified in South Africa, while the other is part of a variant believed to have emerged from California. Researchers believe that these two mutations may, respectively, make it easier for the virus to infect human cells, and to evade the protection provided by immune cells like antibodies. According to the latest data from the public genome database GISAID, 38% of genetically sequenced samples from India collected in March contain the two mutations—scientists have labelled this the B.1.617 variant.

Calls for 4,000 UK volunteers for latest coronavirus vaccine study
Researchers are recruiting 4,000 volunteers to take part in a study trialling a new coronavirus vaccine. Developed by Valneva, the jab is being manufactured at the company’s site in Livingston, West Lothian. It is the only inactivated, adjuvanted (an ingredient to create a stronger immune response) Covid-19 vaccine in clinical development in Europe. Inactivated vaccines have been used over the last 100 years to vaccinate billions of people – including for seasonal flu, hepatitis A, polio and rabies. After positive safety and immunogenicity study results from the first two phases of the trial, which showed the study vaccine dose was “well tolerated with no safety concerns identified”, recruitment to the final phase two/three stage of the study will start in the final week of April. The study will run across 22 National Institute for Health Research (NIHR) sites in England, and two devolved administration sites in Scotland. It is open to healthy adults who have not had a previous Covid-19 vaccine.

Scientists from Manchester University have discovered that patients are up to three times more likely to test positive for Covid 19 in hospital if they were shift workers during their career. Researchers used data from UK Biobank - the world’s largest biomedical database. It showed that shift work increased the likelihood of testing positive for COVID-19 in hospitalised patients 2-3 fold, depending on the nature of shift work. Though there are several known risk factors for COVID-19, they do not always explain why COVID-19 outbreaks happen in factories or healthcare settings which is why they investigated the role of shift work.

Is a Cheap 'Universal' Coronavirus Vaccine on the Way?
An experimental COVID-19 vaccine could potentially provide universal protection against future COVID variants as well as other coronaviruses — maybe even the ones responsible for the common cold. And it's dirt cheap — less than $1 a dose, researchers say. The vaccine targets a part of the COVID virus' spike protein that appears to be highly resistant to mutation and is common across nearly all coronaviruses, said senior researcher Dr. Steven Zeichner. He is a professor of pediatric infectious disease with the University of Virginia, in Charlottesville. In animal studies, the COVID vaccine protected pigs against two separate diseases caused by two types of coronavirus, COVID-19 and porcine epidemic diarrhea virus (PEDV), according to results published online recently in the Proceedings of the National Academy of Sciences.

With OK from experts, some states resume use of J&J vaccine
With a green light from federal health officials, many states resumed use of the one-shot Johnson & Johnson coronavirus vaccine on Saturday. Among the venues where it was being deployed: the Indianapolis Motor Speedway. Among the other states ordering or recommending a resumption, along with Indiana, were Arizona, Colorado, Connecticut, Louisiana, Maine, Massachusetts, Michigan, Missouri, Nevada, New York, Tennessee, Texas and Virginia. Those moves came swiftly after U.S. health officials said Friday evening that they were lifting an 11-day pause on vaccinations using the J&J vaccine. During the pause, scientific advisers decided the vaccine’s benefits outweigh a rare risk of blood clot. “The state of New York will resume administration of this vaccine at all of our state-run sites effective immediately,” Gov. Andrew Cuomo said in a statement Saturday morning.

Vaccines Are Effective Against the New York Variant, Studies Find
For weeks, New Yorkers have witnessed the alarming rise of a homegrown variant of the coronavirus that has kept the number of cases in the city stubbornly high. City officials have repeatedly warned that the variant may be more contagious and may dodge the immune response. On that second point, at least, they can now breathe easier: Both the Pfizer-BioNTech and Moderna vaccines will effectively prevent serious illness and death from the variant, two independent studies suggest. Antibodies stimulated by those vaccines are only slightly less potent at controlling the variant than the original form of the virus, both studies found.

Students and staff will be offered weekly tests using lateral flow devices (LFDs). Half the participating schools will then offer daily tests to students who have come into close contact with known Covid-19 sufferers, to enable them to avoid quarantine, while the rest — the control group — will make such students quarantine for 10 days. Researchers involved in the study hope the research will prove that the tests can effectively pick up cases of infectious disease, providing evidence to counter the pervasive scepticism surrounding the value of LFDs, which have been rolled out in large numbers since late last year.

COVID-19 vaccines: building and maintaining confidence
As COVID-19 vaccines are rolled out globally, the AstraZeneca vaccine (Vaxzevria) continues to be marred in controversy, from its slow and still awaited approval by the US Food and Drug Administration amid concerns about paucity of large-scale trial data from the USA, to safety alerts around the development of rare blood clotting events coupled with thrombocytopenia, particularly cerebral venous sinus thrombosis (CVST) and splanchnic vein thrombosis (SVT). As of April 4, 2021, 169 cases of CVST and 53 cases of SVT have been reported in the European Economic Area and the UK after the administration of 34 million vaccines.

Yes, vaccines block most transmission of COVID-19
COVID-19 vaccines have provided an opportunity to slow the spread of the virus and end the pandemic. Now scientists are trying to learn just how much the vaccines can prevent transmission from occurring at all. New data from the CDC shows that COVID-19 infections do occur in vaccinated people, but they appear exceptionally rare. More than 10 million people in the United Kingdom have now been fully vaccinated against COVID-19. In the United States, that figure is 85 million people. As of April 14, the Centres for Disease Control and Prevention had received reports that 5,814 fully vaccinated people had developed COVID-19 infections in the U.S. Nearly half of these infections (45 percent) were in people at least 60 years old. Seven percent of people with breakthrough infections—infections that occur after complete vaccination—were hospitalised and one percent died.

How long does protection from COVID-19 vaccines last?
How long does protection from COVID-19 vaccines last? Experts don’t know yet because they’re still studying vaccinated people to see when protection might wear off. How well the vaccines work against emerging variants will also determine if, when and how often additional shots might be needed. So far, Pfizer’s ongoing trial indicates the company’s two-dose vaccine remains highly effective for at least six months, and likely longer. People who got Moderna’s vaccine also still had notable levels of virus-fighting antibodies six months after the second required shot.

Double masking amid COVID-19 not backed by research, experts say
A study concluding that wearing a disposable medical procedure mask under a reusable cloth face covering protects the wearer against COVID-19 infection better than a mask alone has some scientists worried that it could inadvertently lead to a false sense of security, risky behaviors, and infections. The study, one of a series on pandemic face coverings funded partially by the Centers for Disease Control and Prevention (CDC), was published on Apr 16 in JAMA Internal Medicine. The CDC used the studies as a basis for its Apr 6 updated face covering guidelines, which call for the use of a multilayered cloth mask or a disposable mask under a cloth mask to press the edges of the disposable mask against the face.

Roche looking for new place to test COVID-19 pill after cases plummet in UK
Roche (ROG.S)is looking for another location to carry out trials of its pill to fight COVID-19, after plummeting case numbers in Britain made it difficult to find enough patients for its study there, the Swiss drugmaker said on Wednesday. Roche and Boston-based partner Atea Pharmaceuticals (AVIR.O) are hoping their AT-527 pill could offer an anti-viral therapy to treat COVID-19 patients that would be easier to administer and cheaper than other prospective treatments, such as antibody cocktails or Gilead Science's (GILD.O) remdesivir. In an interview in Swiss media in early March, Roche Chairman Christoph Franz had offered the tantalizing prospect of data on AT-527 "within the next weeks", saying he dreamed of being able to fight the pandemic with a pill by year's end.

Link between cardiac arrests and COVID may help map the pandemic
A new study, published this month, collected data from 50 US cities as well as from major cities in the United Kingdom, France, Italy, New Zealand and Australia. The study showed that rises in out-of-hospital cardiac arrests were linked to rising COVID cases. The study was based on data provided by the Metropolitan EMS Medical Directors Global Alliance, a surveillance network of emergency medical services (EMS) staff who voluntarily share data. Dr Paul Pepe is global coordinator of the alliance and also a co-author of the study. He told Al Jazeera that normally a 10 percent increase in cardiac arrests would be a cause for concern. But during last spring in the US, two-thirds of US cities in the study saw increases between 20 and 50 percent. In cities particularly hit hard, the rate doubled

Racial minorities at higher risk for COVID-19 hospitalization, ICU care
Racial minority COVID-19 patients are at much higher risk for needing hospitalization and intensive care than their White counterparts, a new Kaiser Permanente Southern California (KPSC) study finds. The retrospective study, published yesterday in the Annals of Internal Medicine, involved comparing the electronic health records of 47,974 adult Hispanic, Black, Asian, Pacific Islander, and White COVID-19 patients from Mar 1 to Jul 31, 2020. The researchers saw disparities by race for all outcomes, even after adjustment for age, sex, underlying medical conditions, and body mass index (BMI). Racial minorities had a slightly higher chance than White patients of being tested for or diagnosed as having COVID-19 but were also at substantially higher risk for hospitalization and ICU care

‘No one was listening’: Long Covid patients struggle to get care for their symptoms
Thousands of people with long Covid have struggled to receive medical care for their symptoms. Many have found that even if they’re able to see a doctor, it can be difficult to be heard, and the best treatments remain unclear. Medical centers across the country are opening clinics specifically for people with lingering Covid symptoms, aiming to harness the expertise of specialists ranging from pulmonologists to physical therapists to neurologists. But many long Covid sufferers are located far from such a clinic, and the waitlist to be seen often is long. For example, the Cleveland Clinic’s post-Covid recovery center, reCOVer clinic, welcomed 113 patients in its first month, and as of mid-March, the clinic’s next available appointments were at the end of July. Penn Medicine’s Post-Covid Assessment and Recovery Clinic in Philadelphia has enrolled 458, with a three-month waitlist for new patients.

Blood Clotting Risk Higher for COVID-19, Than From Vaccines
Researchers at the University of Oxford in England reported that the risk of the rare blood clotting known as cerebral venous thrombosis (CVT) following COVID-19 infection is around 100 times greater than normal. And several times higher than it is post-vaccination or following influenza. The study authors, led by Professor Paul Harrison and Dr. Maxime Taquet, counted the number of CVT cases diagnosed in the two weeks following diagnosis of COVID-19 or after the first dose of a vaccine. They then compared these to calculated incidences of CVT following influenza infection and the background level in the general population. These researchers report that CVT is more common after COVID-19 than in any comparison groups, with 30% of these cases occurring in the under 40 population.

First study into prevalence of COVID-19 symptoms amongst high-risk children
Children with weakened immune systems have not shown a higher risk of developing severe COVID-19 infection despite commonly displaying symptoms, a new study suggests. During a 16-week period which covered the first wave of the pandemic, researchers from the University of Southampton and University Hospital Southampton carried out an observational study of nearly 1500 immunocompromised children – defined as requiring annual influenza vaccinations due to underlying conditions or medication. The results, published in BMJ Open, showed that symptoms of COVID-19 infection were common in many of the children – with over two thirds of participants reporting at least one symptom and one third experiencing three or more symptoms simultaneously. One hundred and ten patients with symptoms undertook viral PCR tests, none of whom tested positive.

Scientists from the National Institutes of Health (NIH) in the U.S. and the University of Plymouth in the U.K. found that MK-4482, also called Molnupiravir, was effective when provided up to 12 hours before or 12 hours after infection with SARS-CoV-2, the novel coronavirus that causes COVID-19. The drug can also decrease damage it causes to lungs, states the study conducted on hamsters.

J&J to resume rollout of COVID-19 vaccine in Europe with safety warning
Johnson & Johnson (JNJ.N) said on Tuesday it will resume rolling out its COVID-19 vaccine in Europe after the region’s medical regulator said the benefits of the shot outweigh the risk of very rare, potentially lethal blood clots. Europe’s health regulator, the European Medicines Agency (EMA), on Tuesday recommended adding a warning about rare blood clots with low blood platelet count to the vaccine’s product label and said the benefits of the one-dose shot outweigh its risks.

First Covid-19 vaccination protects blood cancer patients, study suggests
A single dose of a coronavirus vaccine triggers an immune response in around 70% of patients with the blood and bone marrow cancer, myeloma, according to a new study. Researchers say the findings suggest the jab could provide protection against the virus. Experts tested for Covid-19 coronavirus antibodies in 93 people with myeloma. A recent report with a smaller number of patients with the cancer suggested that blood cancer patients might receive limited protection after vaccination. Myeloma is a cancer of the immune cells produced in the bone marrow, and puts patients at greater risk of severe Covid-19 infection.

Volunteers to be reinfected with Covid-19 to help improve vaccines
Volunteers who have recovered from a coronavirus infection will be deliberately infected with the virus for a second time, in a new study which could help develop new treatments and vaccines against the disease. The study, led by a team from the University of Oxford, will investigate how a previous infection affects a second exposure to the virus and what kind of immune response is needed to protect people. It is known that some Covid-19 survivors have gone on to become reinfected at a later stage, and as variants of the virus emerge with new mutations the risk to the success of vaccines and natural protection could be significant.

British scientists on Monday launched a trial which will deliberately expose participants who have already had COVID-19 to the coronavirus again to examine immune responses and see if people get reinfected. In February, Britain became the first country in the world to give the go-ahead for so-called "challenge trials" in humans, in which volunteers are deliberately exposed to COVID-19 to advance research into the disease caused by the coronavirus. The study launched on Monday differs from the one announced in February as it seeks to reinfect people who have previously had COVID-19 in an effort to deepen understanding about immunity, rather than infecting people for the first time.

South African variant may 'break through' Pfizer vaccine protection, but vaccine highly effective, Israeli study says
The coronavirus variant discovered in South Africa can break through the protection provided by Pfizer Inc and BioNTech's COVID-19 vaccine to some extent, a real-world data study in Israel found. However, the variant's prevalence in Israel is very low and the vaccine remains highly effective. The study was released on the medRxiv pre-print site on April 9 and has not been peer reviewed. It compared almost 400 people who had tested positive for COVID-19, after they received one or two doses of the vaccine, against the same number of unvaccinated patients with the disease. It matched age and gender, among other characteristics.

The Covid-19 Plasma Boom Is Over. What Did We Learn From It?
Scott Cohen was on a ventilator struggling for his life with Covid-19 last April when his brothers pleaded with Plainview Hospital on Long Island to infuse him with the blood plasma of a recovered patient. The experimental treatment was hard to get but was gaining attention at a time when doctors had little else. After an online petition drew 18,000 signatures, the hospital gave Mr. Cohen, a retired Nassau County medic, an infusion of the pale yellow stuff that some called “liquid gold.” In those terrifying early months of the pandemic, the idea that antibody-rich plasma could save lives took on a life of its own before there was evidence that it worked.

EMA starts review of GSK's monoclonal antibody to treat COVID-19 patients
The European Medicines Agency said on Thursday it is reviewing available data on the use of GlaxoSmithKline's monoclonal antibody to treat COVID-19 patients.
The agency said its review of VIR-7831, which GSK is developing with Vir Biotechnology Inc, will include data from a study comparing its effect with that of a placebo in patients with mild to moderate COVID-19 who were at high risk of progressing to a more severe condition. While a more comprehensive rolling review is expected to start at a later time, the agency said the current review will provide European Union-wide recommendations for national authorities who may take decisions on early use of the medicine. The companies reported in March that VIR-7831 reduced the risk of hospitalisation and deaths among patients by 85%, based on interim data from a study.

Severe Covid-19 risk with asthma and COPD lower than previously thought
The risk for people with asthma and other chronic respiratory diseases of severe Covid-19 is not as high as had been feared at the start of the pandemic, say researchers from the University of Oxford. Analysis of records from 8 million patients at 1,205 general practices in England found people with active asthma and severe asthma had 26% and 29% higher relative risks of hospital admission with Covid-19 and around 30% higher relative risk of admission to intensive care compared with matched patients with no underlying respiratory disease. However, this is lower than suggested by data collected between January and April 2020, which showed that COPD was associated with a 50% increased risk of hospitalisation and 54% increased risk of death from Covid-19. Furthermore, there was no evidence that asthma was associated with an increased absolute risk of death from Covid-19, and the risks appeared similar for all ethnicities, the researchers reported in The Lancet Respiratory Medicine.

Covid-19: Single dose of Pfizer or AstraZeneca vaccine produces strong antibody response in over 80s
A single dose of the Pfizer or Oxford-AstraZeneca covid-19 vaccine produces equivalent antibody responses five weeks after vaccination, a small study looking at people over 80 has found. The study, led by University of Birmingham researchers and made available through a preprint, found that antibodies specific to the SARS-CoV-2 spike protein were present in most people in both groups—93% after the Pfizer vaccine and 87% after the AstraZeneca vaccine. Researchers have said that these findings are “reassuring” for countries that decided to delay second doses in favour of vaccinating more people with a first dose. In the UK, people over 80 were in the first priority group for vaccination and received either the Pfizer or AstraZeneca vaccine. At the end of December 2020, the UK chief medical officers announced that the second doses of the covid vaccines should be given towards the end of 12 weeks rather than after the previously recommended 3-4 weeks.
The research team collected blood samples from 165 people aged 80 to 99 years and living independently 5-6 weeks after their first vaccine dose. Of these, 76 received the Pfizer vaccine and 89 received the AstraZeneca vaccine. They then used a range of assays to measure the immune response generated. A small number of people (eight) had signs of previous natural covid-19 infection. Compared with those without previous infection, their antibody and T cell responses after the first vaccine dose were significantly higher (691-fold and fourfold, respectively). The study also found stronger T cell responses in people who had received the AstraZeneca vaccine, with 31% of this group producing detectable T cell responses compared with 12% of the Pfizer-BioNTech vaccine group.

UK scientists find higher risk of brain clots from COVID-19 compared with vaccines
There is a much higher risk of brain blood clots from COVID-19 infection than there is from vaccines against the disease, British researchers said on Thursday, after the rollout of inoculations was disrupted by reports of rare clots. AstraZeneca (AZN.L) and Johnson & Johnson (JNJ.N) have both seen very rare reports of cerebral venous sinus thrombosis (CVST) linked to their vaccines. On Wednesday, the United States paused vaccinations using J&J’s shot while a link with clots was investigated, with Denmark ditching AstraZeneca’s shot over the issue. British and European regulators have stressed that the benefits of vaccination outweigh the risks. A study of 500,000 COVID-19 patients found CVST had occurred at a rate of 39 people out of a million following infection, researchers said. That compares with European Medicines Agency (EMA) figures showing that 5 in a million people reported CVST after getting AstraZeneca's shot.

Exercise may strongly protect against poor COVID-19 outcomes
Regular physical activity may substantially reduce the risk of COVID-19–related hospitalization, intensive care unit (ICU) admission, and death, suggests an observational study of nearly 50,000 people published yesterday in the British Journal of Sports Medicine. Kaiser Permanente Southern California researchers led the retrospective study, which involved linking the self-reported physical activity levels of 48,440 adult patients who had at least three exercise vital sign measurements in the 2 years preceding the pandemic to their risk of severe coronavirus outcomes. Used at every outpatient visit at Kaiser Permanente since 2009, exercise vital sign measurements include average number of days a week of moderate to strenuous exercise and duration of that exercise. The patients, who were diagnosed as having COVID-19 from Jan 1 to Oct 21, 2020, reported their physical activity as consistently inactive (0 to 10 minutes a week), some activity (11 to 149 minutes), or consistently meeting guidelines (more than 150 minutes).

Astrazeneca vaccine risk prompts Australian government to recommend Pfizer COVID-19 vaccine for under 50
The Australian government is recommending that Australians under 50 take the Pfizer Inc. COVID-19 vaccine due to the risk of rare blood clots associated with Astrazeneca plc’s COVID-19 vaccine (ChAdOx1-S). The move jeopardizes Australia’s vaccine rollout as it had planned for the majority of Australians to receive the Astrazeneca vaccine, which is being locally manufactured by CSL Ltd.
During a press conference announcing the local manufacture of the vaccine in March, officials were gloating about what a fabulous job the country had done in fighting the COVID-19 pandemic. Now it looks as if it is falling behind on vaccinating its citizens, and Prime Minister Scott Morrison said that essentially “all bets are off” on whether Australians will be vaccinated by the end of the year. Previously, he had said that all Australians would be vaccinated by October.

UK trial on switching COVID-19 vaccines adds Moderna and Novavax shots
A UK study into using different COVID-19 vaccines in two-dose inoculations is being expanded to include shots made by Moderna and Novavax, researchers said on Wednesday. The trial, known as the Com-Cov study, was first launched in February to look at whether giving a first dose of one type of COVID-19 shot, and a second dose of another, elicits an immune response that is as good as using two doses of the same vaccine. The idea, said Matthew Snape, the Oxford University professor leading the trial, “is to explore whether the multiple COVID-19 vaccines that are available can be used more flexibly”.

Vaccine made for South African Covid variant promising, says Moderna
An experimental vaccine targeted at the South African strain of Covid-19 has produced antibodies in laboratory mice, its maker said last night, offering an early sign that it could protect humans against the variant. Moderna is developing a vaccine to target the B.1.351 variant, which was discovered in South Africa, as well as a multivalent vaccine that combines its original vaccination with the South Africa-specific jab. The company is the first to produce a vaccine designed for the variant detected in South Africa and said its pre-clinical trials in mice for both jabs “improved neutralising titers”, meaning that antibodies detected in the blood increased. The multivalent vaccine would provide the broadest level of immunity, according to Moderna.

An Israeli study says a COVID-19 variant can still infect vaccinated people — here's what Fauci says the research means
A small Israeli study indicates that some of the new coronavirus variants may put people who have been vaccinated at higher risk of breakthrough infections, though U.S. health officials questioned some of the wording used in the preliminary research. These types of cases are called “breakthrough infections,” which occur when someone who has completed their COVID-19 vaccination later gets sick from the virus. The preprint, which was published Friday and has not been peer reviewed, gained attention over the weekend after it said that the B.1.351 variant was more likely to infect people in Israel who had been vaccinated with Pfizer Inc.’s PFE, +0.51% COVID-19 vaccine, compared with other strains of the virus.

Newborns of COVID-vaccinated moms may be protected from infection
Two new Israeli studies find that COVID-19 antibodies pass robustly from mothers to their infants in breast milk for 6 weeks after vaccination and that no infants breastfed by their coronavirus-positive mothers had evidence of infection. The first study, led by researchers from Shamir Medical Center in Zerifin, Israel, and published as a research letter yesterday in JAMA, involved 504 breast milk samples from a convenience sample of 84 healthcare workers who chose to be vaccinated against COVID-19 because of their occupational risk for COVID-19 infection. All participants received two doses of the Pfizer/BioNTech coronavirus vaccine 21 days apart and were recruited through ads and social media from throughout Israel from Dec 23, 2020, to Jan 15, 2021. The women provided breast milk samples before they received the vaccine and then once a week for 6 weeks starting 2 weeks after the first dose, and completed weekly questionnaires.

Gilead Sciences has been exploring its antiviral remdesivir for COVID-19 in the outpatient setting, hoping to replicate the success seen in hospitalized patients. But as new treatments emerge, the company now thinks the drug, in its current form, simply doesn’t have a role to play outside hospitals. Gilead has decided to stop a phase 3 trial of remdesivir as an intravenous infusion in high-risk nonhospitalized patients with COVID-19, the company said Monday. The decision wasn’t about efficacy or safety but the “evolution of the COVID-19 landscape,” it said. In other words, Gilead no longer believes there’s a market for IV remdesivir, or Veklury, that requires administration in a healthcare facility for nonhospitalized patients. As vaccine rollouts ramp up, the overall need for COVID-19 treatments will further decline. The shrinking patient pool has likely also made it hard for Gilead to enroll patients in the new study. Veklury, in its current FDA-approved use for hospitalized patients, brought in sales of $1.94 billion in the fourth quarter of 2020 alone. But for 2021, Gilead’s projecting a total haul between $2 billion and $3 billion, depending on how the pandemic evolves.

Why would a Covid vaccine cause rare blood clots? Researchers have found clues
A week after receiving the AstraZeneca Covid-19 vaccine, a 37-year-old woman in Norway went to the emergency department with fever and persistent headaches. A CAT scan of her head showed a blood clot in blood vessels involved in draining the brain, but her levels of platelets, involved in clotting, were low. She was treated with platelet infusions and a blood thinner, but had a bleed in her brain the next day. She underwent surgery to relieve the pressure on her brain but died two days later.
This is the side effect, known as cerebral venous sinus thrombosis, that has caused a week of worries around the Covid-19 vaccine developed by AstraZeneca. On Tuesday, the U.S. government said that it had seen the same effect six times among the 6.8 million people given a dose of a similar vaccine, from Johnson & Johnson, and that it recommended a pause on use of that vaccine “out of an abundance of caution,” while researchers investigated.

Corticosteroid shortens recovery time in COVID-19 patients treated in the community, early trial results show
Budesonide has been found to shorten recovery time in COVID-19 patients aged over 50 years who are being treated in the community, according to interim findings from the Platform Randomised Trial of Interventions Against COVID-19 in Older People (PRINCIPLE). According to the findings, early treatment with the inhaled corticosteroid shortened recovery time by a median of three days in patients with COVID-19 who were at higher risk of more severe illness, and were being treated at home and in other community settings. Inhaled budesonide was added to the PRINCIPLE trial on 28 November 2020, but recruitment stopped on 31 March 2021 after the trial steering committee decided that enough patients had been enrolled to be able to establish if the drug had a meaningful benefit on time to recovery.

China's Sinovac vaccine is 50.7% effective against COVID-19, just reaching the threshold to be a vaccine worth using, a major trial showed
In a rare admission of the weakness of Chinese coronavirus vaccines, the country’s top disease-control official says their effectiveness is low and the government is considering mixing them to get a boost. Chinese vaccines “don’t have very high protection rates,” said the director of the China Centers for Disease Control, Gao Fu, at a conference Saturday in the southwestern city of Chengdu.

Common asthma medicine can speed up Covid-19 recovery by three days – study
A cheap and widely available asthma medicine can speed up the recovery of people with coronavirus who have not been admitted to hospital, new research suggests. Budesonide – an inhaler drug sold under the brand name Pulmicort – is used around the world to treat asthma and COPD, but an Oxford University trial found it can also be used at home to reduce Covid-19 recovery time by an average of three days in those with a heightened risk from the disease. The corticosteroid is safe and is effective during the early stages of coronavirus infection, according to the study.

Previous COVID-19 may cut risk of reinfection 84%
People who had COVID-19 had an 84% lower risk of becoming reinfected and a 93% lower risk of symptomatic infection during 7 months of follow-up, according to findings from a large, multicenter study published late last week in The Lancet. The prospective cohort SARS-CoV-2 Immunity and Reinfection Evaluation (SIREN) study, by Public Health England Colindale researchers, involved 25,661 workers at public hospitals throughout England who were tested for SARS-CoV-2 every 2 to 4 weeks and antibodies at enrollment and every 4 weeks. Volunteers also completed questionnaires on symptoms and exposures every 2 weeks. Of the 25,661 participants, 32.3% were assigned to the baseline positive (possibly or probably previously infected) group, and 67.7% were assigned to the negative group. Of the 8,278 positive participants, 91.2% had SARS-CoV-2 antibodies at study enrollment, while 7.0% were negative for antibodies but had a previously positive antibody and/or coronavirus test, and 1.8% had tested positive for COVID-19 but didn't have linked antibody data

Regeneron says antibody cocktail prevented Covid when given as simple injection, not an IV
Regeneron Pharmaceuticals said Monday that a single administration of its monoclonal antibody cocktail reduced the risk that volunteers exposed to Covid-19 would develop the disease by 81%. The study enrolled 1,500 healthy volunteers, each of whom shared a home with someone who tested positive for SARS-CoV-2, and randomized them to receive a single dose of its antibody treatment, given subcutaneously as four shots, or placebo. After 29 days, 11 patients in the treatment group developed Covid-19 compared to 59 on placebo. And for the subjects who got Covid-19 despite treatment, their symptoms resolved after one week, compared to three weeks for those on placebo. In 204 patients who had already tested positive for the SARS-CoV-2 virus at the study’s outset, the injection reduced their chances of progressing to symptomatic Covid-19 by 31%.

Women report more side effects from the COVID-19 vaccine than men. Health experts explain why.
Reports of COVID-19 vaccine side effects support what many have anecdotally observed: women shoulder the bigger burden. Among nearly 7,000 reports processed through the Centers for Disease Control and Prevention's Vaccine Adverse Event Reporting System (VAERS) from Dec. 14 to Jan. 13, more than 79% of them came from women. The most frequently reported side effects were headache, fatigue and dizziness. Women also are more likely than men to experience some of the vaccine’s more unusual side effects, such as an itchy red rash that appears at the injection site commonly known as COVID arm or Moderna arm, as about 95% of the reactions occur with the Moderna vaccine. Overall, women account for 77% of the Moderna vaccine’s reported side effects.

Blood clots linked to AstraZeneca vaccine stem from rare antibody reaction
Two reports published Friday in a leading medical journal help to explain how AstraZeneca’s COVID vaccine can, in rare cases, cause serious and sometimes fatal blood clots. Scientific teams from Germany and Norway found that people who developed the clots after vaccination had produced antibodies that activated their platelets, a blood component involved in clotting. The new reports add extensive details to what the researchers have already stated publicly about the blood disorder. Why the rare reaction occurred is not known. Younger people appear more susceptible than older ones, but researchers say no preexisting health conditions are known to predispose people to the problem, so there is no way to tell if an individual is at high risk. Reports of the clots have already led a number of countries to limit AstraZeneca’s vaccine to older people, or to stop using it entirely. The cases have dealt a crushing blow to global efforts to halt the pandemic, because the AstraZeneca shot — easy to store and relatively cheap — has been a mainstay of vaccination programs in more than 100 countries.

Studies suggest link between blood clots, AstraZeneca COVID vaccine
Two studies today in the New England Journal of Medicine describe 11 patients in Austria and Germany and 5 in Norway who developed an unusual blood clotting disorder after receiving their first dose of the AstraZeneca/Oxford COVID-19 vaccine. The first study, led by researchers at the Institute for Immunology and Transfusion Medicine in Greifswald, Germany, involved 11 patients who had abnormal blood clots or thrombocytopenia (low platelet counts) 5 to 16 days after receiving the AstraZeneca vaccine. One patient had a fatal intracranial hemorrhage (bleeding in the brain), while nine had cerebral venous thrombosis (blood clots in the brain), three had splanchnic vein thrombosis (blood clots in abdominal veins), three had a pulmonary embolism (blockage in a lung artery caused by blood clots), and four had other types of blood clots. Six patients, in addition to the patient with fatal intracranial hemorrhage, died.

Reports detail high COVID-19 burden in Native Americans
During the pandemic, Native Americans have had 2.2 times greater COVID-19 case incidence and almost quadruple the death rate of White people in Montana, according to a study today in Morbidity & Mortality Weekly Report (MMWR).
A separate MMWR report looked at COVID-19 cases and response on a 10,000-member tribal reservation in Montana, while a third detailed control efforts taken on a North Dakota reservation.
All three research teams suggest that Native American populations are disproportionately vulnerable during the pandemic and benefit from COVID-19 mitigations.

COVID-19: Study finds link with brain, mental health conditions
A study suggests that in the United States in 2020, around a third of COVID-19 survivors were diagnosed with a neurological or mental health condition within 6 months of their COVID-19 diagnoses. Anxiety and mood disorders were the most common diagnoses. Neurological conditions, such as stroke and dementia, occurred less often but were more common among people with severe COVID-19.
The overall effect of these disorders, many of which are chronic, may be substantial for health and social care systems due to the scale of the pandemic.

Brazil finds new virus variant combining 18 mutations
Scientists in Brazil have discovered a new variant of coronavirus that combines 18 mutations, rubbing salt in the wound of the South American epicenter. The new strain from Belo Horizonte city "has characteristics in common with the variants that were already circulating in Brazil but it also has new characteristics," Virologist Renato Santana from the Federal University of Minas Gerais told local daily G1 on Wednesday. "It is as if these variants were evolving," Santana said, adding the new variant includes the same genes modified by Brazil's Manaus, known as P1, British and South African variant. Noting that it is early to assess whether the new strain more transmissible or deadly, he said that it has mutations in common with variants that are already associated with a higher risk of death. The new super variant made headlines at a critical time when Brazil registered record-high single-day COVID-19 deaths with more than 4,000.

How dangerous is India’s ‘double mutant’ COVID-19 variant?
In late March, India’s National Centre for Disease Control (NCDC), a division of the Ministry of Health and Family Welfare, announced that a new variant – dubbed a “double mutant” – had been identified in samples of saliva taken from people in Maharashtra, Delhi and Punjab. This comes on the back of a month that has seen a surge in cases of COVID-19 across India, with many states re-imposing curfews, restrictions and lockdown measures. The Ministry of Health and Family Welfare says this new “double mutant” variant has not been found in sufficient numbers to account for the increase in COVID-19 cases across the country. That, rather, is thought to be due to large public gatherings such as weddings, the opening of cinema halls and gyms, as well as large political rallies in West Bengal where elections are due to be held soon. Nevertheless, it is a “variant of concern” (VOC) and is being closely monitored. The genome sequencing carried out by a consortium of 10 labs in India, called the Indian SARS-CoV-2 Consortium on Genomics (INSACOG), has identified two important mutations in the new variant, giving it the unfortunate title of “double mutant”.

Britain reassures on AstraZeneca after advising under-30s take other vaccines
British officials and ministers sought to shore up confidence in AstraZeneca’s COVID-19 vaccine on Thursday, saying advice that most people under 30 should be offered alternative shots was not unusual and would not impact the pace of rollout. A pharmacist whose brother died from a brain blood clot linked to the AstraZeneca shot was among those calling for people to keep getting it, saying the doses would save lives. Officials said the suggestion that under-30s should be offered an alternative did not reflect any serious safety concerns, just a “vanishingly” rare possible side effect.

In the race to stay ahead of COVID-19 variants, the US lags globally
The vaccines going in our arms could become less effective as the coronavirus mutates, a problem that demands scientists meticulously track variants to protect us. The United States lags many other countries in employing the essential tool for keeping abreast of variants – gene sequencing – increasing the risk that a variant could spread undetected. This year, the United States ranks 33rd in the world for its rate of sequencing, falling between Burkina Faso and Zimbabwe, according to COVID CoV Genomic, led by researchers at Harvard and MIT. The top three nations – Iceland, Australia and New Zealand – sequenced at a rate 55 to 95 times greater.

EU agency: Rare clots possibly linked to AstraZeneca shot
British authorities recommended Wednesday that the AstraZeneca COVID-19 vaccine not be given to adults under 30 where possible because of strengthening evidence that the shot may be linked to rare blood clots. The recommendation came as regulators in the United Kingdom and the European Union emphasized that the benefits of receiving the vaccine continue to outweigh the risks for most people — even though the European Medicines Agency said it had found a “possible link” between the shot and the rare clots. British authorities recommended that people under 30 be offered alternatives to AstraZeneca. But the EMA advised no such age restrictions, leaving it up to its member-countries to decide whether to limit its use.

AstraZeneca COVID-19 shot tagged with new warning in EU, highlighting rare blood clot risk
Europe’s drug regulator has been probing cases of rare blood clots in AstraZeneca COVID-19 vaccine recipients since mid-March—and now it has confirmed a possible link. The agency stressed that the benefits of the shot still outweigh the risks. Unusual blood clots with low blood platelets should be listed as a “very rare” side effect of the vaccine, the European Medicines Agency (EMA) said Wednesday. Incidents have mostly been reported within two weeks of vaccination in women below the age of 60. With cases piling up over the past month, several countries have stopped using the shot altogether. The EMA's safety arm, the Pharmacovigilance Risk Assessment Committee (PRAC), specifically noted clots in the brain, abdomen and arteries associated with thrombocytopenia, or low levels of blood platelets.

Covid-19 reinfections are rare — but without better data, we don’t how rare
Reinfections from Covid-19 continue to seem rare, and are not responsible for the current, stubbornly high case counts in the United States, according to scientists and the latest findings. At least, that’s what researchers are left to conclude. Experts say the country and individual states don’t have strong systems to determine how frequently people are getting reinfected — another consequence of the nation’s limited surveillance network. They’re calling for better data collection and analysis around second cases of Covid-19. The main factors driving coronavirus transmission in the United States are a mix of the old — easing restrictions, people coming into close contact with others — and the new, like the more transmissible variants, experts say. And Caitlin Rivers, an infectious disease epidemiologist at the Johns Hopkins Center for Health Security, said she thought that reinfections are still uncommon.

Oxford pauses AstraZeneca vaccine study on children
Oxford university has called a pause to a small clinical trial in children of the Covid-19 vaccine developed with AstraZeneca, ahead of new risk assessments this week by regulators investigating possible links between the jab and rare but potentially fatal blood disorders in adults. The suspension of the trial, which was running tests in 300 volunteers aged 6 to 17, is the latest setback for a product seen as a mainstay of vaccination programmes in the UK and around the world.
The university said it had decided to suspend the trial ahead of the release of “additional information” from the Medicines and Healthcare products Regulatory Agency, the UK regulator, following its review of cases of thrombosis (blood clotting) and thrombocytopenia (low platelet count) in some adults. It said there were “no safety concerns in the paediatric study”

With the third-highest rate of inoculations in Europe, Serbia is viewed as something of a Balkan success. But the country has been struggling to find people to vaccinate. Under Serbian President Aleksandar Vucic, Serbia has procured enough vaccines to inoculate its population of seven million, but supply is outpacing demand amid vaccine hesitancy. Vucic announced in early March that Serbia had nearly 15 million vaccines, but by March 25, Serbian authorities told reporters that just 1.3 million people had been vaccinated. Last weekend, thousands of foreigners from the region crossed borders to get free jabs in Serbia. In three days more than 22,000 foreigners were inoculated. It was a pragmatic move.

It has also emerged that young people are up to 35 times more likely to die of Covid than to develop the type of brain blood clot that European officials fear could be caused by AstraZeneca's jab, figures suggest. German medics have seen one case of CVST - a type of rare brain blood clot that can cause strokes - in every 90,000 people to receive the vaccine, and say that is higher than expected. It is equal to a rate of 0.0012 per cent.

Doctors put ‘on alert’ for blood-clotting syndrome after seven UK deaths following AstraZeneca vaccine
Doctors have been issued with new advice to help them spot a rare blood-clotting disorder that may be linked to the Oxford-AstraZeneca coronavirus vaccine, as the UK’s medicines regulator confirms seven deaths. The British Society for Haematology decided to act after some experts became concerned at the number of cases of blood clotting linked to a rare syndrome known as thrombocytopenia.
It said doctors needed to be “on alert” for the condition and what to look for, how to treat it and how to report cases so the data can be properly collated. Thrombocytopenia involves patients having abnormally low numbers of platelet cells in their blood. Platelets help blood to clot after an injury.

Coronavirus live news: Pfizer vaccine has 100% efficacy against South African variant in small trial
Two shots of the Pfizer vaccine produce high levels of protective antibodies in people 80 and over, according to the largest independent study yet into older people’s immune responses to the jab. Blood tests on 100 people aged 80- to 96-years-old found that 98% produced strong antibody responses after two doses of the vaccine given three weeks apart. After the second shot, antibody levels more than tripled. The findings, released in a preprint that has yet to be peer-reviewed, will boost confidence that the Pfizer vaccine can be highly effective against Covid even in older people who tend to generate far weaker immune responses to both vaccines and natural infections. But it is unclear what the findings mean for the UK where second shots of vaccine are given up to three months after the first.

Finnish coronavirus vaccine study shows sharp drop in hospitalisations
Coronavirus vaccinations in Finland reduced the number of severe Covid-19 cases requiring hospitalisation by an average of 74 percent in people aged over 70 and by an average of 84 percent in at-risk groups, according to the Institute for Health and Welfare (THL), which published preliminary results of a study on the matter on Wednesday. The study compared the likelihood of hospitalisation for coronavirus in vaccinated and non-vaccinated patients. The results largely reflect the efficacy of a single dose of the vaccine, as only 10 percent of the study's participants had received a second dose during the study period. "Estimates of vaccine efficacy are in line with results internationally. Four weeks after receiving the first dose of the vaccine, efficacy was 78 percent in Israel, 81 percent in Scotland and 71-80 percent in England," said Tuija Leino, head of the immunisation programme at THL.

School-acquired coronavirus infections made up 3.15% of all cases in the first scenario, 4.19% in the second and 2.37% in the third. Researchers say this shows that other mitigation measures should be taken to stop the spread of COVID-19 before schools are closed

No rare blood clots in first 440,000 people vaccinated for coronavirus in Wales
No cases of a blood clotting disorder have been found in the first 440,000 people vaccinated against Covid-19 in Wales. Scientists in Swansea University looked at anonymised patient data between January 1, 2019 and January 31, 2021 to determine whether there had been a rise in cases of venous sinus thromboembolism. The extremely rare condition was found in a small number of patients in Norway and Germany and was one of the reasons why several European countries decided to temporarily halt the use of the Oxford AstraZeneca vaccine. However the Medicines and Healthcare products Regulatory Agency (MHRA) said there has been no confirmation the reports of blood clots were caused by the vaccine.

Covid: Half of UK has antibodies from vaccination or infection
Roughly half of people in the UK now have antibodies against Covid, either through infection or vaccination, tests conducted by the Office for National Statistics (ONS) show. Most of this will be through vaccination - with 30 million people having received at least one dose. Antibodies are proteins in the blood which recognise specific infections and fight them off. Among the oldest who are most at risk, levels are even higher. But there has been a small decline in detectable antibodies in that group since the peak of infections in January.

Covid jab probably does protect those around you
The Covid-19 vaccine blocks pretty much all cases of serious illness - but the government has been much more cautious about saying whether it stops people carrying the virus and infecting others. Until evidence had built up from lots of people being vaccinated, scientists could not say for sure if the jab would stop transmission - and there was concern those vaccinated might stop taking precautions, potentially leading to a rise in infections. But with some now refusing the vaccine in the belief it will not stop them passing on the virus, is this caution becoming counterproductive? A number of people have contacted the BBC, saying they believe the jab could stop them becoming severely ill only.

Many hospitalized Covid-19 patients are given antibiotics. That’s a problem
As the Covid-19 pandemic continues into its second year, public health experts are increasingly concerned that the response to this global crisis may be accelerating another one: the development and persistence of the antibiotic-resistant bacteria known as superbugs. Why? All antibiotic use hastens the emergence of resistance. And although antibiotics aren’t used to treat Covid-19, which is a viral illness, they’re often prescribed to Covid-19 patients who are at risk for bacterial infection.
New research from our organization, the Pew Charitable Trusts, sheds additional light on the extent to which antibiotics are being prescribed unnecessarily in the midst of the pandemic. In a study of nearly 6,000 hospital admissions between February and July 2020 among patients with Covid-19, at least one course of antibiotics was given to more than half (52%) during their hospital stays.

T cells induced by COVID-19 infection respond to new virus variants: U.S. study
A critical component of the immune system known as T cells that respond to fight infection from the original version of the novel coronavirus appear to also protect against three of the most concerning new virus variants, according to a U.S. laboratory study released on Tuesday. Several recent studies have shown that certain variants of the novel coronavirus can undermine immune protection from antibodies and vaccines. But antibodies - which block the coronavirus from attaching to human cells - may not tell the whole story, according to the study by researchers at the National Institute of Allergy and Infectious Diseases (NIAID). T cells appear to play an important additionally protective role. “Our data, as well as the results from other groups, shows that the T cell response to COVID-19 in individuals infected with the initial viral variants appears to fully recognize the major new variants identified in the UK, South Africa and Brazil,” said Andrew Redd of the NIAID and Johns Hopkins University School of Medicine who led the study.

Risk of SARS-CoV-2 transmission from newly-infected individuals with documented previous infection or vaccination
Direct evidence of the impact of vaccination on the risk of transmission is only available from one study, a large register-based household transmission study from Scotland. This study suggests that vaccination of a household member reduces the risk of infection in susceptible household members by at least 30%. There is evidence that vaccination significantly reduces viral load and symptomatic/asymptomatic infections in vaccinated individuals, which could translate into reduced transmission, although the vaccine efficacy varies by vaccine product and target group. In light of this fact, the total number of infections is expected to decrease significantly as vaccination coverage increases, provided that there is a match between the vaccine strains and the circulating virus strains. This will lead to decreased transmission overall. Follow-up periods for vaccinated persons are not yet sufficiently long enough to draw conclusions on the duration of protection against infection long-term. Antibody titres in vaccinated individuals peak at 3−4 weeks following vaccination. Many of the vaccine efficacy studies were carried out before the emergence of SARS-CoV-2 VOCs. In studies that address the variants, there is limited preliminary evidence of reduced vaccine efficacy, in particular for B.1.351 and possibly also for P.1.

COVID-19 vaccines found to be highly effective in real-world CDC study
The U.S. government’s first look at the real-world use of COVID-19 vaccines found their effectiveness was nearly as robust as it was in controlled studies. The two vaccines available since December — Pfizer and Moderna — were highly effective at 90% after two doses, the Centers for Disease Control and Prevention reported Monday. In testing, the vaccines were about 95% effective in preventing COVID-19.
“This is very reassuring news,” said the CDC’s Mark Thompson, the study’s lead author. “We have a vaccine that’s working very well.”

WHO draft report says animals likely source of COVID-19
A joint World Health Organization-China study on the origins of COVID-19 says that transmission of the virus from bats to humans through another animal is the most likely scenario and that a lab leak is “extremely unlikely,” according to a draft copy obtained by The Associated Press. The findings offer little new insight into how the virus first emerged and leave many questions unanswered. But the report does provide more detail on the reasoning behind the researchers’ conclusions. The team proposed further research in every area except the lab leak hypothesis — a speculative theory that was promoted by former U.S. President Donald Trump among others. It also said the role played by a seafood market where human cases were first identified was uncertain.

COVID-19 antibodies appear to ward off B117 better than B1351
COVID-19 survivors and those vaccinated against coronavirus appear able to fight off infection with the B117 SARS-CoV-2 variant but may not have the same level of protection against the B1351 variant, according to two new studies. In the first study, published late last week in Nature Medicine, researchers at Institut Pasteur in Paris isolated infectious B117, the variant first identified in the United Kingdom, and B1351, first discovered in South Africa, from the nasal swabs of symptomatic COVID-19 patients. Like some other emerging variants, B117 and B1351 are more infectious than previously dominant varieties, leading to fears that they could evade natural and vaccine-induced immunity.

Covid: How this Indian firm is vaccinating the world
As pharmaceutical giants ramp up production in the race to vaccinate the world, one firm has shot into the lead. The Serum Institute of India (SII) isn't a household name, but it's the world's largest vaccine maker. The firm churns out 1.5 billion doses every year from the company's vast manufacturing plant in Pune, Western India. It is currently making Covid vaccines under license for pharmaceutical firms such as AstraZeneca. "We took a huge calculated risk", by betting on several vaccines in 2020 before regulators had even approved of them, SII's chief executive Adar Poonawalla told the BBC. "It wasn't a blind risk, because we knew the Oxford scientists from our earlier collaboration with the malaria vaccine."

Joint jab for Covid-19 and flu could be ready next year, says top vaccine developer
Scientists at Imperial College London have demonstrated ‘proof of principle’ and hope to begin developing the joint vaccine later this year. A joint jab for Covid-19 and flu could be ready for use by the end of next year, according to one of Britain’s leading vaccine developers. Professor Robin Shattock, of Imperial College London, said the combination jab “is in our sights” after successfully combining three existing vaccines into one shot using the RNA technology he is developing. Tests of the three-in-one vaccine shot he created for Ebola, Marburg and Lassa fever produced the “same type of immune response” in mice as if they had been administered separately, he said.

Researchers in the U.S. and abroad are beginning to test younger and younger kids to make sure COVID-19 vaccines are safe and work for each age. The first shots are going to adults who are most at risk from the coronavirus, but ending the pandemic will require vaccinating children too.

Can one vaccine ward off all coronavirus? Researchers are about to find out
Variants of the virus that causes COVID-19 are emerging and becoming dominant around the world. So some vaccines are being updated to allow our immune system to learn how to deal with them. But this process of identifying and characterising variants that can escape our immune system, then tweaking a vaccine to deal with them, can take time. So researchers are designing a universal coronavirus vaccine. This could mean one vaccine to protect against different variants of SARS-CoV-2, the coronavirus that causes COVID-19. Alternatively, a universal vaccine would target many different coronaviruses, perhaps one waiting in the wings to cause the next pandemic. Here's where the science is up to and the challenges ahead.

Britain gives go-ahead to 20-second COVID-19 test, distributor says
A 20-second COVID-19 test will launch in Britain after regulators accepted its registration, the product’s distributor said on Friday, heralding a testing system it said could be used in airports, sports venues and businesses. Rapid tests are seen as a key plank of Prime Minister Boris Johnson’s roadmap out of lockdown, but concerns have been expressed about the accuracy of existing lateral flow devices.
The Virolens test, which is made by British start-up iAbra and TT Electronics, has been piloted at Heathrow Airport, and uses swabs of saliva. Histate, which is distributing the test, said it would launch with immediate effect after the Medicines and Healthcare products Regulatory Agency (MHRA) accepted the registration of the product, and the company said it was hoping for a wider rollout in coming months.

Covid: Past infection increases vaccine response six-fold
Health workers with previous Covid-19 infections had six times the immune response to one dose of the Pfizer jab than those who hadn't had the virus. The researchers said this emphasised the importance of people having their second dose to provide the same "booster" effect. Those who have had Covid should still have a second jab, though, to ensure "longer-lasting" protection. Giving the previously-infected one dose would not be efficient, experts say. Having two jabs gives the best chance of activating all parts of the immune system and potentially protecting against new variants. The study, funded by the Department of Health and Social Care, was an extension of Public Health England's Siren study of healthcare workers.

U.S. COVID response could have avoided hundreds of thousands of deaths - research
The United States squandered both money and lives in its response to the coronavirus pandemic, and it could have avoided nearly 400,000 deaths with a more effective health strategy and trimmed federal spending by hundreds of billions of dollars while still supporting those who needed it. That is the conclusion of a group of research papers released at a Brookings Institution conference this week, offering an early and broad start to what will likely be an intense effort in coming years to assess the response to the worst pandemic in a century. U.S. COVID-19 fatalities could have stayed under 300,000, versus a death toll of 540,000 and rising, if by last May the country had adopted widespread mask, social distancing, and testing protocols while awaiting a vaccine, estimated Andrew Atkeson, economics professor at University of California, Los Angeles.

BNT162b2 mRNA Covid-19 Vaccine Effectiveness among Health Care Workers
Since the introduction of Covid-19 vaccines, prioritizing vaccination of health care workers has been advocated, and data on vaccine effectiveness among health care workers in real-world settings is beginning to emerge. In our study that was conducted in an active hospital setting in a community with a high incidence of Covid-19, vaccination of health care workers with the BNT162b2 vaccine resulted in a major reduction of new cases of Covid-19 among those who received two doses of the vaccine, even when a surge of the B.1.1.7 variant was noted in up to 80% of cases.5 These findings suggest that widespread and effective vaccination among health care workers provides a safe environment, even in the presence of a high rate of SARS-CoV-2 infection in the community.

School return has been major factor in plateau of Covid-19 cases, data suggests
The reopening of schools has been a major factor in the recent plateau in Covid-19 cases, new data suggests. Daily case numbers fell rapidly throughout January and February but have remained stagnant at about 500-600 a day over the past month. The National Public Health Emergency Team (Nphet) and the government have repeatedly said that the staged reopening of schools, which began on February 23, is not responsible for the plateau, instead blaming an increase in people meeting up and socialising. However, data from the Health Protection Surveillance Centre (HSPC) shows that Covid-19 cases in children have increased by almost 20 per cent in the past month while cases among the adult population have decreased by more than 10 per cent.

Why Insomnia And Burnout May Increase Your Covid Risk
If there’s one thing that’s become clear as the pandemic has stretched on, it’s that there’s a lot to be explored in the relationship between Covid-19 and poor sleep. We already knew the two were linked. An analysis of sleep studies found sleep problems affected approximately 40% of people in the pandemic – and those who caught Covid-19 appeared to have a higher prevalence of sleep problems. Now, a study suggests if you had sleep problems prior to getting coronavirus, or suffered daily burnout, you have a heightened risk of not only becoming infected with the virus, but also having more severe disease. Every one-hour increase in the amount of time spent asleep at night was associated with 12% lower odds of becoming infected with Covid-19, according to the study published in the online journal BMJ Nutrition Prevention & Health.

COVID-19 'long haulers' need dedicated clinics, experts say
The United States should create multispecialty COVID-19 clinics dedicated to treating patients still experiencing serious multiorgan effects of infection well after recovery from acute illness, say the authors of a comprehensive review of literature on so-called coronavirus "long-haulers" published yesterday in Nature Medicine. The exact number of US long-haul COVID-19 cases is unknown, but the researchers said that many patients struggle in silence or become frustrated when their doctors don't consider that their symptoms could be related to their previous infection. The review, led by researchers at New York-Presbyterian/Columbia University Irving Medical Center, found that the cell damage, inflammatory immune response, abnormal blood clotting, and other complications of acute COVID-19 infection can leave in their wake long-term symptoms such as chest pain, shortness of breath, "brain fog," fatigue, joint pain, and posttraumatic stress disorder, all of which can compromise quality of life. The researchers detailed literature from the United States, Europe, and China on high percentages of long-haulers, or those with chronic or post–COVID-19 syndrome, who often have debilitating symptoms for more than 3 months. COVID-19 has been associated with diabetes, strokes, heart rhythm abnormalities, blood clots in the lungs, and other complications.

Regeneron, Roche COVID-19 antibody cocktail slashes hospitalizations and tackles variants in phase 3
Even as COVID-19 vaccines roll out across the globe, promising to eventually spark herd immunity to the virus, Regeneron’s executives have been preaching the value of having a powerful antibody cocktail on hand to treat those who do get sick—and to protect those who aren’t vaccinated. Now Regeneron and its partner Roche have fresh phase 3 data to back up the theory. And if regulators agree with them, they could have a blockbuster on their hands, analysts have estimated. The treatment, a combination of casirivimab with imdevimab, lowered the risk of hospitalization or death in high-risk, non-hospitalized patients by 70% compared with placebo, the companies said. The drug combo also retained its potency against five major variants, including those originating in South Africa, the U.K. and New York City. It was effective at three different doses, as well.

What we know and don’t know about long Covid
Whether you call it long Covid or post-acute Covid-19 or just identify yourself as a long-hauler, the constellation of prolonged symptoms after Covid-19 infection has become all too familiar. About one-third of people who were sick enough to need hospitalization — including supplemental oxygen or mechanical ventilation to breathe — still struggle with problems affecting their bodies and their minds four weeks or more after the first onset of symptoms. About 1 in 10 people who had Covid but were never admitted to a hospital report they experience bewildering brain fog, shortness of breath, muscle weakness, or crushing fatigue in the months after the first signs of their initial illness. Some see no end in sight; others seem to recover. To help understand how to recognize and treat this mysterious condition, researchers from Harvard and Columbia culled the scientific literature to guide treatment for nine organ systems where the SARS-CoV-2 virus does its damage.

A rapid COVID-19 vaccine rollout backfired in some US states
A surprising new analysis found that states such as South Carolina, Florida and Missouri that raced ahead of others to offer the vaccine to ever-larger groups of people have vaccinated smaller shares of their population than those that moved more slowly and methodically, such as Hawaii and Connecticut. The explanation, as experts see it, is that the rapid expansion of eligibility caused a surge in demand too big for some states to handle and led to serious disarray. Vaccine supplies proved insufficient or unpredictable, websites crashed and phone lines became jammed, spreading confusion, frustration and resignation among many people. “The infrastructure just wasn’t ready. It kind of backfired,” said Dr. Rebecca Wurtz, an infectious disease physician and health data specialist at the University of Minnesota’s School of Public Health. She added: “In the rush to satisfy everyone, governors satisfied few and frustrated many.”

GPs ‘at least 30% less likely’ to pass Covid-19 on to others after one vaccine dose
Chances of healthcare workers passing Covid onto others reduced by at least 30% after one vaccine dose, according to the first UK study into the transmission of coronavirus following vaccination. Quoting the research in yesterday’s coronavirus briefing, health secretary Matt Hancock said ‘it shows that the vaccines are saving lives’. The study, which included 300,000 people, saw researchers assess the health records of people who lived with vaccinated and unvaccinated healthcare workers between 8 December and 3 March to find how many tested positive for Covid-19 or were hospitalised. The yet-to-be-peer-reviewed study, carried out by Public Health Scotland and the University of Glasgow, suggested that after one vaccine dose healthcare workers are at least 30% less likely to pass Covid onto others, with this rising to 54% less likely after a second dose. The researchers said this is a low estimate of the ‘true’ impact of the vaccines, given that household members of healthcare workers could also be infected through people they do not live with.

Covid-19 reinfections are rare, unless you are over 65
Coronavirus reinfections are rare, but it's more common for people 65 and older to get infected more than once, according to a study published Wednesday in the Lancet medical journal. The study, which looked at reinfection rates among 4 million people in Denmark, found that most people who have had Covid-19 seemed to have protection from reinfection for more than six months. In a follow-up after six months, the study found no evidence that protection was waning. But a check of the demographics of who was getting infected again showed it was mostly people 65 and older, Jen Christensen reports.

J&J developing several next-generation COVID-19 vaccines, says CEO
Johnson & Johnson is developing several next generation COVID-19 vaccines against the emerging variants of the coronavirus, Chief Executive Officer Alex Gorsky said on Thursday. The drugmaker, which won the U.S. emergency use authorization of a one-shot vaccine last month, had previously said it was developing a second-generation vaccine that would target the variant first identified in South Africa. J&J is also working on a two-dose version of its vaccine. "We could be in a situation where you could either need a booster to maintain the durability (of protection against the virus) or you might need to have a next derivative of the current vaccine to address these variants as they develop", Gorsky said at a webinar by the Economic Club of New York.

Half of hospital COVID survivors note symptoms 4 months on
Half of French COVID-19 survivors who were hospitalized (51.0%) had at least one COVID-related symptom at least 4 months later, according to a study published yesterday in JAMA. The most commonly noted symptoms were fatigue (31.1%), cognitive conditions (20.7%), and shortness of breath (16.3%). Further clinical tests in a subset of 177 patients showed that 63.2% had abnormalities on lung computed tomography (CT) scan, but the researchers note that severe pulmonary after-effects were not common. "Along with funding for research to better understand and treat long COVID, simultaneous investment in clinical infrastructure will be needed to support patients as they recover from this challenging disease," writes Hallie Prescott, MD, MSc, of the University of Michigan, in an invited editorial.

Trending Clinical Topic: PASC
At a recent White House briefing, Anthony Fauci, MD, introduced a new acronym for what had been called "long COVID." PASC is the new term used to describe long-lingering effects of COVID-19 (see Infographic below) and is this week's top trending clinical topic. At the briefing, Fauci stressed that even patients with moderate cases of COVID-19 can develop PASC. "New symptoms sometimes arise well after the time of infection, or they evolve over time and persist for months," he explained. "They can range from mild or annoying to actually quite incapacitating." Fauci noted that the National Institutes of Health recently launched an initiative to further study the phenomenon.

Scots university's pioneering Covid-19 antibody test is 'more accurate' than those currently available
A new Covid-19 antibody test that’s better than those currently available has been developed by researchers at a Scots university. Serology tests detect if a person has previously had the virus and are important tools in tracing its spread. However, some existing antibody tests are not suited to rapid mass deployment as they can be inaccurate and also detect other coronaviruses including some versions of the common cold. In response to the Chief Scientist Office’s rapid research funding, Aberdeen University, in collaboration with Vertebrate Antibodies and NHS Grampian, has developed a test that has shown high levels of accuracy in smaller trials. The next step is to start a trial on a larger cohort.

CDC IDs new COVID-19 variants of concern, as hot spots reemerge
The Centers for Disease Control and Prevention (CDC) said two coronavirus variants first detected in California, B.1427 and B.1429, are now considered as variants of concern. The CDC said the variants may be 20% more transmissible.
In comparison, the variant B117, first identified in the United Kingdom, is considered 50% more transmissible than the original wild type COVID-19 virus. Neither of the new variants of concern are thought to escape the effectiveness of currently approved vaccines, but therapeutics, including monoclonal antibody treatments, may be slightly less effective. Currently, the CDC's variant tracker shows 4,686 B117 cases in 50 states, 142 B1351 cases in 25 states, and 27 P1 cases in 12 states.

UK nursing homes saw spikes in B117 COVID variant in early winter
The proportion of COVID-19 cases caused by the SARS-CoV-2 B117 variant in UK nursing homes rose from 12.0% on Nov 16 to 60.4% on Dec 13, mirroring the variant’s spread in the community, according to a research letter published yesterday in the New England Journal of Medicine. Researchers from University College London examined a sample of 4,442 positive COVID-19 tests from nursing home residents and staff from Oct 5 to Dec 17 to determine the proportion of cases caused by B117, the variant first discovered in the United Kingdom. UK nursing home staff are tested weekly, and residents are tested monthly. COVID-19 cases and hospitalizations increased rapidly in southeast England in November and December, despite lockdowns. More than half of the cases were attributed to B117, which studies have suggested is more deadly and spreads 40% to 70% more easily than previous strains, and was behind the rise of infections in England in early winter.

mRNA vaccines spur lymph nodes for longer-term protection; COVID-19 test accuracy may vary by time of day
Along with inducing antibodies for immediate defense, mRNA vaccines against COVID-19 also stimulate the lymph nodes to generate immune cells that provide protection over the long term, a new study confirms. The early wave of antibodies are generated by B cells called plasmablasts. In healthy volunteers, blood tests showed that two doses of the Pfizer/BioNTech vaccine induced "a strong plasmablast response," said coauthor Ali Ellebedy of Washington University School of Medicine in St. Louis. The immune cells that will produce antibodies upon exposure to the virus in years to come - called memory B cells - are generated by germinal center B cells found only in lymph nodes near vaccine injection sites, his team explained in a paper currently undergoing peer review for possible publication in a Nature journal.

They describe the new test as “highly accurate, affordable, suitable for mass rollout” – while it also does not require specialised laboratories. Covid-19 antibody – sometimes called serology – tests confirm whether a person has previously had coronavirus. They can be used to manage the pandemic by monitoring how many people have had the virus and how it is spreading. The tests can also be used to monitor the effectiveness of vaccines, population immunity and the impact of new strains of the disease.

Long Covid more common in women and children and lasts for months, warns latest review
Lasting effects of infection from coronavirus are more common in women and children than expected, with at least 10 per cent of people infected suffering persistent symptoms for months, a new review has found. Experts at the National Institute for Health Research (NIHR) examined more than 300 separate scientific studies for the analysis. It found many patients reported struggling to access testing and help from the NHS to treat their symptoms, which varied between patients, suggesting long Covid is a group of four possible syndromes affecting patients differently. The report said: “Long Covid appears to be more frequent in women and in young people (including children) than might have been expected,” adding other sufferers could be experiencing an active disease, impacting on their organs and causing debilitating symptoms that would need ongoing treatment. In some patients, the effects included neurological changes in their brains while others showed signs of blood clotting and inflammation. Other patients reported anxiety, fatigue and damage to their lungs and heart.

B117 deadlier than other COVID-19 strains, more data affirm
The B117 COVID-19 variant, which was first identified in the United Kingdom in October 2020, may pose a 61% higher risk of 28-day mortality, according to a study published today in Nature. The finding is in line with last week's BMJ study that reported B117 had a 64% higher 28-day risk of death among people older than 30, although both studies note absolute 28-day mortality risk remains low for most populations. "Crucially, our study is limited to individuals tested in the community," the researchers write. "However, this restricted focus allows us to capture the combined effect of an altered risk of hospitalisation given a positive test and an altered risk of death given hospitalisation, while only the latter would be measurable in a study of hospitalised patients only."

Single Covid vaccine dose less effective for cancer patients, study finds
Cancer patients given a single coronavirus vaccine develop significantly inferior protection against the illness than those who receive a booster shot, according to a UK study that called for a reassessment of the gap between jabs for vulnerable individuals. Three weeks after receiving a first dose of the BioNTech/Pfizer vaccine, sufficient antibody levels to combat the virus were detected in 39 per cent of patients with organ cancer and 13 per cent of those with blood cancer, found researchers at King’s College London and the Francis Crick Institute. This compared with 97 per cent of those who were cancer free. When a second shot was given, however, the effectiveness of the vaccine jumped to about 95 per cent after two weeks in organ cancers patients, the study found. There was insufficient data to reach a conclusion on blood cancer patients. The researchers did not test the effectiveness of any other coronavirus vaccine.

The upcoming guidance, first reported by Politico, is expected to include that fully vaccinated individuals should be able to gather in small groups with other people who have also been vaccinated. The CDC currently does not recommend in-person gatherings with the general public, saying "gathering virtually or with the people you live with is the safest choice."

Exclusive: Oxford study indicates AstraZeneca effective against Brazil variant, source says
Preliminary data from a study conducted at the University of Oxford indicates that the COVID-19 vaccine developed by AstraZeneca PLC is effective against the P1, or Brazilian, variant, a source with knowledge of the study told Reuters on Friday.
The data indicates that the vaccine will not need to be modified in order to protect against the variant, which is believed to have originated in the Amazonian city of Manaus, said the source, who requested anonymity as the results have not yet been made public. The source did not provide the exact efficacy of the vaccine against the variant. They said the full results of the study should be released soon, possibly in March.

FDA authorizes new test, built with machine learning, to detect past Covid-19 infections
The Food and Drug Administration on Friday issued an emergency authorization for a new test to detect Covid-19 infections — one that stands apart from the hundreds already authorized. Unlike tests that detect bits of SARS-CoV-2 or antibodies to it, the new test, called T-Detect COVID, looks for signals of past infections in the body’s adaptive immune system — in particular, the T cells that help the body remember what its viral enemies look like. Developed by Seattle-based Adaptive Biotechnologies, it is the first test of its kind. Adaptive’s approach involves mapping antigens to their matching receptors on the surface of T cells. They and other researchers had already shown that the cast of T cells floating around in an individual’s blood reflects the diseases they’ve encountered, in many cases years later. The next step is trying to unlock that information to help diagnose those past infections.

Coronavirus: will immunity rapidly fade or last a lifetime?
The COVID vaccines are working. Data from Israel and Scotland shows that they are protecting people and may also be decreasing the spread of the SARS-CoV-2 virus. If it all holds up, people will be protected from severe disease, the amount of virus will progressively decrease, and we can truly plan for a way out of the pandemic. Evidence is also growing that once you’ve been infected, there is a pretty good chance that you will be protected from further infections, or at the very least, have less severe disease. This makes sense, as it’s why your immune system evolved in the first place. However, an important question in immunology, when it comes to infectious diseases and vaccines, is: how long protection might last? There are several variables here, from the type of pathogen infecting you, to how bad the initial disease is, to your overall health, and your age. All of this makes predicting what might happen with COVID challenging.

Understanding the spectrum of vaccine efficacy measures
Phase III covid-19 vaccine efficacy trials have returned encouraging results, exceeding the 50% efficacy threshold specified by the World Health Organization (WHO) and the Food and Drug Administration (FDA). Multiple vaccines are now available for use. These phase III trials address the central question of a vaccine’s effect on a meaningful clinical outcome. In nearly all of the trials, the primary aim is to measure efficacy against laboratory confirmed symptomatic disease, including mild symptoms. But this is not the only endpoint that policy makers and individuals care about when making decisions. In fact, we can think about it as one measure of vaccine efficacy that lies alongside others on a spectrum.

Canada vaccine panel recommends 4 months between COVID doses
A national panel of vaccine experts in Canada recommended Wednesday that provinces extend the interval between the two doses of a COVID-19 shot to four months to quickly inoculate more people amid a shortage of doses in Canada. A number of provinces said they would do just that. Prime Minister Justin Trudeau also expressed optimism that vaccination timelines could be sped up. And Health Canada, the country’s regulator, said emerging evidence suggests high effectiveness for several weeks after the first dose and noted the panel’s recommendation in a tweet. But two top health officials called it an experiment.
