Oxford releases new data on vaccine efficacy against UK strain, Johnson & Johnson seeks FDA approval, and the US Senate passes a key resolution for coronavirus aid.The Oxford-AstraZeneca vaccine protects against the UK variant, while the FDA drafts new plans for dealing with mutations.
For months, these researchers had been periodically doing similar genomic surveillance work to keep tabs on the dozens of strains of SARS-CoV-2 that were circulating around the country, looking for any problematic mutations in the virus’s spike protein.
Biden gets to work on the pandemic, the CDC adjusts vaccine guidelines, and death tolls rise worldwide.CDC data suggests the country has already reached a pace of approximately one million vaccines administered per day several times in the last few weeks, but it also indicates that states and cities are administering fewer than half of the doses that they’ve received.
An FDA advisory panel authorizes the first vaccine, the US hits grim milestones, and cases rise worldwide.On Thursday, as cases and hospitalization rates rose further, the country hit a grim milestone: The total number of Americans who have died from Covid-19 surpassed the number of US service people who died in combat during World War II.
Trust in vaccines grows slightly, distribution faces challenges, and legislators plan for the next stage.
On Wednesday, one of the world’s most prestigious medical journals published what many took to be a disheartening result: According to some headlines, a 6,000-person randomized controlled trial in Denmark had found that wearing a mask does not offer any clear protection from being infected with the SARS-CoV-2 coronavirus.

Americans prepare for another surge in cases, vaccine and treatment approval moves forward, and new partnerships curb coronavirus misinformation.This news comes approximately a week after a massive international trial found that remdesivir does not prevent deaths among patients with severe cases with Covid-19.
Treatment and vaccine trials are halted, the US forges ahead with its decentralized response, and new revelations about American society and institutions underscore the deadly toll of the virus.
President Trump tests positive, lawmakers consider new approaches to contact tracing and testing, and America’s largest school districts navigate reopening.Thus far, contact-tracing apps haven’t done much to stop the spread of Covid-19 in the US, as different states coordinate patchwork responses and the federal government doesn’t weigh in.
In fact, Covid-19’s incubation period probably means that the president and his wife could have been infectious at the Cleveland debate with Biden.
President Trump is isolating himself in the White House, having tested positive for the coronavirus last night.Emily Gurley, an epidemiologist at Johns Hopkins School of Public Health, says the first step is to work out when Trump likely became infectious.
It helped that back in December, while the coronavirus was just starting to spread inside the Chinese city of Wuhan and the World Health Organization was still months away from declaring a global pandemic, the Taiwanese government deployed its equivalent of the US Defense Production Act to produce masks for its citizens.
More vaccines enter Phase III trials, researchers continue to learn about the long-term impacts of Covid-19, and risk calculation becomes increasingly difficult as the country reopens.New tools aim to help you calculate risk as cases rise and the country reopens.
What was not at at all normal: The group was launching an international network to detect pathogens that can jump from wildlife to the human population, a field of inquiry that’s become politicized since the coronavirus pandemic began—and they were doing it with federal money, even though the United States government has been the source of the politicization.
