The United States must stick to a two-dose strategy for the Pfizer-BioNTech and Moderna Covid-19 vaccines, top U.S. infectious disease official Anthony Fauci told the Washington Post newspaper.
Public Health England (PHE) published real-world analyses of people in the U.K. who had received the first shot of the Pfizer-BioNTech Covid-19 vaccine, with the data – which were published in The Lancet – showing that there was a decrease of about 70 percent in infections among healthcare workers after the first shot.
Drug developer Novavax Inc. completed enrolling 30,000 volunteers in a late-stage study of the company’s Covid-19 vaccine in the United States and Mexico.
The United States reported a 23% drop in new cases of Covid-19 and a 16% fall in the number of people hospitalized with the virus for the week ended Feb. 14, with both figures declining for a fifth week in a row.
Less than one week after posting a positive first-look at Phase III vaccine data, Maryland-based Novavax began the rolling review process for authorization of NVX-CoV2373 in the United Kingdom, Canada and the United States.
Almost all people previously infected with Covid-19 have high levels of antibodies for at least six months that are likely to protect them from reinfection with the disease, results of a major UK study showed.
Novavax Inc. expects to produce up to 150 million Covid-19 vaccine doses monthly by May or June, the company’s chief executive told Reuters, a day after reporting interim data that showed its shot to be 89% effective in a UK trial.
Novavax Inc. said the company’s coronavirus vaccine was 89.3% effective in preventing Covid-19 in a trial conducted in the United Kingdom, and was nearly as effective in protecting against the more highly contagious variant first discovered in the UK, according to a preliminary analysis.
The data continues to come in on the various Covid-19 variants, and so far the news is pretty good, according to BioSpace.
Severe Covid-19 infections are beginning to abate in many parts of the United States even as the death toll mounts, signaling an end to the pandemic’s post-holiday surge and prompting some states to ease public health restrictions.
