Once the CDC accepts the recommendation of its Advisory Committee on Immunization Practices (ACIP), the COVID-19 vaccine regimen, at least for the Pfizer Inc.-Biontech SE vaccine, will include a booster dose for everyone 12 and older. ACIP voted 13-1 at a Jan. 5 emergency meeting to recommend the booster dose for 12- to 17-year-olds at least five months after a primary series of the Pfizer vaccine.
LONDON – There was a substantial fall in neutralization titers against the Omicron variant of SARS-CoV-2 in the stored sera of people who had received two doses of either Astrazeneca plc’s or Pfizer Inc./Biontech SE’s COVID-19 vaccines, with some samples failing to neutralize the virus at all, according to the latest data from the U.K. Com-Cov study.
There is now more clarity on the Omicron variant of SARS-CoV-2, as serum antibodies produced by three doses of the Pfizer Inc.-Biontech SE COVID-19 vaccine have been shown to neutralize it. The data arrived a day after Glaxosmithkline plc and Vir Biotechnology Inc. said the monoclonal antibody sotrovimab retains activity against key mutations of the Omicron variant, including those found in sotrovimab’s binding site.
Former FDA Commissioner Stephen Hahn is being asked to spill the beans on political interference at the U.S. agency during the emergence of COVID-19 last year.
The FDA amended emergency use authorizations (EUAs) for the Moderna Inc. COVID-19 vaccine as well as the shot from Pfizer Inc. and Biontech SE. A single booster dose was green-lighted for people 18 years and older at least six months after finishing the primary regimen with either of the vaccines, or at least two months after getting the Johnson & Johnson shot.
A few hours after the U.S. CDC Advisory Committee on Immunization Practices’ Nov. 2 recommendation to allow children ages 5 through 11 to be administered Pfizer Inc. and Biontech SE’s COVID-19 vaccine, Comirnaty (tozinameran), the agency’s director, Rochelle Walensky, endorsed the recommendation. The recommendation came as the World Health Organization (WHO) expanded the COVID-19 vaccines it recommends in the fight against the pandemic by endorsing Bharat Biotech International Ltd.’s Covaxin.
In a move that had been expected, the CDC’s Advisory Committee on Immunization Practices unanimously recommended the Pfizer Inc.-Biontech SE COVID-19 vaccine as safe and beneficial for children ages 5 through 11. The recommendation, coming from a 14-0 vote, is the committee’s way of reassuring the American public that the vaccine is safe, according to committee member Beth Bell, clinical professor in the School of Public Health at the University of Washington in Seattle.
An ongoing evaluation of heart muscle inflammation risk, a key concern with mRNA COVID-19 vaccines globally, could delay through January 2022 completion of an FDA review of Moderna Inc.'s vaccine in adolescents 12 to 17 years of age. The side effect, called myocarditis, has been a particular concern with regulators, especially for adolescents and young men.
The FDA has granted emergency use authorization (EUA) to the COVID-19 vaccine created by Pfizer Inc.-Biontech SE for use in children ages 5 through 11. This is the first EUA for a COVID-19 vaccine to be awarded for this group of roughly 28 million children in the U.S. and it comes after weeks of lengthy debate among experts about the wisdom of targeting the young demographic.
The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted 17-0, with one abstention, that the benefits of Pfizer Inc.-Biontech SE pediatric formulation of its two-dose COVID-19 vaccine outweigh its risks for children ages 5 through 11. Many of those votes came with caveats, as the VRBPAC members struggled with the unknowns of the vaccine and the fear that schools would mandate its use, even though it would still be considered experimental if the FDA grants it an emergency use authorization.
