The Biden administration’s haste to roll out an eight-month COVID-19 vaccine booster program next week is bumping up against the reality of the data and the regulatory process.
LONDON – The U.K. government has accepted the recommendation of medical experts and will begin the rollout of COVID-19 boosters from next week, using mRNA vaccines only. That follows data from the U.K. Cov-Boost trial, looking at combinations of initial and booster doses. The results showed Pfizer Inc./Biontech SE’s and Moderna Inc.’s products generated the best immune responses, regardless of which vaccine was administered initially.
The Biden administration may have jumped ahead of the FDA review when it announced last month that it planned to roll out COVID-19 boosters by Sept. 20, but that’s not likely to happen when it comes to the timing of vaccines for young children.
The Biden administration’s plan to roll out COVID-19 boosters by Sept. 20 could get pushed back – pending the outcome of an FDA advisory committee meeting and how quickly the FDA acts on the adcom’s recommendation. Peter Marks, director of the FDA's Center for Biologics Research and Evaluation, announced Sept. 1 that the agency will convene its Vaccines and Related Biological Products Advisory Committee for a virtual meeting Sept. 17.
Higher antibody titer levels were found in participants receiving two doses of Moderna Inc.’s COVID-19 vaccine compared to those receiving the Pfizer Inc.-Biontech SE vaccine, according to a research letter published in JAMA.
The CDC’s Advisory Committee on Immunization Practices (ACIP) heard a safety update on COVID-19 vaccines, took up the matter of booster shots, and voted on whether to recommend the vaccine from Pfizer Inc. and Biontech SE for people 16 and older, now that it’s fully licensed. Under an emergency use authorization, the vaccine can be given to people 12-15 years old.
As many lower and middle-income countries continue to scramble for COVID-19 vaccine doses, which are largely being manufactured in Europe and the U.S., their own regulatory rules may be getting in the way in some instances.
The quiet cancellation of an Aug. 24 meeting in which the U.S. CDC’s Advisory Committee on Immunization Practices (ACIP) was supposed to discuss COVID-19 vaccine boosters is raising more questions about whether the Biden administration got ahead of the data with its Aug. 18 announcement that it planned to roll out mRNA booster shots to adults beginning next month.
The FDA has granted full approval to Pfizer Inc.’s COVID-19 vaccine in a move that is hoped will convince unvaccinated citizens that the shot is safe and effective. The mRNA vaccine, which will be branded as Comirnaty and was first developed by Germany’s Biontech SE, has been available since Dec. 11 last year under an emergency use authorization (EUA) and is the first to receive the FDA’s full endorsement.
The Biden administration’s rollout of a COVID-19 booster plan before the FDA has even approved a booster admittedly is a “judgment call,” U.S. health officials acknowledged Aug. 18. But rather than a judgment call, “the introduction of booster doses should be evidence-driven and targeted to the population groups in greatest need,” the World Health Organization advised in an interim statement issued a week before the White House COVID-19 Response Team’s announcement.
