As members of the White House COVID-19 Response Team talk about COVID-19 boosters as if they are a fait accompli for Americans even before the FDA completes its evaluation of the data, the controversy continues to roil around the need for another vaccine dose.
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.
Chinese companies are finding that their COVID-19 vaccines are effective as booster shots and against variants of the virus, as data from more studies emerge. Those who have received the third dose of Sinovac Biotech Ltd.’s COVID-19 vaccine, Coronavac, showed 2.5-fold higher neutralizing potency against the Delta variant, compared to COVID-19 convalescents and two-dose vaccinees.
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.

LONDON – Conflicting data from around the world on the extent to which the Delta variant of SARS-CoV-2 is reducing the effectiveness of vaccines is generating uncertainty over the need, or not, for booster programs.

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.
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.
