After a two-day session of the FDA’s Vaccines and Related Biologic Products Advisory Committee, the U.S. is within days of a long-awaited milestone of having not just one but at least two vaccines available for nearly every American. The VRBPAC voted unanimously, 21-0, June 15 to support amending the emergency use authorizations for both the Moderna Inc. and Pfizer Inc.-Biontech SE COVID-19 mRNA vaccines to allow their use in children 6 months and older.
Up to now, the Pfizer Inc.-Biontech SE COVID-19 vaccine has had a lock on the U.S. pediatric market, for ages 5 to 17, but that could change as early as next week.
Given the safety and efficacy data presented June 7 for Novavax Inc.’s COVID-19 vaccine, NVX-CoV2373, it came as no surprise when the U.S. FDA’s Vaccines and Related Biologic Products Advisory Committee voted 21-0, with one abstention, to support an emergency use authorization for the vaccine, which is already approved and being used in many other countries, including the EU and Canada.
The U.S. FDA’s efficacy bar for COVID-19 vaccines for the youngest children may be lower than the 50% required for the adult vaccines, according to Peter Marks, director of the agency’s Center for Biologics Evaluation and Research.<
When the U.S. FDA convened its Vaccines and Related Biological Products Advisory Committee (VRBPAC) April 6 to advise on a path forward to the next generation of COVID-19 vaccines and boosters, there was a lot of talk about all the unknowns.
"Now is the time to discuss the need for future boosters as we aim to move forward safely, with COVID-19 becoming a virus like others such as influenza that we prepare for, protect against and treat,” the FDA’s Peter Marks said in announcing an April 6 virtual meeting of the Vaccines and Related Biological Products Advisory Committee (VRBPAC).
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.
Given the FDA’s Vaccines and Related Biological Products Advisory Committee’s unanimous vote last month to recommend use of a booster dose of the Pfizer Inc.-Biontech SE COVID-19 vaccine in certain high-risk groups, it came as no surprise when the committee again voted unanimously Oct. 14 for a mirror use of Moderna Inc.’s proposed booster.
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.
While the FDA’s approach to evaluating safety and efficacy in the development and review of COVID-19 vaccines for the U.S. market will be at the center of its Oct. 22 advisory committee meeting, the panel also will be asked to discuss the practicalities, and ethics, of continuing to conduct trials once a candidate has been granted an emergency use authorization.
