According to reports, on the same day, the FDA Vaccines and Biologicals Advisory Committee reviewed the data submitted by Pfizer on its booster injections, and finally rejected the general public's plan for booster injections with a 16 to 2 vote.
Committee members expressed doubts about the safety of booster needles in young people and adolescents, and complained about the lack of data on the safety and long-term efficacy of boosters.
