Expanded FDA Emergency Use Authorization of COVID-19 Vaccine booster to include individuals 18 and older.- Pfizer + BioNTech SE.

In October 2021, the companies announced positive topline results from the trial showing that a booster dose administered to individuals who previously received the Pfizer-BioNTech primary two-dose series demonstrated a relative vaccine efficacy of 95% when compared to those who did not receive a booster. Thus far, these are the first and only efficacy data disclosed from any randomized, controlled COVID-19 vaccine booster trial. The adverse event profile was generally consistent with other clinical safety data for the vaccine, with no new safety concerns identified.

A booster dose of the Pfizer-BioNTech COVID-19 Vaccine was previously authorized by the FDA for emergency use after completion of a primary series in individuals 65 years of age and older, individuals 18 through 64 years of age at high risk of severe COVID-19, and individuals 18 through 64 years of age with frequent institutional or occupational exposure to SARS-CoV-2, as well as eligible individuals who have completed primary vaccination with a different authorized COVID-19 vaccine.
