Pfizer-BioNTech gets USFDA nod for COVID vaccine Comirnaty for adolescents 12 through 15 years of age

The approval is based on data from a Phase 3 clinical trial of 2,260 participants 12 through 15 years of age. A two-dose primary series of the vaccine (30-µg dose) elicited SARS-CoV-2–neutralizing antibody geometric mean titers (GMTs) of 1,239.5, demonstrating strong immunogenicity in a subset of adolescents one month after the second dose. This compared well (was non-inferior) to GMTs elicited by participants aged 16 to 25 years old (705.1 GMTs) in an earlier analysis. In the trial, a two-dose primary series of the vaccine (30-µg dose) was also 100% effective (95% confidence interval [CI, 87.5, 100.0]) in preventing COVID-19, measured between a week and more than four months after the second dose. During this time, all 30 cases of confirmed symptomatic COVID-19 were in the placebo group (n=1,109) and no cases were in the COMIRNATY group (n=1,119). The only SARS-CoV-2 variant of concern identified from the confirmed COVID-19 cases in this age group was Alpha as the efficacy analysis was conducted between November 2020 and May 2021, which was before the Delta and Omicron surges. No cases of severe disease occurred in either the COMIRNATY or placebo group. The adverse event profile was generally consistent with other clinical data for the vaccine, with a favorable safety profile observed across 6 months of safety follow-up data after the second dose.

Pfizer and BioNTech also filed these data with the European Medicines Agency (EMA) and other regulatory authorities around the world.

COMIRNATY is now the COVID-19 vaccine approved by the FDA as a two-dose primary series for individuals 12 years and older. An EUA for a primary series in U.S. adolescents ages 12 through 15 years was previously granted in May 2021 based on initial data from the same pivotal Phase 3 clinical trial. Longer-term follow-up data, announced in November 2021, confirmed the safety and effectiveness of COMIRNATY in adolescents 12-15 years of age and were required for licensure. In the European Union the conditional marketing authorization in this age group was granted by EMA in August 2021.

COMIRNATY was previously FDA approved for individuals 16 years and older in August 2021. Pfizer and BioNTech have also submitted a sBLA to the U.S. FDA to extend the approval of COMIRNATY to include booster doses for individuals ages 16 years and older, who are currently authorized under EUA.

COMIRNATY, which is based on BioNTech's proprietary mRNA technology, was developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder in the United States, the European Union, the United Kingdom, Canada and other countries, and the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer) and other countries. Pfizer and BioNTech also are pursuing regulatory approvals for this age group in other countries where emergency use authorizations or equivalents have been granted.

COMIRNATY (COVID-19 Vaccine, mRNA) is a vaccine approved for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 12 years of age and older.
