Supplemental BLA Submitted for Pfizer-BioNTech COVID-19 Vaccine for 12- to 15-Year-Olds

Pfizer and BioNTech have submitted a supplemental Biologics License Application to the Food and Drug Administration (FDA) for Comirnaty (COVID-19 vaccine, mRNA) to include individuals 12 to 15 years of age for active immunization to prevent COVID-19.

The application is supported by data from a randomized, placebo-controlled phase 3 trial which included 2228 participants 12 to 15 years of age enrolled in the United States. Participants were randomly assigned to receive either a 2-dose series (30µg per dose) of the Pfizer-BioNTech COVID-19 vaccine (n=1131) or placebo (n=1129).

Findings from data collected between November 2020 and September 2021 showed that the vaccine was 100% effective (95% CI, 87.5-100.0) against COVID-19, measured 7 days through over 4 months after the second dose. There were 30 confirmed symptomatic cases of COVID-19 reported in the placebo group and 0 cases in the vaccine group. 

The safety profile of the vaccine was consistent with that reported in other clinical safety data. There were no serious safety concerns observed in participants with at least 6 months of safety follow-up after the second dose.
