Pfizer  2020.11.20

Pfizer Inc. and BioNTech SE announced they will submit a request today to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) of their mRNA vaccine candidate, BNT162b2 against SARS-CoV-2, which will potentially enable use of the vaccine in high-risk populations in the U.S. by the middle to end of December 2020.

The submission is based on a vaccine efficacy rate of 95% (p<0.0001) demonstrated in the companies’ Phase 3 clinical study in participants without prior SARS-CoV-2 infection (first primary objective) and also in participants with and without prior SARS-CoV-2 infection (second primary objective), in each case measured from 7 days after the second dose. The first primary objective analysis was based on 170 confirmed cases of COVID-19. This submission also is supported by solicited safety data from a randomized subset of approximately 8,000 participants ≥18 years of age and unsolicited safety data from approximately 38,000 trial participants who have been followed for a median of two months following the second dose of the vaccine candidate. The submission also includes solicited safety data on approximately 100 children 12-15 years of age. Approximately 42% of global participants and 30% of U.S. participants in the Phase 3 study have racially and ethnically diverse backgrounds, and 41% of global and 45% of U.S. participants are 56-85 years of age. To date, the Data Monitoring Committee (DMC) for the study has not reported any serious safety concerns related to the vaccine.
