NEW YORK and MAINZ, GERMANY, September 28, 2022 —Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced they have completed a submission to the European Medicines Agency (EMA) for a 10-µg booster dose of the companies’ Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine for children 5 through 11 years of age. This application for a variation of the marketing authorization (MA) to include the Omicron BA.4/BA.5-adapted bivalent vaccine in this age group is supported by safety and immunogenicity data from the companies’ Omicron BA.1-adapted bivalent vaccine, non clinical and manufacturing data from the companies’ 10-µg Omicron BA.4/BA.5-adapted bivalent vaccine, and preclinical data from the companies’ Omicron BA.4/BA.5-adapted bivalent vaccine.

On September 26, the companies also completed a submission to the U.S. Food and Drug Administration (FDA) requesting Emergency Use Authorization (EUA) of a booster dose of an Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine for children 5 through 11 years of age.

In addition, the companies have also initiated a Phase 1/2/3 study (NCT05543616, C4591048) to evaluate the safety, tolerability and immunogenicity of different doses and dosing regimens of the companies’ Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine in children 6 months through 11 years of age. This study is consistent with regulatory guidance and follows the design of the previous Phase 1/2/3 trial to evaluate further options for protection in this age group.

COMIRNATY, which is based on BioNTech’s proprietary mRNA technology, was developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder for BNT162b2 (COMIRNATY®) 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. Submissions to pursue regulatory approvals in those countries where emergency use authorizations or equivalent were initially granted are planned.
