COVID-19 Vaccine (Comirnaty, BNT162b2) Description For 2022

BioNTech S.E. and Pfizer, Inc. co-developed the U.S. FDA Approved Pfizer-BioNTech COVID-19 Vaccine (BNT162b2) vaccine to prevent severe COVID-19 caused by the SARS-CoV-2 beta coronavirus. The vaccine is based on BioNTech proprietary messenger RNA (mRNA). The U.S. FDA Approved the Pfizer-BioNTech COVID-19 Vaccine on Aug. 23, 2021.

Known globally as Comirnaty, the vaccine is a nucleoside-modified RNA formulated in lipid nanoparticles and encodes an optimized SARS-CoV-2 full-length spike protein antigen. Comirnaty contains a molecule with instructions for producing a protein from the SARS-CoV-2 virus. Comirnaty revenues were approximately $34 billion, which reflects favorable operational updates compared to prior guidance, partially offset by unfavorable incremental impacts from foreign exchange. This guidance includes doses expected to be delivered in fiscal 2022(5), primarily under contracts signed as of mid-October 2022.

Germany-based Biopharmaceutical New Technologies (BioNTech.E.) is the Marketing Authorization Holder in the USA, Europe, and the UK and the holder of emergency use authorizations or equivalents in the U.S. (jointly with Pfizer), Canada, and other countries. Biopharmaceutical New Technologies is an immunotherapy company pioneering novel therapies for cancer and other serious diseases.
