On Aug. 22, 2022, Pfizer and BioNTech announced they had 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 individuals 12 years of age and older.

The application follows guidance from the FDA to include clinical data from the companies’ bivalent Omicron BA.1-adapted vaccine and pre-clinical and manufacturing data from the companies’ bivalent Omicron BA.4/BA.5-adapted vaccine to address the continued evolution of SARS-CoV-2. Pending authorization, the Omicron BA.4/BA.5-adapted bivalent vaccine will be available to ship immediately.

A conditional marketing authorization application has also been initiated with the European Medicines Agency (EMA) for the Omicron BA.4/BA.5-adapted bivalent vaccine and is expected to be completed in the coming days.
