FDA authorises Moderna, Pfizer-BioNTech bivalent COVID-19 vaccines for use as a booster dose
31 August 2022 - Today, the US FDA amended the emergency use authorisations of the Moderna COVID-19 Vaccine and the Pfizer-BioNTech COVID-19 Vaccine to authorise bivalent formulations of the vaccines for use as a single booster dose at least two months following primary or booster vaccination.
The bivalent vaccines, which we will also refer to as “updated boosters,” contain two messenger RNA components of SARS-CoV-2 virus, one of the original strain of SARS-CoV-2 and the other one in common between the BA.4 and BA.5 lineages of the omicron variant of SARS-CoV-2.
