AbstractBNT162b2 (Comirnaty®; BioNTech and Pfizer) is a lipid nanoparticle-formulated, nucleoside-modified mRNA vaccine for the prevention of the novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. BNT162b2 encodes the SARS-CoV-2 spike protein, the expression of which elicits immune responses against the antigen in recipients. In early December 2020, BNT162b2 received a temporary emergency use authorization (EUA) in the UK and, subsequently, a series of approvals or authorizations for emergency use in Bahrain, Canada, Mexico, Saudi Arabia and the USA. Soon after, BNT162b2 received conditional marketing authorizations in Switzerland (19 December 2020) and the EU (21 December 2020) for active immunization to prevent COVID-19 caused by SARS-CoV-2 in individuals 16 years of age and older. BNT162b2 is administered intramuscularly in a two-dose regimen. This article summarizes the milestones in the development of BNT162b2 leading to these first approvals for the prevention of COVID-19.
