FDA approved Pfizer and BioNTech's updated Comirnaty COVID-19 vaccine targeting the XFG variant.
What this means
Comirnaty is an mRNA vaccine that uses genetic instructions to teach the body to make the SARS-CoV-2 spike protein and build immunity to COVID-19. Today's FDA action clears an updated version of the vaccine, adapted to target the XFG strain of the virus. This updated vaccine could help maintain protection as the virus continues to evolve.
