On Oct. 3, 2023, the U.S. Food and Drug Administration amended the emergency use authorization (EUA) of the Novavax COVID-19 Vaccine, Adjuvanted for use in individuals 12 years of age and older to include the 2023-2024 formula. Individuals 12 years of age and older previously vaccinated with a COVID-19 vaccine (and who have not already been vaccinated with a recently updated mRNA COVID-19 vaccine) are eligible to receive one dose and unvaccinated individuals receive two doses.

Consistent with the totality of the evidence and input from the FDAﾒs expert advisors, the Novavax COVID-19 Vaccine, Adjuvanted, a monovalent vaccine, has been updated to include the spike protein from the SARS-CoV-2 omicron variant lineage XBB.1.5 (2023-2024 formula).
