Use of COVID-19 Vaccines in the United States
Interim Clinical Considerations
FDA has approved and authorized 2024–2025 Moderna and Pfizer-BioNTech COVID-19 vaccines. CDC recommendations for use of these vaccines in people ages 6 months and older can be found below.
The 2023–2024 Novavax COVID-19 Vaccine remains authorized but is no longer available in the United States as all doses have expired. Accordingly, at this time, CDC recommendations for use of Novavax COVID-19 Vaccine have been removed from the Interim Clinical Considerations. This page will be updated if FDA approves or authorizes additional 2024–2025 COVID-19 vaccines.
