  • Novavax

COVID-19 Vaccines: 2023–2024 Updated, Bivalent, and Original

2023–2024 updated COVID-19 vaccines

As of September 12, 2023, the 2023–2024 updated Pfizer-BioNTech and Moderna COVID-19 vaccines were recommended by CDC for use in the United States.

The 2023–2024 updated COVID-19 vaccines more closely targets the XBB lineage of the Omicron variant and could restore protection against severe COVID-19 that may have decreased over time. We anticipate the updated vaccines will be better at fighting currently circulating variants.

Novavax’s updated COVID-19 vaccine is currently under review by the U.S. Food and Drug Administration (FDA) for emergency use authorization (EUA) in individuals aged 12 and older.

2022–2023 Bivalent vaccines

As of September 11, 2023, the bivalent Pfizer-BioNTech and Moderna COVID-19 vaccines are no longer available for use in the United States.

The 2022–2023 bivalent vaccines were designed to protect against both the original virus that causes COVID-19 and the Omicron variants BA.4 and BA.5. Two COVID-19 vaccine manufacturers, Pfizer-BioNTech and Moderna, had developed bivalent COVID-19 vaccines.

Original vaccines

As of April 18, 2023, the original Pfizer-BioNTech and Moderna COVID-19 vaccines are no longer available for use in the United States.

As of May 6, 2023, J&J/Janssen COVID-19 vaccine  is no longer available for use in the United States.

Previous COVID-19 vaccines were called “original” because they were designed to protect against the original virus that causes COVID-19.

Getting Vaccines If You Recently Had COVID-19

If you recently had COVID-19, you still need to stay up to date with your vaccines, but you may consider delaying your vaccine by 3 months.

Reinfection is less likely in the weeks to months after infection. However, certain factors could be reasons to get a vaccine sooner rather than later, such as:
