Updated vaccines, sometimes called “bivalent” vaccines

The updated vaccines are called “updated” because they protect against both the original virus that causes COVID-19 and the Omicron variant BA.4 and BA.5. Two COVID-19 vaccine manufacturers, Pfizer-BioNTech and Moderna, have developed updated COVID-19 vaccines.

Original vaccines, sometimes called “monovalent” vaccines

Previous COVID-19 vaccines are called “original” because they were designed to protect against the original virus that causes COVID-19. Monovalent vaccines are no longer available. As of April 18, 2023, the original Pfizer-BioNTech and Moderna COVID-19 vaccines are no longer authorized for use by the FDA in the United States. Updated Pfizer-BioNTech and Moderna COVID-19 vaccines are being used for all age groups. As of May 6, 2023, J&J/Janssen COVID-19 vaccine has expired and is no longer available for use in the United States.

New vaccines expected in fall 2023

On June 15, 2023, an FDA advisory committee met to talk about COVID-19 vaccines and additional strains of the COVID-19 virus. They recommended that COVID-19 vaccines should be updated to provide protection against the Omicron variant XBB.1.5 for use by the fall of 2023.
