Updated (Bivalent) Booster Information

The virus that causes COVID-19 has changed over time. The different versions of the virus that have developed over time are called variants. Two COVID-19 vaccine manufacturers, Pfizer and Moderna, have developed updated (bivalent) COVID-19 boosters.

The updated (bivalent) boosters are called “bivalent” because they protect against both the original virus that causes COVID-19 and the Omicron variant BA.4 and BA.5.

Previous boosters are called “monovalent” because they were designed to protect against the original virus that causes COVID-19. They also provide some protection against Omicron, but not as much as the updated (bivalent) boosters.

Please visit the CDC's website for references on staying up to date on your booster.
