COVID-19 Vaccine Update Guide
Eligibility information about booster shots and updated versions of the COVID-19 vaccine
If you have not received a COVID-19 vaccine in the past 2 months, get an updated COVID-19 vaccine to protect yourself against new variants of COVID-19.
Updated (Bivalent) Vaccine
The updated (bivalent) vaccines are called “bivalent” because they protect against both the original virus that causes COVID-19 and the Omicron XBB variants.
Previous vaccines and 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) vaccines.
When Are You Up to Date?
You are up to date with your COVID-19 vaccines if you have completed a COVID-19 vaccine primary series and received the most recent dose recommended for you by CDC.
COVID-19 vaccine recommendations are based on three things:
- Your age
- The vaccine you first received, and
- The length of time since your last dose
People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines.
You are still up to date if you receive all COVID-19 vaccine doses recommended for you and then become ill with COVID-19. You do not need to be immediately revaccinated or receive an additional booster.
If you recently had COVID-19, you may consider delaying your next vaccine dose (whether a primary dose or booster) by 3 months from when your symptoms started or, if you had no symptoms, when you first received a positive test.
