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 booster dose recommended for you by CDC.

COVID-19 vaccine recommendations are based on three things:

  1. Your age
  2. The vaccine you first received, and
  3. 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.

The COVID-19 vaccines generally remain very effective against severe illness and death. But over time, they do decrease in effectiveness against infection. Receiving a booster shot makes you less likely to get infected or experience mild illness from the virus.

CDC and CT DPH recommend that everyone 5 years and older get a bivalent booster shot at least 2 months after completing a primary series or an original (monovalent) booster dose.
