Booster Shots

We have begun to administer third doses of the Covid vaccine (Moderna or Pfizer) only to immunocompromised people. Learn more about who is eligible for a COVID-19 booster shot.

We hope to begin administering booster shots this fall for non-immunocompromised people. These doses will be administered 8 months after the second dose of a Pfizer or Moderna vaccine. At this time, a booster dose is not recommended for people that received the Janssen (Johnson & Johnson) vaccine. Learn more about the COVID-19 vaccine booster shot.
