Am I eligible for a booster shot?

The COVID-19 vaccines authorized and approved in the U.S. remain highly effective, especially against severe illness and death. Recently, the Centers for Disease Control and Prevention updated recommendations for booster shots for some people.

If you received the Johnson and Johnson vaccine:
The Centers for Disease Control and Prevention recommends a booster shot for everyone age 18 and older vaccinated at least two months ago with the Johnson and Johnson vaccine. You may receive any of the three COVID-19 vaccines available in the U.S for your booster.

If you received the Pfizer or Moderna vaccines:
You may receive a booster if you completed your initial vaccine series at least six months ago and are age 18 and older.

When to get a booster:
At least 6 months after completing your primary COVID-19 vaccination series. You can “mix and match” your vaccine for your booster dose, or get a different booster vaccine than the one you received initially.

If you received vaccines on the WHO’s Emergency Use Listing (EUL) and are 18 or older:
You may receive a booster of the Pfizer vaccine 6 months after completing your initial dose series. Booster doses of Pfizer, Moderna and Johnson and Johnson vaccines are available by appointment at UHS to UW–Madison employees and students. Learn more and schedule an appointment here. Information about boosters and additional doses is changing quickly. Talk to your health care provider if you have questions.

Note that boosters are different from the additional doses recommended for immunocompromised people. Learn more.
