COVID-19 vaccine third doses and booster shots: Who is eligible and how to get one
Time & Date
Thursday, October 21, 2021
Pfizer booster shots are approved for everyone 12 years old and older. The CDC recommends Pfizer booster shots for everyone 12 years or older who received any of the three available COVID-19 vaccines: Pfizer, Moderna and Johnson & Johnson (J&J). Schedule your booster shot now.
Mix and match vaccines: The CDC recommendation allows "mix and match" dosing for booster shots. People may choose which type of booster shot they receive. UT Health San Antonio primarily provides Pfizer vaccines. Vaccines and boosters can be scheduled online.
Our established primary care patients, 18 years and older, can schedule a Moderna booster shot by contacting their provider's office. We are not offering J&J vaccines.
Third doses for immunocompromised individuals: The CDC recommends that people whose immune systems are moderately to severely compromised receive a third dose no sooner than 28 days (or 4 weeks) after completing their second dose of the Pfizer or Moderna vaccine.
Eligibility criteria for booster shots and third doses: The eligibility requirements and time between doses are different for booster shots and for those who are immunocompromised and should receive a third dose.
Here is what you should know about COVID-19 third vaccines and COVID-19 booster shots:
