Schedule COVID-19 Vaccine: Same-day available | Primary Series and Booster Shot Recommendations
Tuesday, April 5, 2022
Primary Series
A person is considered “fully vaccinated” two weeks after receiving all recommended doses in the primary series of their COVID-19 vaccination. Your primary series doses depend on your age, your health status, what vaccine you first received, and when you first got vaccinated. Review the CDC’s webpage and recommendation chart to understand how to stay up-to-date with your COVID-19 vaccines.
Booster Shots
Pfizer booster shots are approved for everyone 12 years old and older, and some people are eligible for a second booster shot. The CDC chart below outlines who should get a booster, when to get a booster and which booster you should get. Schedule your booster shot online.

Mixing and Matching Vaccine Brands
mRNA vaccines (Pfizer and Moderna) are preferred, but J&J/Janssen COVID-19 vaccines may be considered in some situations. UT Health San Antonio primarily provides Pfizer vaccines. Vaccines can be scheduled online.
Established primary care patients, 18 years and older, may schedule a Moderna vaccine by calling their provider's office or schedule using MyChart. We do not offer J&J vaccines.
Vaccine and Booster Shot Recommendations for Immunocompromised Individuals
Those who are moderately or severely immunocompromised (have a weakened immune system) are at increased risk of severe COVID-19 illness and death. Their immune response to the COVID-19 vaccination may not be as strong as in people who are not immunocompromised. To stay up-to-date, the CDC recommends:
Schedule your COVID-19 shot online
UT Health San Antonio primarily provides Pfizer vaccine. Established primary care patients may schedule a Moderna vaccine by calling their UT Health San Antonio primary care location or using MyChart to schedule.
If you are not an established patient and want a Moderna or J&J/Janssen COVID-19 vaccine, check availability with your primary care provider, local pharmacy or community mass vaccination site. Find a vaccine location at Vaccines.gov.
