COVID-19 Vaccine Information

Who is Currently Eligible for the COVID-19 Vaccine?

Following FDA Emergency Use Authorization and approval by the CDC, all persons in the United States 12 years of age and older are eligible to receive the Pfizer COVID-19 vaccine. Persons 18 years of age and older are eligible to receive the Moderna vaccine or the Johnson & Johnson vaccine.

Booster Shots

The FDA has issued emergency use authorization and the CDC has issued guidelines for booster shots of the Pfizer COVID-19 vaccine only for certain groups, including:

  • People 65 and older.
  • Adults 18 and older who are at high risk of severe COVID-19 infection because of health conditions.
  • Adults 18 and older who are at high risk of exposure due to their jobs or living arrangements.

People in these groups may receive a booster shot no sooner than 6 months after their second Pfizer vaccination. For detailed information about these recommendations, visit

University Health is administering Pfizer booster shots Monday - Friday, 10 a.m. - 6 p.m. on the upper level of Wonderland of the Americas, 4522 Fredericksburg Rd. Please enter from the upper level exterior entrance on the west (Fredericksburg Road) side of the mall, as the mall escalators are currently not functioning. Walk-ins are welcome. 

Important information if you are planning to get a Pfizer booster shot:

  • You must wait 6 months after you receive your 2nd dose of Pfizer. Please check your vaccination card. We cannot give it earlier. Anyone who received a vaccination through University Health can access their vaccine record through their MyChart account.
  • You must bring your vaccination card with you if you did not get your 1st and 2nd doses of Pfizer from University Health. We cannot give you a booster shot without proof that you received two doses of the Pfizer vaccine.
  • Only Pfizer COVID-19 vaccines are authorized. We cannot give you a booster if you received the Moderna vaccine.

Third Doses

Following CDC recommendations, University Health is currently offering 3rd dose shots of the Pfizer and Moderna COVID-19 vaccines for persons who are moderately to severely immunocompromised.

According to the CDC, this group includes some people receiving cancer treatments, organ and stem cell transplant recipients, persons with severe immunodeficiency or untreated HIV infection, or those taking medications that may suppress the immune system. These people may not have had a strong immune response to the vaccine, so the CDC recommends a third dose.

The CDC recommends immunocompromised persons receive their 3rd dose shot no sooner than four weeks after their 2nd dose. 

Free COVID-19 Vaccinations 

We offer the Pfizer and Moderna vaccines free of charge on a walk-in basis at several of our pharmacy locations.

An adult family member or guardian must accompany children in order to provide written consent for the vaccination. Proof of age is not required. 

Persons coming to receive a booster shot must bring their vaccine card or log on to their MyChart account to show which vaccine they have already received and when they were vaccinated. To ensure safety, booster doses will not be offered earlier than the time intervals authorized by the FDA and recommended by the CDC.

We encourage you to learn more about what to bring and what to expect after your vaccination.
