Starting Sept. 29, San Antonio Metro Health will offer booster shots of the Pfizer vaccine to people age 65 and older as well as adults age 18 and older who are considered to be at high risk of severe illness from COVID-19.

This decision follows recent approval by the U.S. Food and Drug Administration and recommendation by the Centers for Disease Control & Prevention.

Eligible individuals can get a booster shot at the Alamodome drive-thru vaccine clinic from noon-8 p.m. Wednesdays through Fridays. No appointment is needed; however, individuals can also visit covid19.sanantonio.gov to make an appointment. Booster doses will also be given at all Metro Health vaccine pop-up clinics.

People who go to the Alamodome for a booster shot must bring their immunization cards to confirm completion of their vaccine series to receive a third dose of the Pfizer vaccine for extra protection from COVID-19. The third dose is to be given six months after a person has been fully vaccinated, according to CDC guidance.

However, the city did not say if people who have only received the Moderna or Johnson & Johnson vaccine are prohibited from getting the Pfizer booster.



“Although we will provide booster shots to eligible people at the Alamodome, we want to remind the public they can get a booster shot at their doctor’s office, pharmacies and from other medical providers,” Metro Health Director Claude Jacob said.

“I also want to remind everyone of the importance of beginning their vaccine series. You are 10 times more likely to be hospitalized due to COVID-19 if you are unvaccinated. Please take the time to get vaccinated to protect yourself and your loved ones.”

Holding a COVID-19 briefing Sept. 28, local officials said the community positivity rate has dropped to 5% with other public health indicators trending in a positive direction.

On Sept. 22, the FDA approved booster shots for people age 65 and older and other adults who are at risk of serious illness or complications from the coronavirus.


The recommendation by the CDC’s Advisory Committee on Immunization Practices supporting the FDA’s decision followed Sept. 23.

The CDC recommends booster shots for the following:

  • Individuals age 65 and older and residents in long-term care settings are urged to receive a booster shot of the Pfizer vaccine at least six months after their Pfizer primary series.
  • People ages 50-64 with underlying medical conditions are encouraged receive a booster shot of the Pfizer vaccine at least six months after their Pfizer primary series.
  • Individuals ages 18-49 with underlying medical conditions may receive a booster shot of the Pfizer vaccine at least six months after their Pfizer primary series based on their individual benefits and risks.
  • People ages 18-64 who are at increased risk for COVID-19 exposure and transmission because of occupational or institutional setting may receive a booster shot of the Pfizer vaccine at least six months after their Pfizer primary series based on their individual benefits and risks.

Booster shots are not eligible for Metro Health’s H-E-B gift card incentive program.
