San Antonio's Alamodome will be a COVID-19 Mass Vaccine Site

Updated as of January 15th: The San Antonio Metro Health District has received another 9,000-dose shipment of the Pfizer COVID-19 vaccines and will begin booking appointments today for the Alamodome next week. WellMed has also received another 9,000 doses that will be distributed at two City of San Antonio senior centers next week.

To avoid the overwhelming rush of residents seeking appointments that occurred with the first series of Alamodome appointments, the City of San Antonio will make appointments available on a rolling basis. Today’s appointments will be for approximately 2,000 slots on Monday; tomorrow, the City will make available 2,000 slots for Tuesday, and so on. The registration system will continue to reopen as appointments become available due to cancellations. 

“With more frequent registration opportunities, we hope to spread out the demand and give eligible residents more chances to book an appointment for the vaccine,” said Assistant City Manager Dr. Colleen Bridger. “The vaccine continues to be scarce, so please be patient. We expect vaccine supplies to improve over the next several weeks.”

Appointments for the Alamodome can be made by visiting Those with internet access should use the website to sign up. Some slots will be reserved for those without internet access, who may call 311 and select option 8 to book an appointment. A busy signal indicates that all operators are taking other calls, and callers should try again.

Tomorrow, Saturday, January 16th, 2021, WellMed will re-open phone lines at 8 a.m. to take appointments for another 9,000 doses of the COVID-19 vaccine (Moderna) it has received from the Texas Department of State Health Services. WellMed, in partnership with the City of San Antonio (COSA), is operating two mass vaccination clinics for the public at WellMed Charitable Foundation senior centers on the South Side and West Side.

The number to call is 1-833-968-1745. The hotline will be open from 8 a.m. to 8 p.m. daily until 9,000 more appointments are filled. You MUST schedule an appointment over the phone to receive the vaccine. Walk-ins will not be accepted.

Due to the high volume of phone calls, callers who cannot get through to a WellMed customer service representative should keep calling back. If phone lines are overwhelmed, you will hear one of two messages:

On a cell phone: “The line you are trying to reach is out of service.”

On a landline: “All circuits are busy. Please try your call later.”

If you are cut off after getting through to the recorded greeting, it means all operators are on calls. It is also possible the call will not go through at all. These all are issues with the phone service provider.

At this time, people who qualify in the 1A or 1B categories (healthcare workers, anyone age 65 and older, and adults 18 and older with a chronic condition) are eligible for COVID-19 vaccinations at these clinics. 

Who can get the vaccine?

According to state and federal guidelines, those currently eligible to receive the vaccine include healthcare workers, residents of long-term care facilities, anyone over age 65, and anyone 18-years or older with a chronic medical condition. Chronic medical conditions include cancer, kidney disease, COPD, heart conditions, solid organ transplant recipients, obesity, pregnancy, sickle cell disease, and type two diabetes.
