Texas MedClinic is now offering the COVID-19 Vaccine to the public at limited locations in San Antonio. All patients must register through the online system. Vaccine doses are limited quantity per day.

No walk-ins will be accepted for COVID-19 Vaccines.

Due to the pause (initiated by the CDC) of the Janssen vaccine, many Moderna doses have been reallocated and delayed. Unfortunately, this has caused a delay in the 2nd doses scheduled between April 22nd and 25th. Be aware all appointments are being moved to the following week, starting on April 26th. Vaccines being rescheduled will be notified either by text or phone. We apologize for the inconvenience.
