COVID-19 Vaccine Availability

The CDC recommends COVID-19 vaccination for everyone 6 months and older. FDA-approved or authorized COVID-19 vaccines are currently available to all U.S. citizens and residents. Visit the CDC website for more information.

  • COVID-19 vaccines are safe, effective, and free.
  • Getting the vaccine can reduce the risk of severe disease, hospitalizations and long-term complications for COVID-19
  • For children, the vaccine can also curb community transmission and reduce disruptions to in-person learning activities.

Getting the COVID-19 Vaccine

Vaccination Slot Updates

As of April 23, the 71st Medical Group is offering COVID-19 vaccine walk-in hours from 8:00 a.m. to 11:00 a.m. on Thursdays and Fridays to all persons with base access, age 18 years and older.  It is not required to have beneficiary medical status. Those who received their first shot of Moderna vaccine may schedule their second COVID-19 vaccine (Moderna only) when they become due -- 28 days or later from first vaccine.

There is no need to schedule an appointment for vaccine within walk-in hours listed.

To schedule an appointment outside of these hours, call the Vance Clinic appointment line and 580-213-7416, and immediately select Option 1, 1, 1. The appointment line is normally open for calls from 7:00 a.m. to 4:30 p.m., Monday through Friday.

Stay Up to Date with COVID-19 Vaccines and Boosters

You are up to date with your COVID-19 vaccines if you have completed a COVID-19 vaccine primary series and received the most recent bivalent dose recommended for you by the CDC.
Vaccine recommendations are based on your age, the vaccine you first received, and time since last dose. People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines.
Updated bivalent vaccines are now recommended for anyone six months old and older. Per the CDC, bivalent mRNA vaccines are not authorized at this time for primary series doses with the following exception: children ages six months to four years who receive two primary series doses of a monovalent Pfizer-BioNTech vaccine should receive a bivalent Pfizer-BioNTech vaccine as their third primary series dose. Consult with your primary care manager on availability and the best options to help protect you and your loved ones from severe illness, hospitalization, or death from COVID-19.
