COVID-19 3rd Dose Vaccinations and Boosters - Updated October 15, 2021

UT Health Austin is now offering 3rd doses of Pfizer COVID-19 vaccine to eligible immunocompromised patients (per CDC guidelines here) 28 days following their 2nd dose of Pfizer COVID-19 vaccine. We are also offering Booster doses of Pfizer COVID-19 vaccine to eligible patients (per CDC guidelines here) 6 months following their 2nd dose of Pfizer COVID-19 vaccine. Both 3rd doses for the immunocompromised and Booster doses for those who meet eligibility are available by appointment or walk-in.

Though many news and other sources call this 3rd dose of vaccine a booster vaccination, it actually helps people with certain medical conditions achieve a level of protection that the standard two-dose vaccination provides for non-immunocompromised individuals.

While current evidence indicates that fully vaccinated individuals who are not immunocompromised have substantial protection from serious illness and/or hospitalization from the Delta variant of the COVID-19 virus, we are all well-advised to continue wearing masks and maintaining personal safety and distancing measures to reduce our risk of exposure and/or transmission as much as possible.

Please select from the forms below to request a 1st or 2nd dose of Pfizer COVID-19 vaccine.
