FDA issues full approval for Pfizer-BioNTech COVID-19 vaccine, now marketed under brand name “Comirnaty”

The United States Food and Drug Administration (FDA) issued full approval, Aug. 23, of the Pfizer BioNTech COVID-19 vaccine, which will now be marketed under the brand name “Comirnaty.” The approval covers prevention of COVID-19 in individuals 16 years of age and older. The vaccine is still approved under the emergency use authorization (EUA) for adolescents 12-15 years of age, and for the additional booster dose in immunocompromised individuals.

The additional booster dose will be offered to those who meet immune suppressed criteria, beginning Aug. 25, at all Chickasaw Nation Department of Health (CNDH) clinic locations. The additional dose can be scheduled at starting Aug. 25.

In response to the increased presence of COVID-19 in our local communities, the Chickasaw Nation Department of Health (CNDH) has moved all testing and vaccinations to the Emergency Operations Facility (EOF), located at 1300 Cradduck Road, Ada.

Hours of operation have been extended to increase availability to Chickasaw citizens and the community. Drive-thru testing is offered at the EOF from 7 a.m. to 4 p.m., and vaccinations are available from 9 a.m. to 4 p.m.

Hours of operations at other CNDH satellite clinics in Ardmore, Purcell and Tishomingo are extended to 9 a.m. to 4 p.m. Drive-thru locations are identified on the scheduling website. All locations are open Monday-Friday.

The COVID-19 vaccine is available to the public at no cost at sites in Ada, Ardmore, Tishomingo and Purcell. To schedule an appointment, visit
