Vaccine Booster Shots Available through DELCO

Delaware County Public Information Office

Starting Thursday, September 22, the Delaware County Health Department (DCHD) will begin providing the bivalent formulation of the Pfizer-BioNTech COVID-19 vaccine booster to Delaware County residents (the Moderna bivalent formulation COVID-19 vaccine booster is not yet available at DCHD vaccine clinics).

The new bivalent boosters—developed specifically to combat Omicron subvariants BA.4 and BA.5—were approved for use by the FDA on August 31 and give individuals broad protection against COVID-19.

The Pfizer-BioNTech formulation of the bivalent COVID-19 vaccine booster is approved for use for individuals 12 years of age and older. Adolescents must be accompanied by a parent or caregiver in order to receive a booster shot. 

DCHD will make the Pfizer formulation available to residents at its Thursday, September 22 vaccination clinic at the Delaware County Wellness Center at Yeadon, followed by its Monday, September 26 vaccination clinic at the Delaware County Wellness Center at Chester, and at the 69th Street Terminal in Upper Darby on Wednesday, September 28. All vaccinations are free of charge.

Delaware County residents interested in receiving the booster through the Delaware County Health Department are urged to schedule an appointment, though walk-ins will be welcome as supplies last.
