Chester County opens walk-in sites for COVID vaccine

Chester County Health Department officials announced a number of COVID-19 vaccine clinics now offer walk-in vaccinations.   County health officials encourage everyone who is eligible, but has not yet received the vaccine, to take advantage of this free, convenient option.

From Friday, May 7, the Health Department’s walk-in vaccine clinic at the Exton Square Mall (former Sears store) will offer Pfizer and Johnson & Johnson vaccines, and the Longwood Gardens overflow parking area drive-thru clinic will offer Moderna and Johnson & Johnson vaccines.  These clinics are open Tuesday through Sunday.

Three senior centers in the county now serve as walk-in clinics, administering the Moderna vaccine.  These senior centers are Phoenixville Senior Center, Oxford Area Senior Center, and Brandywine Valley Active Aging in Coatesville.

Appointments for the Pfizer vaccine continue to be booked for the Chester County Government Services Center in West Chester.

As of May 5, 2021, Chester County leads the region with 70 percent of eligible people partially or fully vaccinated.  Currently, 38% of all Chester County residents age 18 and over are fully vaccinated.

Chester County Health Department Director Jeanne Casner said, “Chester County’s lead in vaccination rates is great, but this final push is key.

“We encourage everyone eligible who hasn’t yet been vaccinated, to book an appointment or just walk in to a clinic, so that Chester County becomes one of the first counties, or even the very first county in Pennsylvania to meet – and exceed – the Governor’s benchmark of 70 percent fully vaccinated.  Let’s do our part now, to become mask-free.”
