Maine’s third large-scale coronavirus vaccine clinic is expected to be opened by mid-February in a shopping center in hard-hit York County.

Details are still being finalized, but the location will likely be the closed Marshalls store in Sanford, said Art Cleaves, the director of the York County Emergency Management Agency. It will be staffed by a combination of York Hospital and MaineHealth’s Southern Maine Health Care location in Biddeford. The clinic is expected to vaccinate older Mainers as the state works its way through the second part of its first vaccination phase, he said.

Maine Center for Disease Control Director Nirav Shah said on Tuesday the clinic could vaccinate up to 1,200 people a day, making it the third-largest clinic in the state. The Cross Insurance Center and Scarborough Downs, where Northern Light Health and MaineHealth, respectively, have created two clinics, are capable of vaccinating up to 2,000 people a day, though limited supply is keeping those clinics far under capacity as they ramp up.
