As demand wanes, WellSpan Health offers walk-in COVID-19 vaccinations York Dispatch WellSpan is now accepting walk-ins for COVID-19 vaccinations, and a spokesperson says it is because there has been a decrease in the number of people seeking shots. As of Friday, anyone 16 years and older can get vaccinated the same day from noon to 3 p.m. on selected days and at selected locations, according to a WellSpan Health news release. WellSpan started seeing a decline in demand about two weeks ago, which could be attributed to existing barriers such as scheduling conflicts or vaccine hesitancy, spokesperson Ryan Coyle said. "We're seeing the same decline in requests for appointments that health systems are seeing around Pennsylvania and around the country," Coyle said. "We believe there's a great number of people that are hesitant."
