ANNAPOLIS, MD (AP) – Maryland residents can now get vaccinated without an appointment at any of the state’s 13 mass vaccination sites. Gov. Larry Hogan says walk-ups at various mass vaccination sites have been a successful tool in boosting the number of inoculated people in the state. Nearly 2.2 million people have been fully vaccinated in Maryland. The CDC says 62.5% of Marylanders 18 and older and 85% of residents 65 and older have received at least one dose of COVID-19 vaccine.
