“We are in a new phase of our vaccination effort where we are focused on making sure that no arm is left behind,” said Governor Hogan. “Walk-ups have been an incredibly successful tool, and we are now able to make them available at all of our mass vaccination sites across the state. The sooner we get more Marylanders vaccinated, the sooner we can put this pandemic behind us once and for all.”
