Visits include 5 to 8 p.m., Tuesday, Aug. 10, First Responder Night in Milford; 10 a.m. to 12 p.m., Thursday, Aug. 12, Laurel Senior Center, Laurel; and 1 to 3 p.m., Aug. 12, Save A Lot, Seaford. See a full list of community-based events statewide including those organized by vaccinating partners and community groups at
