As North Carolina opens vaccination appointments for all adults Wednesday, some local providers are adjusting by providing first doses without appointments. Novant Health Inc. said Tuesday it will offer walk-in options at two community events set for the Anderson Center, 1545 Reynolds Park Road on the Winston-Salem State University campus. Some of the doses come from the Federal Emergency Management Agency vaccination site at Greensboro's Four Seasons Town Center. About 600 doses will be given at each event. The first clinic is set for 8 a.m. to 4 p.m. Wednesday with the walk-in slots available between 10 a.m. and 2 p.m. The second clinic is set for 9 a.m. to 2 p.m. Saturday with walk-in slots available between 10 a.m. and 1 p.m.
