The Guilford County Department of Health and Human services is no longer offering walk-up COVID-19 vaccination appointments at two clinics. Starting this Friday, appointments will be required at the county’s Greensboro Public Health Clinic and High Point Public Health Clinic. In a press release, officials said the change was made to ensure patients “can remain safe and socially distanced inside the clinics.” Appointments can be made by phone or online. Forsyth and Watauga counties are both still taking walk-ins.
