Mecklenburg County âmeets people where they areâ to administer vaccine Vaccine supply vs demand issues By Paige Pauroso | May 7, 2021 at 9:33 PM EDT - Updated May 13 at 4:31 PM CHARLOTTE, N.C. (WBTV) - Mecklenburg County says supply of the vaccine is higher than ever, but demand is lagging. More than 50 percent of North Carolinians have at least one dose of the vaccine. But in Mecklenburg County, itâs only 30 percent, according to state data. Now the county is ramping up on a new approach. Theyâre brining the vaccine to the people. Weâve seen partnerships like this already where the country is bringing their clinics to social events on the weekends.
