Itâs the sixth Tennessee county to reach that mark. According to data from the Tennessee Department of Health, more than 46% of Washington County residents are fully vaccinated, which is the fifth-highest rate among the stateâs 95 counties. As of July 21, Washington County has administered 123,542 doses of the vaccine, which is the ninth-most in the state, and second-most in Northeast Tennessee behind Sullivanâs 128,652 doses. In a statement to the Press, the Northeast Regional Health Office said the Washington County Health Department continues to offer vaccines on-site from 8:30 a.m. to 4 p.m. Monday to Friday, in addition to its nurse strike team that continues to hold off-site vaccination events and encourage vaccine uptake.
