Due to the an ongoing outbreak of hepatitis A, the Kentucky Department for Public Health is recommending vaccination for everyone residing in Jefferson, Bullitt, Hardin, Greenup, Carter, and Boyd counties. Over 300 cases associated with the outbreak have been reported. For adults, the hepatitis A vaccine is typically given in two doses, an initial vaccination followed by another shot six months later. While the current hepatitis A outbreak is occurring primarily within specific at-risk population, such as illicit drug used and homeless, through person-to-person transmission, it is recommended that children and adults in counties with local transmission of the virus receive the vaccine.
