Flu season is here, with seasonal flu now reported as widespread across much of Tennessee. The Warren County Health Department is working to protect the entire community by providing free flu vaccinations to area residents until vaccine supplies are depleted. Appointments must be made to receive the flu vaccine and are now being scheduled at the clinic.“Vaccination is the best protection against the flu, and the Warren County Health Department and the Centers for Disease Control and Prevention recommend that everyone 6 months of age and older get a flu vaccine every year,” said Health Department director Michael Railing.
