With winter on its way, another flu season is just around the corner. The flu shot is the best way to protect yourself and your family from getting the flu. For the more vulnerable, the flu vaccine is especially important. Public Health will be offering a free walk-in flu immunization clinic on Wednesday, October 24 from 3:00 - 7:00 p.m. at the Grey Bruce Health Unit, 101 17th Street East, Owen Sound.
