It’s technically still summer, but the Centers for Disease Control and Prevention (CDC) says it’s already time to think about flu season 2018-2019.
All adults and children older than six months should get a flu vaccine by the end of October 2018, the CDC says. (The American Academy of Pediatrics recently made a similar recommendation.) While the shot is still effective for those who get it later in the fall or winter, getting vaccinated before flu season is in full swing offers the best protection, the CDC says.
