Influenza spreads readily from person to person in schools, workplaces and homes. Everyone 6 months of age and older should get an annual flu vaccine to prevent sickness, healthcare visits, hospitalizations, and deaths from influenza.

Protection lasts throughout the flu season, which usually peaks in January or February and continues into the spring. Talk with your healthcare provider or pharmacist about which flu vaccine is recommended for you.
