Influenza vaccination schedule: when is the influenza vaccine given annually?

Explanation:
Timing the influenza vaccine in the fall, usually October or November, best aligns immunity with the start of rising flu activity. It takes about two weeks after vaccination for antibodies to develop, so getting vaccinated in this window helps provide protection during the peak season. Flu strains also change each year, which is why an updated vaccine is given annually. Vaccinating in January or later can miss much of the season, and July or March is outside the typical flu period.
