Home/Why do I need a flu vaccination every year?

Flu viruses change from year to year, which means two things:

  1. You can get the flu more than once during your lifetime.
  2. A vaccine made to protect against flu viruses circulating last year may not protect against the newer viruses. That is why the influenza vaccine is updated to include current viruses every year.
