Have you already had the flu?

Even if you have already had the flu, you may need flu shots. Here is how to tell:

  • Remember that different flus come about from different strains of the flu virus. Flu viruses are varied, and with each variation, your body needs a different immunity to fight it. Flu shots provide that immunity, but you'll need a different shot for each variation.
  • If you had the seasonal flu prior to this current flu season (a flu season typically runs from Fall through winter, into the following early summer) then you may still catch the more current flu because seasonal flu strains change from year to year. .
