Should you exercise after a flu shot?

There are certain situations where it would be appropriate to get a flu shot after having had the flu. See the group of related questions below for information on these circumstances and the reasons this may be needed. The risk of problems with the flu, especially for those in high risk groups, far outweighs the very minimal risk of getting a vaccination.

If you are 100% sure from lab testing that the flu you had is the same as the vaccination, then there would be no reason to get the shot. Since the seasonal flu shots contain vaccine for three different types of flu, then the odds that you already had all three is very low. It will not hurt you to get a flu shot for the type of flu you already had, so to be on the safe side, go ahead and get the vaccination.
