Should I get a flu shot if I already had the flu this season?

Infectious Diseases Vaccines

A: Yes. The flu shot covers FOUR strains – you don’t want to catch it again!

TL;DR: It’s hard to know which flu strain you got or which one will be dominant in the next few months. Go ahead and get that shot even if you had confirmed or suspected influenza.

The current flu vaccine is “quadrivalent” meaning it protects against four different flu viruses–two influenza A viruses and two influenza B viruses.

So far this season over 67% of specimens tested by public health laboratories have been one of the two strains of Influenza A, and 33% Influenza B. While a recent infection should give you near term immunity against the specific strain you had, you still have a chance of getting a different strain.

If you’ve been laid low by the flu recently you KNOW you don’t want to go through that again. Go ahead and get that shot! It’s safe to do so once you fully recovered from your illness.
