A member asked:
Can you tell me if you've already had h1n1 and your immune system has naturally built up resistance to it, do you need a flu shot for it?
A doctor has provided 1 answer
Yes: Each flu shot is good for one flu season. H1N1 is covered with the current flu shot. 2014 – 2015 Flu Shots: Trivalent works against 3 influenza viruses – Influenza A viruses (H3N2 & H1N1) & 1 influenza B virus. Quadrivalent & the live attenuated Influenza vaccine work against these & a second influenza B virus.
