I had h2n3 during the 2012-2013 fu season. That’s the sickest I’ve ever been. I get the flu shot early but does that mean I have some natural immunity?

In brief: Could be true.

You may have some level of immunity against the H2N3 variant based on your illness with that variant back in the 2012-2013 season.
There’s a bit of cross-immunity which may provide you a bit of immunity against similar strains, too. But it’s always good to get vaccinated anyway to really be safe.

In brief: Not immune

each year has a different strain of influenza.
2012/13 likely has no connection to this year's flu.
