Why the annual flu shot then? All the various strains/mutations?

I would get the vaccine, even if I had COVID prior because, at worst, it will act as a booster for your immune system that could be waning. There is a possibility that the vaccine could be more effective than an asymptomatic or mildly symptomatic person. I'm not sure.
Yes, we need an annual flu shot because Flu A mutates quickly and tends to be more deadly like the H1N1 variants known for several pandemics. Flu B mutates slowly, and most people have some type of childhood immunity, so they will only get Flu B a few times in their life at most. Scientists go around the world and look at mutating flu variants in birds (avian), pigs (swine) and other local animals that could cross over to humans.
