BA.4 & .5 are also being reported as to being able to escape antibodies.
Now, there's limited study on the above, but, to me, it would make sense to have some degree of preparation. Unlike the lead up to March 2020

This all depends on how vaccines are designed. If they are too specific they are great against the one they are designed for and may work on other variants if the target is still present.
I would guess that a real infection would prime the body to multiple targets on the virus and there would need to be a more major mutation to deny any immune response.
So as we progress getting reinfected we get to recognise various targets and target patterns.
Herd immunity doesn't mean individuals don't get covid or don't get seriously ill or even die. It means the herd survives.
