There's a lot of talk of antibodies because researchers studying vaccine effectiveness prior to everyone being exposed need something to measure.
It's hard to measure the overall effectiveness of a person's immune response, so they measure antibodies, which are not the whole story. It might not even be the important part. I think this is why GP is derisive of serology.
The immune system is quite complicated.
Personally I suspect that advising people who had breakthrough infections to keep getting boosters will turn out to be bad advice. We'll see I guess.
