My guess is it takes a while to do this sort of study. UK biobank was unusual in having such a large database of scans. Vaccination should reduce the risks. But there was a nurses study that 19% of the breakthrough cases had lasting effects. So I would not expect vaccination to eliminate the risk if a breakthrough happens.
