this is certainly a possibility and one not mutually exclusive to negative VE.

broad immuno-suppression and enhanced vulnerability becomes a tricky thing to spot except in full all cause deaths data. some will look like covid, some like sepsis, some like heart issues, etc, etc.

and that plurality makes tracking very difficult.

it's why we desperately need to be able to see all cause deaths data from d1, d2, d3 to comp to the unvaccinated and gauge risk reward.

the fact that it's not being tracked or made available is criminal.
