Does that mean 75% of people that are hospitalised specifically due to effects of Coronavirus were unvaccinated? Or does it mean that 75% of people that were hospitalised for any cause, and that then subsequently tested positive, were found to be unvaccinated? There's a big difference between the two. It would still be interesting if it were the latter, as that might indicate vaccination was somehow protecting the vaccinated against hospitalisation for causes that weren't immediately identifiable as being related to Coronavirus. I mean, it could be the case that the unvaccinated were suffering cognitive effects of infection that made them more likely to be in car crashes, for example.
