Isn’t this statistic in itself a little misleading though? Given that so many people are vaccinated now, the proportion of hospitalizations would be expected to trend higher in that group as the pool of unvaccinated people is shrinking at the same time.

Also, the eldest people (largely those most at risk of hospitalisation) are substantially more likely to have been vaccinated already, no?

In the context of the claim that, once vaccinated, you are in "no risk at all" for symptomatic COVID19, I don't think it's misleading: significant numbers of fully vaccinated individuals can and do become sick with the disease. Ergo, even when fully vaccinated, you still face some risk.

None of this is an argument against vaccination, of course.
