In my state it is about 57%: https://portal.ct.gov/Office-of-the-Governor/News/Press-Rele...

A statistic like this is meaningless unless qualified and supported with a link to a reliable source. All hospitals in the US, UK, European countries, South America, world?

It's also meaningless unless compared to the population.

"90% of the people in this hospital for COVID today are unvaccinated" is a very different statement when, for hypothetical examples,

- 90% of the people in the local area area are unvaccinated: Hospital population is same as general population.

- 10% of the people in the local area area are unvaccinated: Hospital population is mostly drawn from the unvaccinated.

And points in-between, and the other way (what if - for sake of example only - 95% of local people are unvaccinated?).

And then there are further confounding effects - what if unvaccinated people are younger and than average, as vaccines are given preferentially to older people who are more likely to require a hospital visit in normal times.
