Of course, most have. But the sad reality today is that those in the risk groups, are vastly overrepresented in the ICU units. Here in Norway, the stats were something like the following:

Around half of those admitted were unvaccinated people in their 50s, the other half vaccinated and in their 80s. The former group was something like 5-7 times more represented. I think 90% of them were overweight or obese.

So, yeah, seems like if you get admitted to the ICU today, you're either a fully vaccinated very old senior citizen, or unvaccinated high-risk individual in your 50s.
