I don't. The stuff I come across tends to be about an individual state or hospital, but it's pretty much always 90%+ in the hospital are unvaccinated, and sometimes it's closer to 100%
I think Israel recently reported that vaccine efficacy was down to like 17% in people who received it in January. Would be important to find out if is that an age thing or if it tends to wear off at a similar rate across age groups. The good news is that the vaccines are still holding up well against severe disease on a percentage basis. But if more vaccinated people are getting sick to begin with, the numbers with severe illness are going to rise even if the % efficacy against severe illness never went down.
