Is it all of Canada or just that one Ontario set of data?
If we're going to push the "Hospitalization with COVID" instead it's all "Hospitalization for COVID", it's possible that's the reason the Ontario graph looks that way.
Are there any other locations reporting similar scenarios where it's higher for vaccinated than unvaccinated people?
The NY Times newsletter today looks at NY City and Seattle for cases, hospitalizations, deaths between vaccinated and unvaccinated. They match the rest of the reports that unvaccinated is way way worse. They include some notes about the "with" vs "for", which really just makes the differences even larger.
I think that link should load the newsletter.
They call out some notes that while Omicron is milder (less hospitalization), that's way more true for vaccinated. For the unvaccinated it's still plenty severe to be an issue.
I would still love to know why the Ontario graphs look the way they do, as they definitely seem to be an outlier. Which makes me think there's a hidden story in there somewhere.
