Missed that! so essentially we're seeing the same "rate" for unvaccinated/vaccinated for 1/4 vs 12/20 "2x"
No, I was saying that both the ratio of the unvaxxed to vaxxed in the Quebec tweet and in your calc were similar.
You can argue they don't have full immunity yet
If the question is whether vaccinations in general decrease risk of hospitalization, it makes no sense to lump 1 dose in with unvaccinated. That group fared the best in the data (many possible reasons), so I understand why you wouldn't want to include it with 2 doses, but then leave it out - don't sneakily try to boost the unvaccinated group with the performance of the 1 dose group.
Now we need to adjust this by age since 65-70% hospitalized are 60+ with a 94% vax rate.
It really doesn't help much. I played around with the data (links to
vaccinations and
hospitalizations) a bit, and it seems like the ratio is even worse for 40-59 (ie unvaccinated is worse off relative to vaccinated in that category than 60+).
I didn't do the full workup for the 28 day period ending 2 weeks or a month ago. It's possible that Omicron is leveling the playing field somewhat - but it hasn't come close to eliminating the advantages of vaccines.
