This is interesting. PBS indicated that the vaccine is 30-40% protective against omicron infection and that it jumps above 70% with a booster. https://www.pbs.org/newshour/amp/health/how-effective-are-co... I wonder if the early data has been proven wrong or if something is wonky about Alberta. At even 30% effectiveness you’d expect to see a big gap between unvaccinated and vaccinated new cases. Weirdly near the bottom of your link they show nearly 90% effectiveness against all the variants of concern, but omicron isn’t listed. It seems like the vaccines would have to be negatively effective against omicron for all the other data to work out, though. |

It seems unlikely that the Alberta population is experiencing a significantly different pandemic than neighbouring regions (demographics and responses are largely the same). I also wouldn't conclude from this data that vaccines are negatively effective as hospitalization rates are lower in the vaccinated group.
