Similar figures from Denmark, reported as rates and broke down by age groups. Waiting for severe omicron cases stats, which may lag for a few weeks. We are in for an interesting winter...
I have a few theories of my own but it is not the point. And if you are curious, I still think everyone should get vaccinated / boosted, but I am just a random guy in the internet.
You ask if the figures take into account the fact that many people are vaccinated and the answer is yes. Draw your own conclusions. Even if you are convinced of the vaccine benefits (which I am), you shouldn't be in denial when the numbers don't match your expectations. If you do, then your reasoning is no better than that of conspiracy theorists, climate change denialists and antivaxxers.
Unboosted vaccine efficiency is negative for omicron, that's what the numbers are saying. If it contradicts your theory, then your theory is wrong and you have to find a better one. It you want to think scientifically, you have to consider the idea that vaccines can be ineffective/harmful, even if, like me, you don't believe it, because it is the most "obvious" conclusion. And only after you have accepted that possibility, you can look for confounding variables, mistakes and other effects that can disprove this idea.
