I believe the data actually says that out of people who have Covid, vaccinated people are more likely to have the omicron variant than unvaccinated people who are also positive.For Omicron, by far more vaxxed people are catching it. And it is worse with a booster. Now for some reason this is happening (Antigenic Imprinting or ADE for example). The vaxx was designed for the Wuhan variant and now we have Alpha, Beta, and Delta - and now a completely new virus which is radically different.
This is why both Pfizer and Moderna says that the vaccine does not work against Omicron.
Now imagine that Omicron turned out to be severe disease with the vaxxed preferentially catching it. What would the world be like today with massive issues for the vaxxed population?
We could still have a future variant that could become severe disease. So we need to have much more focus on therapeutics as treatments. When are the Medical Bureaucrats going to realize that trying to defeat these virus requires much more than the singular sledgehammer of a vaccine created for the Wuhan variant.
That means that unvaccinated people with Covid are more likely to have a more serious variant. It may mean the vaccines are less effective against omicron, but if you are going to get it at least you get a less impactful version.
