In areas with high vaccination rates....of course the case load is vaccinated people. They are virtually the only ones there.No, actually the liberal politicians and the liberal media is saying it is a "pandemic of the unvaccinated" but the medical community actually issued a warning to those voices. There are plenty of media voices that are telling the truth and showing that in some regions with high vaccination rates the case load is made up of vaccinated.
However, all that bias noted, the hospitalizations tend to be mostly the unvaccinated by a large majority.
Omicron may change things up even more. It is barely here in the USA now, we still have a vast majority of Delta. Omicron will likely become a wave in January.
Theoretically, with a population of 1,000 people and 90% vaccination, the infection rate of unvaccinated (100 total) could be 50%, and there would only be 50 infected. However, of the 900 vaccinated, the infection rate could be 6% and there would be 54 people infected...more than the unvaccinated.
At a 70% vaccination rate, if the infection rate of the 300 unvaccinated were 20%, 60 people would be infected. However, of the 700 vaccinated, if the infection rate were 9%, then there would still be more vaccinated people who got it than unvaccinated. This would have a tendency to show the vaccination was effective in some measure because the infection rate was much lower even though the total number of people was higher.
Therefore, saying that more vaccinated people are infected than unvaccinated doesn't tell us anything about the effectiveness of vaccination without knowing the vaccination rates, at least...and to be really accurate, a lot more demographic information about those who were infected. I don't know what the real numbers are and don't make any conclusions, but I am simply pointing out that "more people who are vaccinated got it" doesn't tell us anything in and of itself.
As more information rolls in, we will learn more.
Of course, the tougher thing to calculate is severity of an infection across people with the same health at baseline, vaccinated versus not.
