Since I don't see any data forthcoming and
Barbarian has given the answer, I'll elaborate just a little bit, as I have dealt with this several times on Facebook and I thought even here once or twice before.
There were articles that spread among news outlets late last year that as of August 2022, 58% of deaths from COVID were people who were vaccinated. Of course, a number of right wing outlets, such as the "ever reliable and trustworthy" FOX News, and individuals used this to try and prove the uselessness of vaccines. In this case, what has happened is what is known as the base rate fallacy. This can happen when people simply appeal to absolute numbers without considering the case rate, which is often per 100,000 when dealing with these large numbers.
That 58% of people who died from COVID were vaccinated tells us very little. All it tells us is that the number of vaccinated people dying from COVID was increasing. And there are reasons for that, such as variants that are better at evading immunity (both from vaccines and infection), immunity wanes (both from vaccines and infection), and the overall number of vaccinated people has increased.
At that time, according to the CDC, about 80% of the U.S. population were fully vaccinated or boosted, which means about 20% were unvaccinated. Applying just a little critical thinking, one can easily see that 41.7% of the deaths came from 20% of the (unvaccinated) population, which is much worse than 58.3% of the deaths from 80% of the (vaccinated) population. That alone tells you there is much more to it. You can even roughly estimate quite quickly and see the problem: 80/20=4 (4 times the population is vaxxed vs unvaxxed); 58.3/41.7=1.398 (how many more times the vaxxed died than unvaxxed). Therefore, 4/1.398=2.86. That is, the unvaxxed are around 2.86 times more likely to die.
The following is based on the numbers I ran, back in November, but I don't remember if the numbers were from August, September, or October. When we look at the numbers that actually matter, the death rate per 100,000, the data clearly shows that an unvaccinated person (5.35 deaths/100,000) was slightly more than twice as likely to die as someone who was vaccinated or boosted (2.65 deaths/100,000). But, even that is a bit tricky since that was only of those who get COVID. When we look at the numbers for people getting COVID in the first place, again, an unvaccinated person (1487.98 cases/100,000) was slightly more than twice as likely to get it than someone who was vaccinated (685.26 cases/100,000).
Putting those numbers together means that overall, an unvaccinated person was about 4.3 times more likely to die from COVID than a person who was vaccinated. And, remember, that is just one month. I checked my numbers at the time with what the CDC produced, and I was off by a very small margin, but that could easily be attributed to population estimates.
It is easy to see that the vaccines are still effective, the bivalent one even more so, and one is far better off to get vaccinated than not.
