Wow! You have my sympathy and my admiration. You've survived a very tough disease and a very rough therapy. I hope your disease stays in remission.
I have to disagree, this is incorrect. (I just saw Mr._Clark saying something similar.) The vaccines actually do prevent infection by the virus.
Previously, those two large clinical trials from last fall vaccinated very large numbers of people, but after vaccination, they followed up by asking if people developed Covid-19 disease, with all it's various symptoms. The trials did not ask if people developed symptom-free infections. When the trials began, there was simply not enough polymerase chain reaction (PCR) testing available to test everyone on the trial. Only if someone became sick, and Covid-19 was suspected, were they tested by PCR to confirm the disease.
As a result, the trials could only conclude whether vaccination could prevent Covid-19 symptoms. In science and medicine, you can't make conclusions without data to support them. The popular press and the public, misinterpreted this. The vaccine does indeed prevent infections, but the early clinical trials could not prove that.
Since then, there have been more studies that did address the questions about symptom-free infections. The results clearly show that the vaccines do prevent virus infections. This includes Covid-19 disease (with or without hospitalization or death) as well as symptom-free infections.
In nature, nothing is 100%. There are always a few people who get infected even though they were vaccinated. But the odds of getting infected after vaccination are much lower than without vaccination.
Here's the data from that New England Journal of Medicine link that Mr._Clark provided. It clearly shows how highly effective the vaccines are. To compare these results with those of many earlier vaccines against viral diseases like polio or measles, the Pfizer and Moderna vaccines are out-of-the-park grand-slam home runs. I'll take those odds any day.
