The Tokyo olympics were early August. This bell curve pattern is much more likely to be the result of a stimulus that peaked around late august. Assuming 2 week incubation period, the olympics would be just as much an explanation as anything else. Introduce a new source, population gets infected, and then immunity eventually builds. This graph almost certainly makes the case that vaccination has little effect or the rate of increase or decrease in "cases" given that there was almost certainly no spike in vaccinations. I'm also less concerned with cases than hospitalizations and deaths. Ivermectin should be an option to anyone considering the dismal results of the other options.
