The latest omicron boosters are 84% effective at keeping seniors 65 and older from being hospitalized with Covid-19 compared with the unvaccinated** by **Wagamaga**

> I’m not against the shot. But here is the reality. The vaccine doesn’t prevent you from getting it nor does it prevent you from spreading it. Because of that, no matter how many shots are given to each person, there can not be herd immunity.

You need to learn some basic epidemiology. Herd immunity doesn't, nor has it ever relied on 100% effective vaccines (which have never existed). It requires the vaccine efficacy to reduce the effective R value below 1 so that the virus dies out and can't properly spread.

You're trying to apply static, reductionist and simplistic reasoning to a complex nonlinear dynamical system. That will never work. Nor is it a remotely reasonable thing to do.

> Only 24% of the hospitalizations in my area are unvaccinated. The other 75% are vaccinated. Over half of those are up to date on the vaccine. At that point, it’s up to the individual.

You're now trying to compare numbers which require calculus without the use of calculus. That's not how math or statistics works at all.

I suggest you try to learn the bare bones basics of epidemiology (including the necessary mathematical prerequisites) before trying to comment in the science subreddit about it.
