How do you know vaccines are keeping him out of the hospital? That's a talking point. He's also taking Paxovid. He's also pretty thin and healthy. My fat dad, prediabetic, two heart attacks, pacemaker, 76YO had a mild flu/bad cold for 3-4 days and was fine (this was before vaccines were avail, so it was an earlier variant). The current variants running around are mild, most people are fine regardless of vax status. And proving a negative is a fallacy, you can't say that something not happening proves your point.
And this is no longer a pandemic of the unvaccinated. It's getting really close to not making much of a difference. Do the vaccines wane quickly? Do they compromise immune response to Covid long-term? Looking at the data these are the questions we should be asking. I think it's possible that we're putting people on a never-ending vaccine schedule with a treatment that has a questionable safety profile. How much spike protein is too much?
Death rates are calculated as the number of deaths in each group, divided by the total number of people in this group. This is given per 100,000 people.

Just remember this chart the next time a three letter health agency tells you that you're 8X more likely to die without a vax - and keep in mind this isn't even an age-adjusted number (look at the younger population). The scale matters.
