I agree that it would be useful if "natural immunity" were factored in - maybe in addition to vaccination per cent, another status called "immunity" should be added, totaling the vaccinated and the number of cases. This would be difficult if not impossible though, subtracting those who were vaccinated and had a breakthrough case, and those who had the disease and then were vaccinated. And now of course there will be another category added - "boosted." And then, are people who had the disease and then got vaccinated, or who had a breakthrough case, "boosted"?
But not really important to me any more. I just do the best I can to keep me and mine as safe as possible, while living a reasonable life, and let the chips fall where they may. If others want to fuck themselves or their community, so be it.
