You seem to be confused. The statistics on how many people died from COVID and whether they were vaxed or not has nothing to do with unreported cases where people caught COVID and recovered.
“In other words, there are COUNTLESS cases of unvaccinated people who got covid, and were perfectly fine, but were never counted in the stats.”
Why would these people be counted in death statistics? You need to take a course in logic.
You would obviously have to know how many people did NOT die, in total, to determine an accurate percentage representation of how many people DID die. This would be for both the vaxxed, and un-vaxxed sets. I see stats is not your strong suit.
