Not everyone gets to have a "perfect" God given immune system though. Plenty of people have autoimmune issues, I'm one of them with a couple autoimmune issues. It's not because of some poison out there in the world or big pharma, it's genetic. I'm not old and sick or anything, in my early 30s and have fought this stuff for about a decade by now. But just because you have a good and proper immune system that may be able to handle catching covid and get through it reasonably well doesn't mean everyone is that way.
