Certainly makes sense given what we're seeing, and if both covid and its attendant gene therapy shots damage people's immune systems, it's really rather a terrifying possibility. I haven't seen any research in this direction, that covid damages the immune system in general (rather than that specific IgG4 response to the covid pathogen), which is partly why I posted this. I think your theory does explain what we're actually seeing, but I'd like to see some research around that...

I guess all we can do about such a situation is to do whatever we can to help our own immune systems fight off the ever-increasing waves of pathogens. I have read that a few different mushrooms are good here, probably most researched being turkey tails (trametes versicolor), such that it's even part of some cancer therapies in Asia, intended to support people whose immune systems have been damaged by chemotherapy. Reishi is supposed to be good here, too. claire-58 has some good posts on this topic, too:

May the gods help us if this immune system damage theory is what is really going on. I'd imagine these waves of sickness would look more exponential than linear, and trying to imagine how that future is going to look...
