Theory is that people could genetically get the spike protein into their DNA, and these people will get auto immune issues the next time they get sick with Covid, as the immune system will attack both the virus and its own body.

But this theory doesn't account for that their body isnt attacking itself right now even though it might have genetically expressed spike proteins in their body. And if they get infected in the future by a new variant, that new viral spike protein will look totally different due to mutations than the one created genetically by the body. So the body will not confuse the two.

The point is that the auto immune reaction happens mainly when getting the jab. Thats when people develop these clots and stuff.
