The mRNA vaccines tell your body to start producing cells with the spike protein encoded in them. Portions of the sequences closely resemble your bodies original DNA. Your immune system forms antibodies to these sequences and can confuse the sequences and start attacking the persons own body.

This is what usually happens when you have AIDS, your immune system attacks the body and organs. So this would make sense that they would want to make money off of the symptoms they created. It doesn't mean you actually have the HIV virus.
