Programing your body to produce spiked proteins that your immune system has to constantly fight isn't safe, it's inflammatory. Arterial inflammation softens plaque which leads to clots. Nobody is being screened before given the shot. The mRNA shots aren't a weeks long process like the virus, it's months/years to keep spike proteins in your system. Your immune system will never recognize the virus with mRNA vaccines, just the proteins for short durations.

Basically you're over taxing your immune system, softening plaque, and diverting it from fighting other things. Such as the flu, colds, and cancer. So enjoy your super bugs while you're getting chemo.
