Since prions are defined as a misfolded or abnormal proteins, one could argue the mRNA instructions for the spike protein are in effect instructions to create prions. The manufacturers would argue that it's according to a plan so it's not misshapen, but it's certainly not natural for humans.
Didn't conspiracy theorists claim that the vaxx causes misfolded proteins too? Interesting.
Knowing that people are hard at work to make prions more deadly and more transmittable is even scarier.
