Prions is a subject all it's own.... This is a disease category that is really messed up. Because of the prion like nature of spike protein - our immune system doesn't know what to do with them - so they are encased in exomes and stored in places like the spleen - so they can and do travel to the brain stem and the brain later - where they enter normal cells and can turn on their protein miss folding engines - the normal cells then start to copy and miss fold normal cell proteins = horrible neurological diseases (mad cow, Alzheimers, Parkinsons, etc.) So the vaccinated who don't die can look forward to being zombies who will need shelter and care before their horrible deaths.
