It was perverse - it appeared in industrialized nations…

““It was perverse - it appeared in industrialized nations, but it left poor people alone. George Carlin even made a joke about it. He grew up poor. He and his friends “swam in the raw sewage” of the East River. “It gave us immune systems,” he said. “Unlike you rich pussies!” He was joking, but what if he was half right? What were the mothers of middle-class children doing that the poor weren't? It didn't act like a plague. It appeared in summer. Adults never got it from children. People didn't “pass” it. It came out of nowhere and exploded in clusters. Whole schools would be taken down by a flash of profound muscular weakness, leaving some paralyzed and killing a few. Industrial history had demonstrated that neurological and paralytic Illnesses tended to act just this way - to explode, violently, in clusters. But among academic scientists, there was no interest in toxins. The going concern in medicine was to nail down tiny particles. Pollution was not on the agenda. Instead, the focus went to something invisible that could perhaps be filtered from blood. Something never seen, but suspected to be there. These invisibles would be blamed for all illness. And vaccines would be invented to stop them. “Just as Pasteur and Jenner had done,””
