If you cruise around the internet, engaging with the anti-vaccine religion (not recommended), you will pick up on their standard tropes, lies, and other anti-science commentaries, like the claim that vaccines cause diabetes. Of course, once one digs into the scientific facts, you find little supporting evidence.
Moreover, Classen seems to come to his beliefs based on population-wide correlations that rely on post hoc fallacies, rather than actually showing causality between vaccines and diabetes. It’s like finding that a 5% increase in consumption of Big Macs is correlated with a full moon. Those two things may happen at the same time, but it would take a laughable stretch of real science to make a cause for causality.
Polio is a crippling and potentially deadly infectious disease caused by the poliovirus, a human enterovirus, that spreads from person to person invading the brain and spinal cord and causing paralysis. Because polio has no cure, the polio vaccine is the best way to protect yourself and the only way to stop the disease from spreading.
Predictably, the anti-vaccine community has decided to use this extremely rare virus to make specious claims about vaccines, pesticides, and who knows what else. Typical of these tropes, we pro-science types completely debunk it, thinking it’s dead and done. But like the metaphorical zombie, it arises again to eat the brains of anti-vaccine activists. So, here I go again.
