Virology is pseudo science. Contagion is a myth. This is where the "verify" of "don't trust, verify" is available for anyone who is willing to develop sane lifestyle habits. You can be around "infected" people all day long without any fear of evil spirits entering your body from another person. If your kitchen is clean, you will not have roaches.

So the polio and measles vaccines are a hoax and people suffering from these diseases coincidentally declined at the same time as the vaccines were introduced?
At the same time, no, before.
1) What was the reason for an increase in measles cases a few years ago in unvaccinated populations in the US? Or was that all part of the conspiracy?
2) Every medical professional who has worked on viruses and vaccines since, what, the ‘60s or ‘70s has been deceived or wilfully lied about their efficacy?
