Disease are not infectious- on Vaccine- McBean

"During one of our most widespread polio epidemics (1949) contraction of polio by definite contact with other victims of the disease was not established in an elaborate study made by the New York State Health Department. The United States Public Health Service in its studies also found the same negative answer during succeeding outbreaks of polio. In short, they learned that the disease was not contagious.

TIME Magazine commented on this unexpected revelation of these surveys by remarking that "when and where people catch polio remains a mystery."

The supposition that viruses entered through the mouth and nose led the experimenters to make exhaustive tests on both animals and human beings, mostly prisoners and orphans in institutions. They were exposed (by close association) to polio patients and their throats and nasal passages were frequently swabbed with matter (from the patients) that was supposed to contain viruses. No polio was produced in this way and about the only noticeable after effect was that the subjects of the experiments lost their sense of taste and smell due to the damaging effects of the poisons in the serum that was used on the swabs."
