Actually there is surmountable evidence that clean drinking water, more sanitary conditions, underground plumbing, safer food handling and good old fashioned hand washing significantly contributed to the downfall and spread of polio long before the vaccine was ever given to the masses. And polio was NEVER eradicated. It has simply been renamed several different things. Transverse myelitis, acute flaccid myelitis, Guillain-Barre Syndrome. Perhaps you should read the hundreds of studies and dozens of books written on this very subject.
