How did the public’s perception towards vaccination during the polio epidemic differ from now? Why?

A current misconception is the belief that the polio is a 'disappeared disease'

Explanation:

Poliomyelitis (polio) is an infectious disease produced by a poliovirus. The polio is known to affect children under 5 years old and this infection can be spread among persons by fecal and oral routes.  Many people in developed countries erroneously believe that polio is a globally eradicated disease, thereby it is not necessary to apply the vaccine in children. However, poliomyelitis is not eradicated in the world, thus being imperative to vaccinate the children in order to prevent the introduction (and consequent re-infection) of this disease in developed countries.

i think it's the first one because doctors aren't the ones who get rid of the old needles. most of them time it's not even doctors who give you shots, it's nurses.

so what is your question?
