Polio peaked in the U.S. in the year 1952, with 57,879 cases. Once the vaccine became widely available in 1955, this figure dropped to 29,000 cases. So, to claim that polio cases were dropping significantly before this point is incorrect.

the person asked where the down votes were coming from. I explained it.
as for your nonsense. rates are only informative when the denominated is included, without knowing what they’re relative too its essentially nonsense. for example: if its relative to the total population then its useless w/ respect to vaccines since not everyone within the population will contract the disease. Which any dataset dealing with sanitation and disease would be relative to the total population. Vaccines mortality rates are measured against the population that contracts the disease.
directly comparing the two is retarded. full stop no further discussion needed.
