  > Do we have studies for this that compare two controlled groups in same environment? are you questioning the link between vaccines and polio almost entirely disappearing from all but about 4 countries on the planet? what alternative "theory" do you have in this case?

    Increasing wealth and overall hygiene. 99% polio cases are nowadays in developing countries.
