Yes polio is very easy to control and eradicate. Even antivaccinators have no argument of this being new vaccine and causing Sid effects . It’s been around for generation with near perfect record of safety.Polio is pretty easy to beat. Clean up the water and you are all set. Another virus in that genus rhinovirus on the other hand is the most common virus infecting humans. That's because rhinovirus is airborne.
It’s the lack of education and a particular class of morons that exist in every country that make it possible for the disease to survive .
Here in Canada we had wierd looking people protesting outside the hospitals harassing and blocking doctors and nurses. Government quickly passed a legislation approving arrests of any such idiot.
I firmly support that the world should get together and pass a universal law to castrate these morons and save us from having to deal with equally or even more stupid morons in the future.
