Polio, WTF! Who has ever got polio in the past 50 years??? Did anyone ever get it in Australia?
...
The reason people don't get polio is because we are all vaccinated against it.
Did you think it disappeared by magic?
Vaccination reduces the viral load in the community so there is less of it to go round, and we all have immunity from the vaccination. It's simple, less virus and a less hospitable environment for it.
If people stop getting vaccinated then the diseases will come back.
This is the most insane issue ever. There are people dying in Africa because they can't afford vaccination (aside from clean water, hygeine and nutrition).
We get it as a matter of course, and we are healthier than any generation of humans in history, and people want to stop it because they're afraid of needles.
BTW Australian legend, Sister Kenny (
en.wikipedia.org/wiki/Elizabeth_Kenny ) developed a treatment for polio, which was a scourge in the early part of the 20th century. Kids used to get put into wheelchairs, or iron lungs, and left to rot for the rest of their lives. She worked out simple physiotherapy exercises that got them moving again. Hollywood made a movie about her.
