For my source, I googled polio eradication and found a link to the website – http://www.polioeradication.org/Polioandprevention.aspx

“Polio is a crippling and potentially fatal infectious disease. There is no cure, but there are safe and effective vaccines. The strategy to eradicate polio is therefore based on preventing infection by immunizing every child until transmission stops and the world is polio-free.”

The Global Polio Eradication Initiative’s website shows strong evidence that polio can in fact be eradicated through prevention and initiating vaccinations to countries that are still plagued by the disease. By making vaccines available to children in these countries and around the world would prevent polio from being passed from person to person until the disease would no longer exist.
