Rotary International has produced two videos on the fight against Polio. Permanent links to the videos are in the right-hand side panel and quick access to the link below this story
The videos show the history behind the fight against polio from the start in the late 70s through to how the world Health Organisation joined in and then the Bill Gates Foundation came in with the 2 for 1 dollar fund matching. The fight is still ongoing. 
Recommended viewing for all Rotarians. RI has recommended the videos are shown to the public on all possible occasions.
