At the Rotary Convention in Atlanta we were advised that it would cost $1.2 billion to continue giving polio vaccines for the 3 years after the last case  -which is required to be able to declare Polio Eradicated.
At Convention is was announced that Rotary would contribute $50 million a year for 3 years. Then Bill Gates committed $300 million in matching Rotary. Canada pledged $100 million, Pakistan $70 million, then Country by Country additional pledges were made - to bring a total of $1.2 million - to see the end of Polio.
It was very impressive to have Rotary organise such a huge commitment from so many.
