>> So, let's try to understand this: if we throw a boatload of money onto this problem, is it possible to eradicate polio using that decent, more expensive vaccine? I think the answer might be - let's spend another boatload of money to develop an even better (oral) vaccine that can be distributed to those areas and not cause cases. It may seem a waste to create a new vaccine when the disease is almost gone, but so what? If Bill Gates can use his fortune to end Polio, I'll forgive him for unleashing Windows on the world ;-) OTOH if it makes a comeback that would mean all the money spent so far was for nothing.
