Polio, a crippling disease that makes it difficult or impossible to walk, was eliminated in the United States after the introduction of a polio vaccine in the 1960s. Now, with the lead of Rotary International and the Gates Foundation, efforts are underway to eliminate polio in the world, just as smallpox was eliminated. There are still only six countries where polio has not yet been eliminated but is being fought vigorously.
