Question
In 1921, about ten years before he was elected president of the United States, Franklin D. Roosevelt became sick while vacationing in Canada. He had a fever, chills, and muscle pains, and he eventually lost use of his legs. He had contracted polio.
Polio is an illness that can damage nerves, weaken muscles, limbs, and even cause death. It primarily affects children and became widespread in the 1940s, twenty years after President Roosevelt’s diagnosis. Parents were frightened, as it was initially unclear how polio spread.
A scientist named Jonas Salk decided to fight polio by developing a vaccine to prevent it. After years of research, Salk was so sure his shot would work that he tried it on himself and his family. None of them got polio! Salk and his team then tested the vaccine on more people in 1954, and they found that it effectively protected against polio. By 1955, millions of kids received the shot. Now, it's rare to contract polio in the U.S. The even hopes to eliminate polio around the world this century.
