Invention
            Jonas Edward Salk spent a lot of his time researching and inventing the polio vaccine. Salk first began working on the polio vaccine in Pittsburgh using “killed” or inactive viruses. There was a genuine fear and skepticism about his killed-virus vaccine. “In 1949, as a research professor, Salk began a three-year project sponsored by the National Foundation for Infertile Paralysis (polio), an organization also known as the March of Dimes.” It took a series of three or four injections with the killed virus vaccine to complete the immunity process. “He conducted the first human trials on former polio patients and on himself and his family, ant then in 1954 Clinical trials began on some 1.8 million U.S. School children.” Salk figured out that a dead cell added to the body will serve as an agent that will get the body to produce antibodies that will attack the bad organisms. Salk had a rival named Sabin. Salk and Sabin both wanted credit and fame for who got the credit for making the polio vaccine. “Jonas Salk had dedicated his life to finding the cure for war—in his words, “Finding a cure for the cancer of the World.”
