Polio actually can not be cured. There is, however, a vaccination that can be taken to prevent people who do not have polio, from getting polio. The polio vaccination was created by Salk and Sabin. Originally, the polio vaccination by Salk was administered in the form of a shot. The Sabin is given by mouth.
Jonas Salk never cured polio. The killed virus vaccine that he developed was able to keep people from getting the disease, but it did nothing for those who already had polio.

There is still no cure for polio, a disease that has been known since ancient times. Polio did not become epidemic until the late 19th century, when improvements in community sanitation prevented widespread development of immunity to the virus in early childhood. In 1535, there was no treatment for the condition. People either lived with their crippled condition, or died.

A polio vaccine was invented in 1954. Each year after that, the number of polio cases decreased. By 1974, only 5 cases occurred. These were all people who were linked to the polio vaccine.
