The Sabin vaccine is an oral vaccine containing weakened forms of strains of polio viruses. In 1955, Salk's "killed" vaccine was released for use. It was effective in preventing most of the complications of polio, but did not prevent the initial intestinal infection. The Sabin vaccine is easier to give than the earlier vaccine developed by Salk in 1954, and its effects last longer. Sabin first tested his live attenuated oral vaccine at the Chillicothe Ohio Reformatory in late 1954. From 1956-1960, he worked with Russian colleagues to perfect the oral vaccine and prove its extraordinary effectiveness and safety. The Sabin vaccine worked in the intestines to block the poliovirus from entering the bloodstream. In the intestines, Sabin had discovered, the poliovirus multiplied and attacked. Thus, the oral vaccine broke the chain of transmission of the virus and allowed for the possibility that polio might one day be eradicated.

Polio vaccines are vaccines used to prevent poliomyelitis. Two types are used: an inactivated poliovirus given by injection and a weakened poliovirus given by mouth. The World Health Organization recommends all children be fully vaccinated against polio.

Helpful section. Thanks.

Wasn't the Polio vaccine descovered together by Sabin and Salk?

Also he did not create a patent (owning the rights of anything new) for his medicine and proved to be a good savior of mankind. (Real genius).

Jonas Edward Salk was an American medical researcher and virologist, best known for his discovery and development of the first polio vaccine. He was born in New York City to parents from Ashkenazi Jewish Russian immigrant families.

What is polio vaccine?
