The first ever polio vaccine was developed by Dr Jonas Salk at the University of Pittsburgh in the early 1950s. It was a killed vaccine that was tested in clinical trials in 1954 and ultimately gained government approval by 1955 for use on the common public. There is also another polio vaccine that was developed by Dr Albert Sabin. This vaccine was a live version of the polio virus and is taken orally. It was approved for use in the general public in 1963. == == == == == == == ==
Two versions were independently invented.
I received both in early grade school.
In both the virus was grown then treated to eiter kill it (Salk) or make it weaker and slower to reproduce (Sabin). The Sabin was more effective but had a small risk of causing actual cases of polio, it can no longer be used in the US as this risk is now larger than that of catching wild polio here.

The Polio Vaccine.
Albert Sabin invented the oral live attenuated virus vaccine.
The polio vaccine is called the Salk vaccine after it was invented by Dr Jonas Salk.
Jonas Salk
Jonas Salk came up with the first injectable polio vaccine, followed by Albert Sabin who came up with the first oral polio vaccine.
The polio vaccine was made pubic in April, 1955.
Dr. Jonas Salk
Physician and researcher. He invented a polio vaccine.
Dr. Jonas Salk invented polio vaccine. He did not patented the vaccine. That made him the real hero. To day is his 100th birth day. (28th October 2014.)
Dr. Jonas Salk invented the vaccine against the polio. Before that the whole world was worried about the polio. Polio used to affect the most precious population, children! Two years before the invention of the polio vaccine, in US alone about 50,000 children got affected by polio. Dr. Jonas Salk did not get the patent for the vaccine, so that the vaccine became affordable for every body. Today is the 100th birth day of this hero. (28th October 2014.)Jonas Salk invented polio vaccine. He did not patent the vaccine, so that it should be made affordable to every body.
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.
