Albert Sabin founded the oral polio vaccine and the vaccine was licensed in 1962.
the polio vaccine
In 1947, the polio vaccine was not yet available for public use; the first effective polio vaccine, developed by Jonas Salk, was introduced in 1955. However, there were experimental vaccines being tested before then. There were concerns about vaccine contamination in later years, notably in the 1950s, when some batches of the Salk vaccine were found to be contaminated with live poliovirus, leading to cases of vaccine-derived poliovirus infections.
Dr. Jonas Salk
In the 1950s, Salk developed the first polio vaccine, an injection. In 1962, Sabin developed the oral polio vaccine, taken by mouth, and still used, at present.
Jonas Salk's initial testing of polio vaccine is 60 - 70% effective against PV1 (poliovirus type 1, over 90% effective against PV2 and PV3, and 94% effective against the development of bulbar polio.

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. == == == == == == == ==
a vaccine that stops you getting polio!
Albert Sabin is best known for his development of a polio vaccine that used live, attenuated polio virus and was therefore more effective than the Salk vaccine.
