The oral Sabin vaccine protects against poliomyelitis. The live oral polio vaccine was developed by Albert Sabin and came into commercial use in 1961.

Two types of vaccine are used: an inactivated poliovirus given by injection (IPV) and a weakened poliovirus given by mouth (OPV). The two vaccines have eliminated polio from most of the world, and reduced the number of cases reported each year from an estimated 350,000 in 1988 to 33 in 2018.

Albert Bruce Sabin (August 26, 1906 – March 3, 1993) was a Polish-born American medical researcher best known for having developed an oral polio vaccine. He received many awards and honors including the Presidential Medal of Freedom.
