The correct answer is Jonas Salk, as he developed the first polio vaccine in 1952.

Two types of polio vaccine are used. The first was developed by Jonas Salk, first tested in 1952 and released on April 12, 1955. The Salk vaccine against poliomyelitis consists of an injected dose of inactivated or killed poliovirus (IPV). The second vaccine was an oral vaccine developed by Albert Sabin using attenuated poliovirus (OPV). Clinical trials of the Sabin vaccine started in 1957 and was authorized in 1962.

Through the use of the two vaccines, polio eradication has been achieved in most of the world and the incidence of 350,000 cases estimated in 1988 has been reduced to 37 cases reported in 2016.
