Detailed explanation-1: -Trivalent oral poliovirus vaccine (tOPV) Developed in the 1950s by Albert Sabin, tOPV consists of a mixture of live, attenuated polioviruses of all three serotypes. Also called the ‘Sabin vaccine’, tOPV is inexpensive and effective, and offers long lasting protection to all three serotypes of poliovirus.
Detailed explanation-2: -The Sabin oral poliovirus vaccine, composed of live-attenuated strains of the three poliovirus serotypes (38), has been used to control and reduce greatly the incidence of poliomyelitis around the world during the last 30 years.
Detailed explanation-3: -Inactivated poliovirus vaccine (IPV) is the only polio vaccine that has been given in the United States since 2000. IPV protects against severe disease caused by poliovirus in almost everyone (99 out of 100) who has received all the recommended doses.
Detailed explanation-4: -Albert Bruce Sabin (1906–1993), the man who made the oral polio vaccine. A second type of polio vaccine, the oral polio vaccine (OPV) was developed by physician and microbiologist Albert Sabin. Sabin’s vaccine was live-attenuated (using the virus in weakened form) and could be given orally, as drops or on a sugar cube.
