It was developed by Albert Sabin and first licensed for use in 1961. The vaccine provides lifelong immunity after multiple doses and has been instrumental in reducing global polio cases. Because it contains live viruses, there is a small risk that it can cause vaccine-derived poliovirus (VDPV) in rare cases. The Sabin vaccine has largely been replaced by the inactivated polio vaccine (IPV) in many countries due to safety concerns associated with VDPV.
