Albert Sabin is well known as the developer of the oral polio vaccine.
In 1961, Sabin’s live, attenuated polio vaccine replaced Jonas Salk’s inactivated polio vaccine that had been in use since 1955.
Although OPV is very effective and safe, because of the very small risk of vaccine-associated paralytic polio (VAPP), many polio-free, industrialized countries eventually switch back to IPV.
The United States switched back to IPV in 2000.
