Albert Sabin — developer of the oral polio vaccine

Early life and education

Born in what was then part of the Russian Empire to Polish-Jewish parents, Sabin emigrated to the United States as a child. He trained in medicine in the U.S. and established a career in clinical research and infectious disease, focusing particularly on viral infections that affected children.

Development of the oral vaccine

During mid-20th century efforts to prevent polio, Sabin advanced a vaccine made from weakened live poliovirus strains administered by mouth. Unlike earlier injected vaccines, his formulation stimulated intestinal immunity as well as bloodstream antibodies, which helped interrupt person-to-person transmission.

Impact and adoption

Large field trials conducted in several countries led to widespread adoption of Sabin's oral vaccine in national immunization campaigns. Because it was simple to deliver and effective at preventing spread, it became the vaccine of choice in many mass-immunization programs and greatly accelerated declines in paralytic polio.

Legacy, distinctions and notable facts

• Sabin received numerous awards and honors during his lifetime, including the Presidential Medal of Freedom.
• He chose not to patent his vaccine, preferring that it be made available affordably and widely.
• His name is commonly associated with oral polio vaccine efforts in global eradication campaigns.
