Mikhail Petrovich Chumakov (14 November 1909 – 11 June 1993) was a Soviet microbiologist and virologist most famous for conducting pivotal large-scale clinical trials that led to licensure of Oral Polio Vaccine
Polio vaccine
Two polio vaccines are used throughout the world to combat poliomyelitis . The first was developed by Jonas Salk and first tested in 1952. Announced to the world by Salk on April 12, 1955, it consists of an injected dose of inactivated poliovirus. An oral vaccine was developed by Albert Sabin...

Chumakov graduated in 1931 from Moscow State University

 Medical School that was later transformed into I.M. Sechenov Moscow Medical Academy. In 1937 Chumakov participated in a scientific expedition to Khabarovsk region of Soviet Far East that was led by Professor Lev A. Zilber. Together with his colleagues he discovered the etiology of a new transmissible neurological disease called tick-borne encephalitis (TBE) and isolated the virus that causes it. He was accidentally infected with the virus and developed encephalitis that led to a permanent loss of hearing and paralysis of the right arm. For this discovery he was awarded Stalin Prize of First Degree in Science and Technology in 1941. In 1948 Chumakov became a corresponding member, and in 1960 a full member of Academy of Medical Sciences of the USSR. Beginning in the 1940s Chumakov organized multiple medical expeditions to Siberia and other regions of the Soviet Union to investigate outbreaks caused by new viruses. Among viruses discovered and studied by Chumakov are Omsk hemorrhagic fever

. In 1958-1959 he organized the first mass production and clinical trials of Oral Poliovirus Vaccine (OPV) made from live attenuated strains developed by Albert Sabin. This made the Soviet Union the first country to develop, produce, license, and widely use this highly effective vaccine that practically eliminated poliomyelitis from the country in the first few years of its use. The vaccine produced by Chumakov's Institute was exported into more than 60 countries, and was instrumental in stopping large outbreaks of poliomyelitis in Eastern Europe and Japan. The success of the Russian clinical trials was critical to OPV licensure in the United States in 1962, and the vaccine becoming the main tool used in global poliomyelitis eradication

Chumakov held a Honoris Causa degree from Academia Leopoldina in Germany and was an Honorary member of the Hungarian Academy of Sciences. He also was an honorary member of Medical Societies and Academies of several other countries. After Chumakov’s death, the Institute that he founded was renamed in his honor as M.P.Chumakov Institute of Poliomyelitis and Viral Encephalitides of the Russian Academy of Medical Sciences.
