Albert Sabin

Albert Bruce Sabin (August 26, 1906 – March 3, 1993) was a Polish-American medical researcher, best known for developing the oral polio vaccine, which has played a key role in nearly eradicating the disease. In 1969–72, he served as the president of the Weizmann Institute of Science in Israel.

Biography
Abram Saperstejn (later Albert Sabin) was born in Białystok, Russian Empire (before and since 1918 in Poland), to Polish-Jewish parents, Jacob Saperstejn and Tillie Krugman. In 1921, he emigrated with his family on the SS Lapland which sailed from Antwerp, Belgium, to the Port of New York. In 1930, he became a naturalized citizen of the United States and changed his name to Sabin, as well as assuming the middle name Bruce. He graduated from high school in Paterson, New Jersey.

Sabin began university in a dentistry program, but was interested in virology and changed majors. He received a bachelor's degree in science in 1928 and a medical degree in 1931 from New York University.

In 1983, Sabin developed calcification of the cervical spine, which caused paralysis and intense pain. Sabin revealed in a television interview that the experience had made him decide to spend the rest of his life working on alleviating pain. This condition was successfully treated by surgery conducted at Johns Hopkins Hospital in 1992 when Sabin was 86. A year later, Sabin died in Washington, D.C., from heart failure.

Medical career
Sabin trained in internal medicine, pathology, and surgery at Bellevue Hospital in New York City from 1931 to 1933. In 1934, he conducted research at The Lister Institute for Preventive Medicine in England, then joined the Rockefeller Institute for Medical Research (now Rockefeller University). During this time, he developed an intense interest in research, especially in the area of infectious diseases.

In 1939, he moved to Cincinnati Children's Hospital in Cincinnati, Ohio. During World War II, he was a lieutenant colonel in the U.S. Army Medical Corps and helped develop a vaccine against Japanese encephalitis. Maintaining his association with Children's Hospital, by 1946, he had also become the head of Pediatric Research at the University of Cincinnati. At Cincinnati's Children's Hospital, Sabin supervised the fellowship of Robert M. Chanock, whom he called his "star scientific son".

Sabin went on a fact-finding trip to Cuba in 1967 to discuss with Cuban officials the possibility of establishing a collaborative relationship between the United States and Cuba through their respective national academies of sciences, in spite of the fact that the two countries did not have formal diplomatic ties.

In 1969–72, he lived in Israel, serving as president of Weizmann Institute of Science in Rehovot. After his return to the United States, he worked (1974–82) as a research professor at the Medical University of South Carolina. He later moved to the Washington, D.C., area, where he was a resident scholar at the John E. Fogarty International Center on the NIH campus in Bethesda, Maryland.

Polio research
With the menace of polio growing, Sabin and other researchers, most notably Jonas Salk in Pittsburgh and Hilary Koprowski and H. R. Cox in New York City and Philadelphia, sought a vaccine to prevent or mitigate the illness. This was complicated because there were multiple strains of the disease. In 1951, the National Foundation for Infantile Paralysis's typing program confirmed the existence of three main serotypes of poliovirus, since known as type 1, type 2, and type 3.

Salk developed an inactivated poliovirus vaccine (IPV), a "dead" vaccine given by injection, which was released for use in 1955. It was effective in preventing most of the complications of polio, but did not prevent the initial intestinal infection.

By carrying out autopsies of polio victims, Sabin was able to demonstrate that the poliovirus multiplied and attacked the intestines before it moved to the central nervous system. This also suggested that polio virus could be grown in other tissues besides embryonic brain tissue, leading to easier and cheaper methods of vaccine development. John Enders, Thomas Huckle Weller, and Frederick Robbins would successfully grow poliovirus in laboratory cultures of non-nerve tissue in 1949, an achievement that earned them the 1954 Nobel Prize in Physiology or Medicine.

Sabin developed an oral vaccine based on mutant strains of polio virus that seemed to stimulate antibody production but not to cause paralysis. Recipients of his live attenuated oral vaccine included himself, family, and colleagues. Sabin's first clinical trials were carried out at the Chillicothe Ohio Reformatory in late 1954. From 1956–1960, he worked with Russian colleagues to perfect the oral vaccine and prove its extraordinary effectiveness and safety. The Sabin vaccine worked in the intestines to block the poliovirus from entering the bloodstream.

Between 1955 and 1961, the oral vaccine was tested on at least 100 million people in the USSR, parts of Eastern Europe, Singapore, Mexico, and the Netherlands. The first industrial production and mass use of oral poliovirus vaccine (OPV) from Sabin strains was organized by Soviet scientist Mikhail Chumakov. This provided the critical impetus for allowing large-scale clinical trials of OPV in the United States in April 1960 on 180,000 Cincinnati school children. The mass immunization techniques that Sabin pioneered with his associates effectively eradicated polio in Cincinnati. Against considerable opposition from the March of Dimes Foundation, which supported use of Salk's relatively effective killed vaccine, Sabin prevailed on the Public Health Service (PHS) to license his three strains of vaccine. While the PHS stalled, the USSR sent millions of doses of the oral vaccine to places with polio epidemics, such as Japan.

Sabin's first oral poliovirus vaccine (OPV), for use against type 1 polioviruses, was licensed in the United States in 1961. His vaccines for type 2 and type 3 polioviruses were licensed in 1962.

At first, the monovalent poliovirus vaccines were administered together by being put on a sugar cube, because the oral polio vaccine had a bitter, salty taste (inspiring Robert B. Sherman's lyrics to A Spoonful of Sugar (Helps the Medicine Go Down) for the 1964 film Mary Poppins). In 1964, a single trivalent OPV containing all three viral serotypes was approved. Sabin's oral vaccine was easier to give than the earlier vaccine developed by Salk in 1954, and its effects lasted longer. The Sabin vaccine became the predominant method of vaccination against polio in the United States for the next three decades. It broke the chain of transmission of the virus and allowed for the possibility that polio might one day be eradicated.

Sabin also developed vaccines against other viral diseases, including encephalitis and dengue. In addition, he investigated possible links between viruses and some forms of cancer.

Philanthropy
Sabin refused to patent his vaccine, waiving commercial exploitation by pharmaceutical industries, so that the low price would guarantee a more extensive spread of the treatment. From the development of his vaccine Sabin did not gain a penny, and continued to live on his salary as a professor. The Sabin Vaccine Institute was founded in 1993 to continue the work of developing and promoting vaccines. To commemorate Sabin's pioneering work, the institute annually awards the Albert B. Sabin Gold Medal in recognition of work in the field of vaccinology or a complementary field.
