An American physician and bacteriologist, Zinsser isolated the bacterium that causes typhus and developed a protective vaccine against it. In 1935 he published the book 'Rats, Live and History' in which he recounted the effects of typhus on mankind and the efforts to eradicate it. In the book he argued that disease was responsible for more deaths than war.1940-09-04T00:00:00+0000The breakthrough was made by Hubert Loring and Carlton Schwerdt. They managed to isolate the virus with 80% purity. The work paved the way for the team to create the first vaccine in August 1947. Schwerdt continued to improve the technique and by 1953 had managed to isolate 100% pure polio virus with Bachrach Howard, which paved the way for Jonas Salk to create a safe vaccine in 1955. 1947-01-10T00:00:00+0000The work was carried out by John Enders, Thomas Huckle Weller ad Frederick Chapman Robbins. They published their achievement in TH Weller, FC Robbins, JH Enders, 'Cultivation of poliomyelitis virus in cultures of human foreskin and embryonic tissues', Science, 109/2822 (1949), 85-7. The work paved the way for the two kinds of effective poliovirus vaccine, the inactivated poliovirus vaccine of Jonas E. Salk and the live oral polio vaccine of Albert B. Sabin. The three scientists received the Nobel Prize in Physiology or Medicine in 1954. 1949-01-28T00:00:00+0000The first polio vaccine, developed by Jonas Salk, was tested on children from Arsenal Elementary School in Pittsburg, Pennsylvania. Nearly 2 million children in 44 states were tested. The trial showed the vaccine to be effective. The vaccine radically reduced the number of polio victims around the world.1954-02-23T00:00:00+0000Goodpasture developed a method of culturing viruses in chicken embryos and fertilized chicken eggs. Before this viruses were grown in living tissues which could be contaminated by bacteria. Goodpasture's method laid the foundation for the development of vaccines for smallpox, yellow fever, typhus and chicken pox.1960-09-20T00:00:00+0000Created by Leonard Hayflick and Paul S Moorhead.1962-01-01T00:00:00+0000Developed by Samuel Katz and John F Enders, the vaccine would later be incorporated into the MMR, a combination vaccine against measles, mumps and rubella.1963-01-01T00:00:00+0000The vaccine was made by Maurice Hilleman using material taken from his daughter, Jeryl Lynn, when she suffered measles. The Jeryl strain of the mumps vaccine is still in use today and used in the MMR vaccine.1963-01-01T00:00:00+0000The vaccine, RA27/3 had been developed by a team headed by Stanley Plotkin.1969-01-01T00:00:00+0000Stanley was an American biochemist and virologist. In 1935 he managed to crystalise the tobacco virus, the causative agent of plant disease. This was a major breakthrough because prior to this no scientists had succeeded in finding out what viruses were. His work laid the foundation for other scientists, using x-ray diffraction, to work out the precise molecular structures and reproduction process of several viruses. During World War II he managed to purify several of the most common influenza viruses and developed a vaccine that was partly effective. In 1946 he shared the Nobel Prize for Chemistry for the 'preparation of enzymes and virus proteins in a pure form.' 1971-06-15T00:00:00+0000Theiler was a South African trained physician who specialised in infectious diseases. He is best known for helping to show that yellow fever is caused by a virus and his development of a safe and effective vaccine against the disease. This work he did in the 1930s while based at the International Health Division of the Rockefeller Foundation. His first vaccine was used by the French government to protect the residents of French territories in Western Africa. The second, an improved version that was launched in Brazil in 1938. Over 400 million doses of this vaccine was given out to people over the next 60 years. Theiler was awarded the Nobel Prize for Medicine in 1951 for his yellow fever vaccine. 1972-08-11T00:00:00+00001975-01-01T00:00:00+0000AU Bertland, AA Tytell, GP Lampson, E Buynak, 'Method for purifying hepatitis B antigen'm US Patent US4017360A. The patent was granted 12 April 1977.1975-05-14T00:00:00+0000WJ McAleer, EH Wamuth, 'Process for isolating hepatitis b antigen', US Patent 4024243. The patent was granted 17 May 1977.1975-06-16T00:00:00+0000The study carried out in 12 chimpanzees indicated the vaccine would be safe to test in humans, MR Hilleman, EB Buynak, RR Roehm, AA Tytell, AU Bertland, 'Purified and inactivated hepatitis vaccine: Progress Report', American Journal of Medical Sciences, 279/2 (1975), 401-4.1975-09-01T00:00:00+0000Conducted among 1,083 gay men in New York. Gay men were ten times more likely to get hepatitis B than the normal population. Men injected with the vaccine were found to be 75% less likely to get hepatitis B than those who didn't get the vaccine. The trial was done by Wolf Szmuness at New York Medical Center using the vaccine produced by Hilleman at Merck. 1978-01-01T00:00:00+0000The vaccine was developed by Alfred Prince in partnership with John Vnek. Together they devised easier and less expensive purification steps than those used by Merck. The new vaccine required a tenth of the dose than Merck's vaccine. All these measures helped reduce the cost of the vaccine, which was 50 cents per dose. This compared with $90 to $100 for 3 doses of the Merck plasma vaccine. The low cost vaccine was licensed to Cheil Division of Samsung, Korea, Wuhan Institute in China and the Ministry of Healthy in Burma. 1978-01-01T00:00:00+0000The patent was filed on the basis of work undertaken by Kenneth Murray. 1978-12-22T00:00:00+0000The work, funded by Biogen, was undertaken as part of a project to develop recombinant hepatitis B vaccine. It was published in CJ Burrell, P Mackay, PJ Greenaway, PH Hofsneider, K Murray, 'Expression in Escheria Coli of hepatitis B virus DNA sequences cloned in plasmid pBR322', Nature, 279/5708 (1979), 43-47. 1979-02-01T00:00:00+0000F Galibert, E Mandart, F Fitoussi, P Tiollais, P Charnay, , 'Nucleotide sequence of the hepatitis B virus genome (subtype ayw) cloned in E. coli.
