Who use Jonas Salks work to expand and develop the killed virus polio vaccine?”
preparation of poliovirus given to prevent polio, an infectious disease of the nervous system. The first polio vaccine, known as inactivated poliovirus vaccine (IPV) or Salk vaccine, was developed in the early 1950s by American physician Jonas Salk. This vaccine contains killed virus and is given by injection. The large-scale use of IPV began in February 1954, when it was administered to American schoolchildren. In the following years, the incidence of polio in the United States fell from 18 cases per 100,000 people to fewer than 2 per 100,000. In the 1960s a second type of polio vaccine, known as oral poliovirus vaccine (OPV) or Sabin vaccine, …
About Jonas Salk When Dr. Jonas Salk envisioned the idea of the Salk Institute for Biological Studies, it was with the idea of creating a vibrant, intellectual community, dedicated to pursuing the kinds of scientific achievements that had made him an international figure only five years before. Jonas Salk Salk came to La Jolla following a career in clinical medicine and virology research. After obtaining his M.D. degree at the New York University School of Medicine in 1939, he was a staff physician at Mount Sinai Hospital in New York City. He then joined his mentor, Dr. Thomas Francis, as a research fellow at the University of Michigan. There, he worked to develop an influenza vaccine at the behest of the U.S. Army. In 1947, he was appointed director of the Virus Research Laboratory at the University of Pittsburgh School of Medicine. It was in Pittsburgh that Salk began to put together the techniques that would lead to his polio vaccine. He was already struck by the principle of vaccin
In just five years of research, Isabel Morgan made many contributions to the development of a polio vaccine, none greater that her creation of a killed-virus vaccine that worked on monkeys. She decided to become a homemaker rather than develop the vaccine further, but her breakthrough made Jonas Salk’s development of a polio vaccine possible. Isabel Morgan’s Early Days Isabel Merrick Morgan was born Aug. 11, 1911. She was the daughter of embryologist Thomas Hunt Morgan, who received the 1933 Nobel Prize in Physiology or Medicine for his study of chromosomes and heredity, and Lilian Vaughan Sampson, who often assisted her husband and published her own papers on genetics.
