English: Headstone of Dr. Albert Bruce Sabin in Section 3 of Arlington National Cemetery, Arlington, Virginia, February 27, 2018. In the 1930s, the outbreak of polio, which led to paralysis or death, had reached epidemic proportions both in the United States and around the globe. The first inactive polio vaccine, which required an injection administered by a doctor, was created in 1954 by Dr. Jonas Salk. During the same time period, Dr. Sabin discovered that the polio virus attacked and multiplied in the intestines, as opposed to the respiratory tract as was previously believed. Dr. Sabin began testing a new polio vaccine on humans, starting with his own family. Dr. Sabin received the National Medal of Science in 1970 for his work up to and including the development of the oral polio vaccine. He also received the Presidential Medal of Freedom from Ronald Reagan in 1986, which is highest award that an American civilian can receive.
