John Franklin Enders received the 1954 Nobel Prize in Physiology or Medicine "for their discovery of the ability of polioviruses to grow in cultures of various types of tissue". Meanwhile, Jonas Salk applied the Enders-Weller-Robbins technique to produce large quantities of poliovirus, and then developed a polio vaccine in 1952. Upon the 1954 polio vaccine field trial, whose success Salk announced on the radio, Salk became a public hero but failed to credit the many other researchers that his effort rode upon, and was somewhat shunned by America's scientific establishment. In 1954, Enders and Peebles isolated measlesvirus from an 11-year-old boy, David Edmonston.
Jonas Salk assembled, devoted himself to this work for the next seven years. The field trial set up to test the Salk vaccine was, according to O'Neill, "the most elaborate program of its kind in history, involving 20,000 physicians and public health officers, 64,000 school personnel, and 220,000 volunteers." Over 1,800,000 school children took part in the trial. When news of the vaccine's success was made public on April 12, 1955, Salk was hailed as a "miracle worker" and the day almost became a national holiday. Around the world, an immediate rush to vaccinate began, with countries including Canada, Sweden, Denmark, Norway,
