needleIn the early 1950s, Dr. William McD. Hammon and the National Foundation for Infantile Paralysis (NFIP) launched a pioneering medical experiment on a scale never witnessed before. Conducted on over 55,000 healthy children in Utah, Texas, Iowa, and Nebraska, the study aimed to assess the safety and effectiveness of a blood fraction, known as gamma globulin (GG), to prevent paralytic polio. Based on the positive outcome of the experiment, a national immunization program was launched by the federal government, which became America’s first polio control effort.
