 Title
    Selling Science – Polio and the Promise of Gamma Globulin
 Description
    In the early 1950s, Dr. William Hammon and the National Foundation for Infantile Paralysis launched a pioneering medical experiment on a previously untried scale. Conducted on over 55,000 healthy children in Texas, Utah, Iowa, and Nebraska, this landmark study assessed the safety and effectiveness of a blood component, gamma globulin, to prevent paralytic polio. The value of the proposed experiment was questioned by many prominent health professionals as it harbored potential health risks, but compromise and coercion moved it forward. Though the trial returned dubious results, it was presented to the public as a triumph and used to justify a federally sanctioned mass immunization study on thousands of families between 1953 and 1954. Indeed, the concept, conduct, and outcome of the GG study were sold to health professionals, medical researchers, and the public at each stage.
