With a terrible virus sweeping the nation, the word “vaccine” dominated headlines for months. Not COVID-19, but polio. Not now, but the 1950s. Elder generations remember it well. But almost all have forgotten, if they ever knew, that Detroit suffered a polio epidemic three years after Dr. Jonas Salk’s “miracle drug” quelled America’s fear of a crippling disease. We talk with Dr. Peter Salk, Jonah Salk’s son, about the creation of the vaccine. We also talk with Dr. Terri Laws about the 1958 polio outbreak in Detroit and the racial disparities that worsened it.
