#TBT - In 1894, the first Polio outbreak in the United States occurred. After dedicating more than 20 years to finding a cure, Dr. Jonas Salk, announced his success in creating the first Polio vaccine on a radio show in 1953. The vaccine was deemed safe and effective and began circulation in 1955. Several years later, Salk founded the Salk Institute for Biological Studies in La Jolla, California! 📸: @sandiegohistorycenter
