Fifty-six years ago on April 12, 1955, the Polio Vaccine was declared to be safe and effective. The Polio Vaccine, also called the Salk vaccine, was developed by Dr. Jonas Salk in 1952. Clinical trials proved to be successful and by 1955 the vaccine was given approval by the United States government.
The approval of the vaccine was a huge step in the fight against polio. Polio, a real threat to children, caused paralysis and often death. By 1957, the incidence of Polio decreased by 90%.
The March of Dimes, established by Franklin D. Roosevelt, originally focused on fighting polio. The organization aided patients stricken with polio and funded research on vaccinations.
The success of the polio vaccine eventually led the March of Dimes to shift its mission to healthy pregnancies and preventing birth defects. You can learn more about the March of Dimes, its history and mission at http://www.marchofdimes.com
