Polio Vaccine
April 16, 1955
Nationwide vaccinations against the disease begin, using Jonas Salk's vaccine.
Before the vaccine, there were about 15,000 cases of paralysis and 1,900 deaths annually from polio in the U.S.
Salk chose to not patent the vaccine in order to maximize its distribution. When asked who owned the patent, Salk replied, "Well, the people I would say. There is no patent. Could you patent the sun?" It is estimated the patent would have been worth billions had it been patented.
