Salk polio vaccine approved
April 12, 1955
On the tenth anniversary of FDR's death, a University of Michigan panel announced that Jonas Salk's injectable polio vaccine was safe and effective. Church bells rang across America. A disease that had paralyzed tens of thousands of children every summer was about to disappear. Salk refused to patent the vaccine; he said it belonged to the people.
