Which vaccine, developed in 1953, played a significant role in saving many lives?
Correct Incorrect Polio vaccine----Polio is a debilitating disease that can cause paralysis and affect the brain and spinal cord. Before the discovery of the polio vaccine, thousands of paralysis cases occurred each year in the early 1950s in the United States alone. However, thanks to the development of the polio vaccine by American physician Jonas Salk in 1953, the virus has been eradicated from the United States, and only a few cases were reported worldwide in 2016.
