What is the polio vaccine?

ANSWER

The polio vaccine guards against polio, an infectious disease caused by a virus, that was once the leading cause of disability in the U.S. Since the introduction of the polio vaccine in 1955, the disease has been wiped out the U.S. But the disease is still common in some developing countries and until it's eradicated worldwide, the risk of it spreading to the U.S. still exists. For that reason, the polio vaccination remains one of the recommended childhood immunizations. In most parts of the U.S., polio immunization is required before a child can start school.
