Few Americans remember when polio-stricken children relied on seven-foot-long iron cylinders to breathe.At its peak in early 1950s, polio caused more than 15,000 cases of paralysis a year and over 3,000 deaths in the US alone.In the decades that followed, a massive vaccination campaign nearly eradicated the disease from the globe.
