Polio and the Iron Lung: A Brief Historical Overview
Polio was a highly infectious disease that caused paralysis and death before the development of effective vaccines. In the mid-20th century, thousands of Americans relied on iron lungs to breathe during severe cases of paralysis caused by the virus. Martha Lillard contracted polio as a child and spent decades dependent on this device.
The introduction of the Salk and Sabin vaccines in the 1950s and 1960s led to a dramatic decline in polio cases in the U.S., culminating in the disease’s near-eradication by the 1970s. The use of iron lungs declined sharply as modern ventilators replaced them. Today, very few polio survivors depend on such devices, with Lillard recognized as the last in the U.S.
The World Health Organization has led global eradication efforts, but poliovirus still circulates in some regions, making vaccination critical worldwide.
“Martha Lillard’s death signifies the closing of a chapter in medical history, symbolizing the triumph of vaccination over a once-devastating disease.”
— Dr. Susan Miller, polio historian
