Polio’s Decline and the Role of Vaccination
Polio was once a widespread and feared disease in the US, with thousands of cases annually before the development of effective vaccines. The introduction of the Salk and Sabin vaccines in the 1950s and 1960s led to a dramatic decline in cases, and the disease was declared eradicated in the US in 1979.
By the late 20th century, the use of iron lungs had largely disappeared, replaced by modern ventilators. Martha Lillard’s reliance on the device persisted into the 21st century, making her a symbol of the disease’s history and the progress achieved.
Her death marks the closing chapter of a period when iron lungs were still in use, and it underscores the success of vaccination campaigns that prevented new cases for decades.
“Martha Lillard’s death marks the end of an era in polio treatment and reminds us of the importance of vaccination in disease prevention.”
