Before the polio vaccine, an average of 56,000 children a year would contract polio. In 1952, 3,000 children died. Thousands more were paralyzed due to the disease. After the polio vaccine, the disease all but disappeared. In 1961, only 161 open cases remained. https://www.who.int/news-room/spotlight/history-of-vaccination/history-of-polio-vaccination
