The elusive vaccine play

LONG before the Covid-19 pandemic, one of the largest mass vaccination drives conducted in the history of mankind was the inoculation of millions of children against polio in 1955.

According to Centres for Disease Control and Prevention, in the early 1940-1950s, polio disabled an average of 35,000 people a year in the United States with the majority being children. One of the most respected presidents, president Franklin. D. Roosevelt himself, suffered from polio infection and became disabled when he was 39 years old.
