Katelyn Evans, 16, has never met Randy Kerr—and there’s no reason she should have. It was 66 years ago that Kerr, then 6, became briefly famous, receiving the first injection of Jonas Salk’s experimental polio vaccine during the massive field trial of hundreds of thousands of children in the spring of 1954.

The company had already enrolled 42,113 adult volunteers in its Phase 2 and 3 trials, but only recently did the US Food and Drug Administration (FDA) give approval to include children.
