Vaccines: Questions & Answers with Paul Offit

Text by Greg Johnson

At the tender age of 5, Paul Offit, a native of Baltimore, spent several months in 1956 in the city’s Kernan Hospital for Crippled Children while recovering from a clubfoot operation. Housed with him were around 20 children crippled from polio, a debilitating and paralyzing disease for which there was a new vaccine, but one which had not yet reached popular use.

Parents of the children in the hospital, which has been renamed and is now a part of the University of Maryland Rehabilitation & Orthopaedic Institute, were only allowed to visit for one hour each week on Sunday. Offit’s mother was pregnant at the time and unable to visit him, and he can vividly recall staring out the window, awaiting his father’s weekly return.

This distressing childhood experience would remain with Offit, and guide and influence his future work in pediatrics and pediatric infectious diseases.
