Why measles keeps this doctor awake at night

The measles outbreak in West Texas is a harbinger for a very real public health threat America currently faces. Dr. Adam Ratner is a pediatric infectious diseases physician in New York City, and he joins host Krys Boyd to discuss the return of measles, what it does to the body — especially in young children — what it took to develop the very safe and effective vaccine we have today and what it means that vaccine hesitancy rates are rising. His book is “Booster Shots: The Urgent Lessons of Measles and the Uncertain Future of Children’s Health.”
