In this episode of Understanding Healthcare, I sit down with Dr. Adam Ratner, Professor of Pediatrics and Microbiology at NYU Grossman School of Medicine and Director of the Division of Pediatric Infectious Diseases at NYU Langone Health. We discuss his upcoming book Booster Shots: The Urgent Lessons of Measles and the Uncertain Future of Children’s Health, the growing epidemic of vaccine hesitancy, and how to rebuild trust in science. Dr. Ratner also shares his thoughts on the ethical tensions between personal freedom and public health, the biggest infectious disease threats facing children globally, and what gives him hope for the future of healthcare.
