Mathuram Santosham, Johns Hopkins University

Dr. Mathu Santosham is a Professor in the Departments of International Health and Pediatrics at Johns Hopkins University. He was the Founder and Director of the Johns Hopkins Center for American Indian Health (CAIH) from April 1991 to April 2016.  He is currently the Director Emeritus of CAIH. He is also the Senior Advisor for the International Vaccine Access Center (IVAC). Dr. Santosham is internationally known for his work on oral rehydration therapy, childhood vaccines and dissemination of pediatric prophylactics to vulnerable populations worldwide. Working in partnership with Native American communities, he conducted landmark vaccine efficacy trials, including rotavirus vaccine, H. influenzae type b (Hib) conjugate vaccine, and pneumococcal conjugate vaccine. Native American children used to die from these diseases at rates 10 to 50 times the US average. Through his advocacy, these vaccines now save 3 to 5 million lives a year in the US and across the globe. In addition, Dr. Santosham worked with the White Mountain Apache Tribe to pioneer the use of oral rehydration solution (ORS), now known as “Pedialyte” in the US. Based on this evidence, ORS has become the standard of care for treating diarrheal dehydration, and is credited with saving 60 million lives since 1980. Dr. Santosham has become a global leader in the national and international dissemination of these public health strategies worldwide. For his contributions in public health, he has received several awards including: Albert Sabin Gold Medal Award, the Fries Prize for Improving Health and the Prince Mahidol Award for Public Health.
