Dr. Walter Orenstein, MD, started his career in vaccinology as an Epidemic Intelligence Service (EIS) at the Centers for Disease Control and Prevention (CDC). He was assigned to Uttar Pradesh, in northcentral India and saw this terrible disease with a 30% case-fatality rate disappear before his eyes because of a vaccine and he shifted his career path to vaccinology. Dr. Orenstein spent 26 years at the CDC including 16 years as Director of the United States Immunization Program (1988-2004). Since then, he has spent most of his time at Emory University as Associate Director of the Emory Vaccine Center. He worked at the Bill & Melinda Gates Foundation (BMGF) from 2008-2011 as Deputy Director for Immunization Programs with a focus on polio eradication. Dr. Orenstein has had numerous opportunities to participate in national and international immunization policy making committees. He has been a co-editor of the standard textbook in vaccinology, Plotkin's Vaccines for the last 5 editions. He is a past chair of the National Vaccine Adivisory Committee (NVAC) and is the current Chair of the WHO Immunization and Vaccines-Related Implementation Advisory Committee (IVIR-AC)
