Led by Dr. Emmanuel "Chip" Walter, Professor of Pediatrics, the DVTU has conducted numerous studies in our infant and adolescent population. Dr. Walter is the principal investigator for the Clinical Immunization Safety Assessment (CISA) Project at Duke and the co-principal investigator for the NIAID-sponsored Vaccine and Treatment Evaluation Unit (VTEU) at Duke. Although much of Dr. Walter’s early research career was focused on pediatric HIV infection, Dr. Walter has a long standing clinical and research interest in immunization issues. Either as a principal investigator or co-investigator he has been conducting clinical vaccine studies including Phase I, II, III and IV vaccine evaluations for over 20 years. He directs the Duke Vaccine and Trials Unit (DVTU), is a member of the Duke Human Vaccine Institute, and co-directs the Duke Primary Care Research Consortium at the Duke Clinical Research Institute. Most recently he has published primarily in the field of vaccines with a particular emphasis on early childhood influenza immunization. Dr. Walter currently serves as a member for the CDC Advisory Committee on Immunization Practices.
