He has conducted numerous collaborative studies on the epidemiology, prevention and treatment and pathogenesis of respiratory infections (both viral and bacterial) in India, the Philippines, Europe and Indonesia. His work with premature infants over the past 20 years has in part led to the development and licensure of 2 products for respiratory syncytial virus (RSV) prophylaxis (RSV –IGIV, and palivizumab). These studies carried out in premature infants have assessed the effects of prevention of RSV on long term respiratory morbidity.

Wayne Sullender, MD, FAAP, Visiting Professor of Pediatrics, Section of Pediatric Infectious Disease at the University of Colorado School of Medicine.

Dr. Sullender is interested in understanding the viral causes of respiratory tract infections of children in developing countries. Working with collaborators at the All India Institute of Medical Sciences (AIIMS) in New Delhi viral etiologies of respiratory infections in children have been assessed and the molecular epidemiology of respiratory syncytial virus described. Influenza viruses are significant causes of human illness and death in developing countries and a vaccine is available to prevent influenza infections. Along with collaborators at the University of Alabama Birmingham and AIIMS, we are conducting a study to measure the ability of influenza vaccine given to children in India to protect both the children and unimmunized persons around them from influenza. It will also determine whether the best time to immunize in a country like India that has both summer and winter outbreaks of influenza is in the fall, as is done now, or whether immunization should be in the spring to protect against influenza infections in the summer These investigations are funded by the Centers for Disease Control and Prevention.
