The Respiratory Syncytial Virus 2003 symposium took place from 8th-11th November 2003 in Stone Mountain, Georgia, and brought together more than 200 international investigators engaged in RSV research. RSV biology, pathogenesis, and clinical data, as well as RSV vaccines and antivirals, were addressed in the meeting, and this review will aim to briefly summarize and discuss the implications of new findings. The meeting also served as the inauguration of the Robert M. Chanock Award for lifetime achievement in RSV research, an award named in honor of the person who started the field of RSV research by recovering the first human RS virus from infants with severe bronchiolitis in 1956.
