Attenuation of live respiratory syncytial virus vaccines is associated with reductions in levels of nasal cytokines.

BACKGROUND Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract illness (LRTI) in children. Several promising live-attenuated RSV vaccines are in development. Defining additional markers of attenuation could enhance clinical trials. METHODS We used clinical data, virologic data, and nasal wash (NW) specimens from 20 RSV-naive children enrolled in studies of 4 live-a...
