New preventive strategies for respiratory syncytial virus infection in children.

ABSTRACT

Respiratory syncytial virus (RSV) infections result in significant morbidity and mortality for young children worldwide. The development of preventive strategies for RSV has faced different challenges, including the legacy of the first vaccine attempt, and an incomplete understanding of the host immune response to the virus. However, promising preventive strategies against RSV are in the pipeline and their development has advanced rapidly in the past decade due in part to our improved knowledge about the structural conformation of key RSV proteins. These strategies include monoclonal antibodies and different vaccines platforms directed towards the main target populations.
