A respiratory syncytial virus vaccine (RSV vaccine) is a vaccine which prevents infection by respiratory syncytial virus. , no licensed vaccine against RSV exists. Attempts to develop an RSV vaccine began in the 1960s with an unsuccessful inactivated vaccine developed by exposing the RSV virus to formalin (formalin-inactivated RSV (FI-RSV)). This vaccine induced a phenomenon that came to be known as vaccine-associated enhanced respiratory disease (VAERD), in which children who had not previously been exposed to RSV and were subsequently vaccinated would develop a severe form of RSV disease if exposed to the virus itself, including fever, wheezing, and bronchopneumonia. Some eighty percent of such children (vs. 5% of virus-exposed controls) were hospitalized, and two children died of lethal lung inflammatory response during the first natural RSV infection after vaccination of RSV-naive infants.

Vaccine
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease.
