Abstract Background Respiratory syncytial virus RSV is the major cause of lower respiratory tract infection in infants and young children. Although several experimental RSV vaccines are under investigation immuno therapy is the only treatment currently available. In assessing the immunogenicity of various vaccine formulations a plaque reduction neutralization assay for the evaluation of RSV neutralizing antibody has been widely used. The method produces reliable results but it is tedious and labor intensive as it relies on manual counting by laboratory personnel. To facilitate evaluation of phase II and phase III vaccine clinical trials a more rapid reliable and efficient neutralization assay is needed. Results An improved microneutralization assay for quantifying RSV neutralizing antibodies was developed using an ImmunoSpot Series I Analyzer Cellular Technology Ltd. Cleveland OH for .
