Respiratory syncytial virus (RSV) is a common virus related to disease in the lung epithelium of young children and infants. However, RSV vaccine has not yet been developed. Thus it is difficult to develop a whole-RSV vaccine due to induction of Th2-type hyper-immune responses. To overcome this limitation, we used CpG-DNA encapsulated within liposome complex (Lipoplex(O)) as an adjuvant for the induction of a Th1-dominated humoral response in animal experiments. However, vaccination with a complex of UV-irradiated RSV and Lipoplex(O) had no effect against RSV infection. To improve the efficacy of the RSV vaccine, we performed peptide-based epitope screening and evaluated the efficacy of the vaccine using a complex of epitope and Lipoplex(O). Two efficient B-cell epitopes were identified in nine candidate epitopes from the RSV-F protein. The vaccination with a complex of RSV-F protein epitope (F7 and F9) and Lipoplex(O), induced a prophylactic effect on the RSV-infection based on lung histopathology and mucus clearance from the lungs. Thus, further studies on the effect of the peptide vaccine against infection by multiple RSV strains, may allow fine-tuning of a potential vaccine, and improvement of the vaccine program against RSV.
