The present invention provides a vaccine comprising a peptide antigen, one terminal end being coupled to a carrier molecule, and the other terminal end of the peptide being linked to a non-immunogenic moiety such as a saccharide. The thus terminally-glycosylated conjugated-peptide provides better immune responses in mice, able to generate unique mouse antibodies specific to the core region of these linear peptide epitopes. Results from immunization of both BALB/c and A/J strain mice revealed that the terminal glycosylation led to better antibody response towards the central epitope.
