A human synthetic peptide-based influenza vaccine for intranasal administration comprises a mixture of flagella containing at least four epitopes of influenza virus reactive with human cells, each expressed individually inflagellin, said influenza virus epitopes being selected from the group consisting of: (i) one B-cell hemagglutinin (HA) epitope; (ii) one T-helper hemagglutinin (HA) or nucleo-protein (NP) epitope that can bind to many HLA molecules; and (iii) at least two cytotoxic lymphocyte (CTL) nucleoprotein (NP) or matrix protein (M) epitopes that are restricted to the most prevalent HLA molecules in different human populations.
