An immunogenic particle comprises a plurality of first peptide monomers and a plurality of second peptide monomers, each of said first peptide monomers comprising : an amino acid sequence corresponding to a substantial portion of a peptide which upon secretion will form particles which are at least 10 nm in diameter, and an amino acid sequence corresponding to a heterologous epitope, each of said second peptide monomers comprising an amino acid sequence corresponding to a substantial portion of a peptide which upon secretion will form particles which are at least 10 nm in diameter, each of said second peptide monomers being free of an amino acid sequence corresponding to a heterologous epitope, wherein said first peptide monomer and said second peptide monomer are not identical but are capable of binding together. |
