The present invention relates to a liposomal vaccine composition comprising: a peptide antigen displayed on the surface of the liposome; a peptide comprising a T-cell epitope; and an adjuvant; wherein the peptide antigen comprises, consists essentially of or consists of the structure: X1-X2-X3-E-X4-X5-P-V-D-P-D-N-E-X6, wherein: E is glutamic acid, P is proline; V is Valine, D is aspartic acid, N is asparagine; X1 is present or not and, if present, is G, wherein G is glycine; X2, is present or not and, if present, is G, wherein G is defined as above; X3 is L, K, or S, wherein L is leucine, K is lysine, and S is serine; X4 is D, K or S, wherein D, K and S are as defined above; X5 is M, wherein M is methionine or methionine sulfoxide; X6 is A, K or S, wherein A is alanine and K, and S are as defined above; with the proviso that X3-E-X4-X5-P-V-D-P-D-N-E-X6 is not L-E-D-M-P-V-D-P-D-N-E-A, and which comprises between 1 and 5 amino acid differences compared with the amino acid sequence G-I-L-E-D-M-P-V-D-P-D-N-E-A, and wherein the peptide antigen does not comprise the dipeptide Y-E immediately following X6, wherein Y is tyrosine and E is as defined above.
