Abstract: Disclosed is a method for vaccination against a self-antigen in a human patient wherein a dose with an effective amount of a self-antigen is administered to the patient to elicit a primary immune response, characterised in that the patient is subjected to a boost administration of said self-antigen, wherein the amount of the self-antigen in the dose for the boost administration is higher than the amount of the self-antigen in the dose used in the administration for the primary immune response.

Abstract: An antigenic peptide comprises the structure X1-X2-X3-X4-X5-X6-X7-P-X9-X10-X11-X12 and is derived from amino acids 113-124 of alpha synuclein. Ac-cording to the structure: P is proline; X1 is L, K, A or S, wherein L is leucine, K is lysine, A is alanine and S is serine; X2 is E or S, wherein E and S are as defined above; X3 is D, E, K, N, A or S, wherein N is asparagine, D is aspartic acid and D, E, K, A and S are as defined above; X4 is M, A, S, L or K, wherein M is methionine and A, S, L and K are as defined above; X5 is P or A as defined above; X6 is V, A or S, wherein V is valine and A and S are as defined above; X7 is D or S as defined above; X9 is D or A as defined above; X10 is N, S or A, wherein N, S and A are as defined above; X11 is E, A or S, wherein E, A and S are as defined above; X12 is present or not and, if present, is A, K, V, S, or G wherein G is glycine and A, K, V and S are as defined above.

Abstract: Disclosed is a vaccine, preferably for use in the prevention or treatment of an interleukin 23 (IL-23) related disease, that includes a peptide bound to a pharmaceutically acceptable carrier, wherein the peptide is QPEGHHWETQQIPSLS (SEQ ID No. 103; p8322), GHHWETQQIPSLSPSQPWQRL QPEGHHWETQ (SEQ ID No. 98; p8461), TQQIPSLSPSQ (SEQ ID No. 99; p8400), QPEGHHWETQQIPSLSPSQ (SEQ ID No. 100; p9269), QPEGHHWETQQIPSLSPS (SEQ ID No. 101; p9269-C1), or QPEGHHWETQQIPSLSP (SEQ ID No. 102; p9269-C2), especially QPEGHHWETQQIPSLS (SEQ ID No. 103; p8322) and wherein the IL-23 related disease is one or more of psoriasis, psoriatic arthritis, rheumatoid arthritis, systemic lupus erythematosus, diabetes, preferably type 1 diabetes, atherosclerosis, inflammatory bowel disease (IBD)/M.
