1. A composition for inducing an immune response to Toxoplasma gondii infection, the composition comprising a plurality of peptides dispersed in a pharmaceutically acceptable carrier, said peptides each comprising an N-terminal peptide antigen conjugated to a C-terminal peptide adjuvant via a protease-cleavable linker,
wherein said N-terminal peptide antigen is selected from the group consisting of SFKDILPKLSENPWQ (SEQ ID NO:19), EEVIDTMKSMQRDEE (SEQ ID NO:20), CAELCDPSNKPGHLL (SEQ ID NO:21), KRVTCGYPESGPVNL (SEQ ID NO:22), DRRPLHPGSVNEFDF (SEQ ID NO:23), and GLVAAALPQFATAAT (SEQ ID NO:24), and
wherein said C-terminal peptide adjuvant is EP67 YSFKDMP(MeL)aR (SEQ ID NO:2),
said plurality of peptides comprising at least two or more different peptides each having a different N-terminal peptide antigen.
