Chimeric proteins are expressed, secreted or released by a bacterium to immunize against or treat a parasite, infectious disease or malignancy. The delivery vector may also be attenuated, non-pathogenic, low pathogenic, or a probiotic bacterium. The chimeric proteins include chimeras of, e.g., phage coat and / or colicin proteins, bacterial toxins and / or enzymes, autotransporter peptides, lytic peptides, multimerization domains, and / or membrane transducing (ferry) peptides. The active portion of the immunogenic chimeric proteins can include antigens against a wide range of parasites and infectious agents, cancers, Alzheimer's and Huntington's diseases, and have enhanced activity when secreted or released by the bacteria, and / or have direct anti-parasite or infectious agent activity. The activity of the secreted proteins is further increased by co-expression of a protease inhibitor that prevents degradation of the effector peptides. Addition of an antibody binding or antibody-degrading protein further prevents the premature elimination of the vector and enhances the immune response.
