Abstract: Disclosed herein are mutant Plasmodium-species parasites that are genetically attenuated (GAP). They retain the ability to infect a host and invade host hepatocytes but subsequently their development is completely arrested within the liver stage of Plasmodium development and the parasites do not reach the blood stage of development. Vaccines and pharmaceutical compositions comprising genetically attenuated Plasmodium sporozoites as well as methods of using the same are likewise provided.

Abstract: Contemplated compositions and methods employ selected antigens form Plasmodium falciparum and can be used as a vaccine, therapeutic agent, and/or diagnostic tool. Especially preferred antigens are post-challenge immunity associated antigens that are identified via pre-infection suppressive treatment, controlled sub-symptomatic infection to develop immunity, and comparative proteomic differential analysis.

Abstract: A vaccine comprising an immunogenic preparation containing a plasmodium antigen or a fragment thereof, wherein said antigen is selected from a group consisting of PyAg2, PfAg2, PvAg2, PkAg2, PoAg2, PmAg2, PbAg2, PcAg2 and a combination thereof. A vaccination method comprising administering a priming immunization preparation containing a plasmodium antigen or fragment thereof, wherein said antigen is selected from a group consisting of PyAg2, PfAg2, PvAg2, PkAg2, PoAg2, PmAg2, PbAg2, PcAg2 and a combination thereof, and administrating a boosting immunization preparation containing said plasmodium antigen or fragment, wherein said antigen is selected from a group consisting of PyAg2, PfAg2, PvAg2, PkAg2, PoAg2, PmAg2, PbAg2, PcAg2 and a combination thereof. The vaccination method further comprising co-administration of an immune modulating drug.
