摘要：
A method of generating an antibody and cellular immune response against a Plasmodium in a primate, comprising administering at least 103 genetically modified live Plasmodium to the primate, wherein the genetically modified live Plasmodium is a species selected from Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, Plasmodium knowlesi, Plasmodium coatneyi, Plasmodium cynomolgi, and Plasmodium simium, and wherein the genetically modified live Plasmodium does not produce functional histamine releasing factor (HRF) protein, to thereby induce an antibody and cellular immune response against the Plasmodium in the primate. In some embodiments at least 104 genetically modified live Plasmodium is administered to the primate. An immunogenic composition for administration to a primate, comprising a at least 103 genetically modified live Plasmodium wherein the genetically modified live Plasmodium is a species selected from Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, Plasmodium knowlesi, Plasmodium coatneyi, Plasmodium cynomolgi, and Plasmodium simium, and wherein the genetically modified live Plasmodium does not produce functional histamine releasing factor (HRF) protein； and at least one pharmaceutically acceptable excipient and/or support. In some embodiments the immunogenic composition comprises at least 103 genetically modified live Plasmodium.
