[Malaria vaccine research].

In 1976 "The Immunology of Malaria Scientific Working Group" was established. The target of the organization was to study especially P. falciparum and other malaria strains antigens and then prepare a suitable vaccine against them. They carried out many experiments until the end of 1985, when they made the remarkable discovery by isolating the P. falciparum sporozoite surface antigen and named it "the Circumsporozoite" (CS) protein. Therefore they are hopeful to prepare a sporozoite vaccine in the very near future.
