Membrane protein having proteolytic activity obtainable from plasmodium falciparum blood schizonts and merozoites

摘要

An immunogenic composition for use as a vaccine against malaria. It comprises an enzymatically active protease with a molecular weight of 76.000 daltons, characterized by its capacity to react with protective antibodies originating from monkeys resistant to human malaria parasites, particularly to Plasmodium falciparum.
