An immunogenic composition for a vaccine against human malaria. The composition contains one or more polypeptides that can be extracted from a schizont form of a human-malaria parasite such as a Plasmodium falciparum. The polypeptides have a molecular weight of 40,000 to 140,000, and they react with protective antibodies which come from a monkey resistant to the malaria parasite and which can, by in vivo transfer to a monkey sensitive to the parasite, protect the sensitive monkey against the parasite. |
