  7. 25. Malaria : multiclonal infections and protective immunity

    Author : Anne Liljander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The mortality and morbidity attributable to malaria remain high in Sub-Saharan Africa, especially among children less than five years of age. In areas of high transmission, immunity to clinical malaria is gradually acquired after repeated exposure to the polymorphic Plasmodium falciparum parasite. READ MORE
