Abstract

Des vaccins, notamment des antigènes pouvant stimuler des anticorps permettant dempêcher une invasion du parasite plasmodium dans des érythrocytes et utilisation desdits vaccins pour le traitement et/ou la prévention de la malaria. Dans un mode de réalisation, lantigène est une molécule immunogène comprenant une séquence aminoacide contiguë dune protéine antigène se liant aux érythrocytes dune souche de Plasmodium falciparum. Lorsquelle est administrée à un sujet, la molécule est capable dinduire une réponse immunitaire inhibitrice dinvasion à la source. Un procédé pour dépister la présence dun anticorps inhibiteur dinvasion Plasmodium falciparum dirigé contre un antigène se liant aux érythrocytes dune souche de Plasmodium falciparum chez un sujet est également décrit.
