    Abstract: The present invention relates to a combined measles-malaria vaccine containing different attenuated recombinant measles-malaria vectors comprising a heterologous nucleic acid encoding several Plasmodium falciparum antigens. Preferably, it relates to viral vectors that comprise nucleic acids encoding the circumsporozoite (CS) protein of P. falciparum, the merozoite surface protein 1 (MSP-I) of P. falciparum, and its derivatives (p-42; p-83-30-38) in its glycosylated and secreted forms, and apical membrane antigen 1 (AMAl) of P. falciparum, in its anchored or secreted form. The viral vector stems from an attenuated measles virus, based on a strain that is used as a vaccine and is efficient in delivering the gene of interest and that binds to and infects the relevant immune cells efficiently. In a preferred embodiment, the CS, the MSPl and the AMAl proteins are generated from the virus such that they will give rise to a potent immune response in mammals, preferably humans; the expression of the proteins is elevated due to human codon optimisation. Furthermore, the invention relates to the use of the recombinant vaccine in the prophylactic treatment of malaria.

    Abstract translation: 本发明涉及含有不同减毒重组麻疹 - 疟疾载体的麻疹 - 疟疾联合疫苗,其包含编码恶性疟原虫抗原的异源核酸。 优选地,它涉及病毒载体,其包含编码恶性疟原虫的环子孢子(CS)蛋白,恶性疟原虫的裂殖子表面蛋白1(MSP-1)及其衍生物(p-42; p-83- 30-38)以其糖基化和分泌形式,以及恶性疟原虫的顶膜抗原1(AMA1),以其锚定或分泌形式存在。 该病毒载体来源于减毒麻疹病毒,其基于用作疫苗并有效递送感兴趣基因并且有效结合并感染相关免疫细胞的菌株。 在一个优选的实施方案中,CS,MSP1和AMA1蛋白由病毒产生,从而它们会在哺乳动物,优选人类中产生有效的免疫应答; 由于人类密码子优化,蛋白质的表达升高。 此外,本发明涉及该重组疫苗在预防性治疗疟疾中的用途。
