Plasmodium falciparum malaria is a major global health problem, responsible for up to 1 million deaths each year. Major efforts have been made to develop an effective vaccine against this disease, to reduce the associated morbidity and mortality. There has already been considerable progress, with the first vaccine against the pre-erythrocytic stages of P. falciparum now en route to licensure. There remains, however, a strong scientific rationale for the development of a highly effective additional vaccine component against the blood stages of the parasite, which could be deployed in conjunction with partially effective control measures against the pre-erythrocytic stages. Here, recent progress in the clinical development of blood-stage vaccines is reviewed, including methods of antigen selection, the limitations of in-vitro assays for selecting vaccines for clinical development, and the results of recently published clinical trials. This review seeks to summarize recent developments in our understanding of immunity to blood-stage parasites, as well as the relevant key advances made in vaccine technologies over the last decade. The future challenges that face this field of vaccine research are also described.
恶性疟原虫疟疾是一个重大的全球健康问题,每年导致多达100万人死亡。人们已作出重大努力来研发一种针对该疾病的有效疫苗,以降低相关的发病率和死亡率。目前已经取得了相当大的进展,第一种针对恶性疟原虫红细胞前期阶段的疫苗现已进入上市许可程序。然而,开发一种针对该寄生虫血液阶段的高效附加疫苗成分仍有充分的科学依据,这种疫苗成分可与针对红细胞前期阶段的部分有效控制措施联合使用。在此,本文综述了血液阶段疫苗临床开发的最新进展,包括抗原选择方法、用于选择临床开发疫苗的体外试验的局限性以及最近发表的临床试验结果。本综述旨在总结我们对血液阶段寄生虫免疫的最新认识进展,以及过去十年疫苗技术取得的相关关键进展。同时也描述了该疫苗研究领域未来面临的挑战。
