一种新的可能是廉价的抗疟疾疫苗首次在人体试验成功。它是在人体试验的抗疟原虫血液期的第一个疫苗,在一个发展中国家的实验室中被分离并合成出来。疟原虫的生命周期多数时间是在细胞内度过的,对免疫系统的最佳希望是在细胞外捕捉它。当蚊子注入人体子孢子即子孢子期时,第一次机会即来临。但在侵入肝细胞前,子孢子只在血液中循环几分钟。在裂殖子期疟原虫逸出肝 A new, potentially cheaper, anti-malarial vaccine succeeded in human trials for the first time. It is the first human anti-Plasmodium vaccine tested in humans and isolated and synthesized in a laboratory in a developing country. The life cycle of Plasmodium is spent in the cell most of the time, and the best hope for the immune system is to capture it extracellularly. When mosquitoes are injected into the human sporozoite sporozoite period, the first opportunity is coming. However, the sporozoites only circulate in the blood for a few minutes before invading the liver cells. In merozoites Plasmodium escapes the liver
