By the time an African child enters school they have generally been repeatedly infected with malaria and have acquired immunity to the parasite making them less likely to die.

一个非洲的孩子在入学之前通常感染好几次了疟疾，对疟原虫有了免疫力也就不大可能死亡。

Meanwhile, they also affect the acquired immunity through the chemotaxis of leukocytes and promoting the proliferation of the immune cells to adjust the host immune system and play a protective role.

亦可通过趋化白细胞、促进免疫细胞增殖等来影响获得性免疫，从而调节宿主免疫系统发挥保护作用。
