Half of the world’s population is at risk to be effected by malaria, the illness from parasite-bearing mosquitos.
Currently, there is no truly effective method of protecting against malaria.
The new vaccine achieves 100% protection, using parasites from irradiated mosquitoes.
According to Nature:
The vaccine — called PfSPZ because it is made from sporozoites (SPZ), a stage in the life cycle of the malarial parasite Plasmodium falciparum (Pf) — uses a weakened form of the whole parasite to invoke an immune response.
Even though the parasite is weakened, it’s in its whole form, thus invoking an immune response.
Mosquito finds blood vessel
Malaria is a mosquito-borne infectious disease of humans and other animals caused by parasitic protozoans (a type of unicellular microorganism) of the genus Plasmodium. Commonly, the disease is transmitted via a bite from an infected female Anopheles mosquito, which introduces the organisms from its saliva into the person’s circulatory system. In the blood, the protists travel to the liver to mature and reproduce. Malaria causes symptoms that typically include fever and headache, which in severe cases can progress to coma or death. The disease is widespread in tropical and subtropical regions in a broad band around the equator, including much of Sub-Saharan Africa, Asia, and the Americas.
