Malaria: A genetically attenuated parasite induces an immune response
With nearly 3.2 billion people currently at risk of contracting malaria, scientists have experimentally developed a live, genetically attenuated vaccine for Plasmodium, the parasite responsible for the disease. By identifying and deleting one of the parasite's genes, the scientists enabled it to induce an effective, long-lasting immune response in a mouse model. These findings were published in the Journal of Experimental Medicine on July 18, 2016. Ref. Source 5b.
