Vaccine

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

Researchers find plasma donors with broad malaria protection

Malaria, caused by Plasmodium falciparum, remains a major global health threat, claiming 600,000 lives annually, mostly young children in sub-Saharan Africa. Immunity to severe malaria develops after repeated infections and is mediated by antibodies blocking the parasite's highly diversified PfEMP1 adhesion proteins from binding to the human endothelial protein C receptor (EPCR) on blood vessel walls.
