Children aid malaria1 vaccine2 hunt

Summary

23 May 2014

A group of children in Africa who are naturally immune to malaria are helping3 scientists to develop a new vaccine. The US team published the results of their research in the journal Science.

Reporter:

Rebecca Morelle

Report

In an area of Tanzania where malaria is rife4, scientists have found a small group of children who are naturally resistant5 to the disease. Tests revealed that their immune system produces an antibody that attacks the malaria-causing parasite6.

It traps the tiny organism in red blood cells, preventing it from bursting out and spreading throughout the body. The team found that injecting a form of this antibody into mice protected the animals from malaria.

The scientists say the results are encouraging but further trials in primates7 and humans are needed to fully8 assess the vaccine's promise.
