" Researchers are to expand a clinical trial of a new malaria vaccine after promising results in a preliminary study in Burkina Faso.
The trial was designed to test safety, but researchers found that vaccinated children had high levels of protection.
Described as a "most encouraging" result, a larger study involving 800 children is now to take place in Mali.
The scientists involved say they are hopeful that the vaccine will ultimately be very cheap to produce.
Around a hundred different malaria vaccine candidates have been developed to date but the MSP3 vaccine tested in Burkina Faso is only the second one to show a substantial level of protection against the illness."
