Welcome to the mosquito insectary at the Walter Reed Army Institute of Research. It's where insects are grown and vaccines are developed. Scientists here want to create the first malaria vaccine the world has known - to protect U.S. soldiers in malaria-prone countries.
Malaria kills more than 650,000 people every year and scientists say they are close to finding a vaccine, but the method of testing for a vaccine has long been time-consuming and risky to transport.
The latest clinical trial of the world's leading malaria vaccine candidate produced disappointing results on Friday. The infants it was given to had only about a third fewer infections than a control group.
Researchers at the Burnet Institute have made a major breakthrough in the quest for a vaccine against malaria, which causes up to one million deaths each year.
