A new vaccine may prevent melioidosis, a disease caused by bacteria in soil and groundwater. The bacteria can cause life-threatening pneumonia or sepsis, so finding a vaccine is important.
Researchers at a university tested the vaccine in animals. The vaccinated animals showed no lung damage, and the vaccine worked against bacteria in the air, the most dangerous form.
Scientists hope to move to human trials. The bacteria live in parts of Southeast Asia and northern Australia and have recently been found in some coastal areas of the United States.
