The world's first malaria vaccine has been approved for field trials in three African countries - Ghana, Kenya, and Malawi - where the disease is a serious issue. Developed by GlaxoSmithKline, Newser has the Associated Press story.

The vaccine, which has partial effectiveness, has the potential to save tens of thousands of lives if used with existing measures, the WHO regional director for Africa, Dr. Matshidiso Moeti, said in a statement. The challenge is whether impoverished countries can deliver the required four doses of the vaccine for each child.

The vaccine, if it proves as effective as hoped, could also be useful for Americans traveling or living in tropical regions, including the American south - think Louisiana or Florida.
