Atlanta: The quest for the world`s first malaria vaccine appears to have taken a big step: A study in Africa shows experimental shots cut the risk of disease in young children by half.The initial results from a final stage of vaccine testing were released Tuesday, and the vaccine`s developers called it a milestone in helping to tame one of the world`s most devastating killers.However, the vaccine won`t be available for at least three years, as crucial further testing must be completed to see how well it works in infants and how long protection lasts. Then the vaccine must be reviewed by government agencies in Europe and in individual African countries."We still have a way to go," Tsiri Agbenyega, lead researcher for the African study, said in a conference call with reporters.The early results show the vaccine is only about 50 percent effective, significantly lower than the protection seen in more common vaccines. But some experts said it`s a vast improvement over the current situation, and could still save hundreds of thousands of lives.
