Malaria control efforts depend mainly on things like chemically-treated mosquito nets and sprays designed to kill the disease-carrying insects. But scientists in Kenya say another method -- a vaccine -- will be available next year. Researchers are already testing the vaccine on volunteers. If tests are successful, the treatment could add an important new weapon in efforts to control and possibly stop the disease.
Malaria kills more than 500,000 people a year worldwide. The disease sickens millions more every year. Many of those who die or become sick are children living in African countries south of the Sahara Desert.
