Malaria is a life-threatening disease that is transmitted by mosquitoes, and has caused an estimated 409,000 deaths, most of them in Africa. According to a recent BBC article, The World Health Organization has announced it will launch the world's first malaria vaccine in pilot projects in three African countries: Ghana, Kenya, and Malawi. The R21 vaccine has been under development for more than three decades and has shown promising results in clinical trials.
