A new malaria vaccine will be tested on babies and children under five in Kenya, Ghana, and Malawi starting in 2018. The World Health Organization plans on vaccinating 360,000 children between 2018 and 2020. The vaccine would be used along with nets, repellents and other preventative measures. More than 420,000 people died from the disease in 2015, with more than 60 percent of the victims being under the age of five. British pharmaceutical company GlaxoSmithKline developed the drug Mosquirix.
