The World Health Organization said on Wednesday it is recommending broad use of the world's first malaria vaccine.
WHO says the mosquito-borne infectious disease kills more than 400,000 people every year, mostly small children in Africa.
The organization has coordinated a pilot program since 2019 to give the malaria vaccine to more than 800,000 children in Ghana, Kenya and Malawi. British pharmaceutical firm GlaxoSmithKline and others say they have confirmed the efficacy and safety of the vaccine in clinical trials.
WHO says the program showed that the vaccine led to a 30-percent reduction in the chance of developing serious symptoms.
WHO Director-General Tedros Adhanom Ghebreyesus told reporters, "the vaccine, more than 30 years in the making, changes the course of public health history."
