The Full Story
RTS,S, also known as Mosquirix, was the first malaria vaccine to be recommended for widespread use by the World Health Organization. Malaria is caused by Plasmodium parasites, making it very different from viral or bacterial diseases targeted by most vaccines. WHO recommended the vaccine in 2021 after years of pilot programs in Africa. A newer malaria vaccine, R21/Matrix-M, was later recommended in 2023, expanding prevention options.
