(Photo by Patrick Meinhardt/Getty Images)Patrick Meinhardt—Getty Images Malaria has long been a global scourge, killing some 500,000 people a year, more than half of them children under 5\. But that may be about to change, thanks to the introduction of a malaria vaccine—the first vaccine ever against a parasitic infection. The shot has been in the works since 1987, at a cost of more than $750 million, mostly funded by the Bill and Melinda Gates Foundation and GlaxoSmithKline. Dubbed Mosquirix, it was recommended for approval by the World Health Organization in October, after a field trial involving 800,000 children in Ghana, Kenya and Malawi. The four-dose regimen was found to cut the risk of infection by 40% and the risk of severe infection by 30%. _—Jeffrey Kluger_ ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/best-inventions-2021/6113079/malaria-vaccine/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/best-inventions-2021/6113079/malaria-vaccine/"},"headline":"A Public-Health Breakthrough","datePublished":"2021-11-10T11:08:17.000Z","dateModified":"2026-03-02T23:55:28.419Z","description":"","url":"https://time.com/collections/best-inventions-2021/6113079/malaria-vaccine/","keywords":["list","franchise","best inventions","Best Inventions 2021"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt9ac959310d6a6e51/698a1e8ad075332884e6c220/best-inventions-2021-Malaria-Vaccine.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"TIME Staff","jobTitle":null,"url":"https://time.com/author/time-staff/"}],"creator":"TIME Staff","articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt9ac959310d6a6e51/698a1e8ad075332884e6c220/best-inventions-2021-Malaria-Vaccine.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/collections/best-inventions-2021/6113079/malaria-vaccine/","name":"A Public-Health Breakthrough"}}]}] ```
