The first malaria vaccine is already saving lives, cutting deaths among young children by 13% in a four-year trial in sub-Saharan Africa. The vaccine, RTS,S, is seen as being only modestly effective, but a major analysis showed a 22% decrease in severe malaria among the 2 million very young children vaccinated in Ghana, Kenya, and Malawi. That decline, and the accompanying drop in mortality, would save tens of thousands of lives once RTS,S is more widely deployed, Science reported: Malaria killed 468,000 under-5s in sub-Saharan Africa in 2021. Preventing 13% of those would mean 60,000 children still alive. RTS,S and a new, cheaper, and more effective vaccine have been recommended by the World Health Organization. |
