Research in Africa found a one-time dose of an experimental drug protected adults against malaria for at least six months, the latest approach in the fight against the mosquito-borne disease.
Malaria killed more than 620,000 people in 2020 and sickened 241 million, mainly children under 5 in Africa. The World Health Organization is rolling out the first authorized malaria vaccine for children, but it is about 30% effective and requires four doses.
The new study tested a very different approach — giving people a big dose of lab-made malaria-fighting antibodies instead of depending on the immune system to make enough of those same infection-blockers after vaccination.
