Expanding the anti-malaria toolkit

Researchers have trailed a revolutionary malaria vaccine that uses the entire malaria parasite and is delivered via the bite of a mosquito, offering a novel way to boost immunity. The next step involves developing an injectable version for broader use.

Also on the program: a mystery illness in the Democratic Republic of Congo’s Kwango Province; doctors in Brazil raise concerns over dengue spreading through contaminated blood transfusions; and an innovative temporary tattoo that can measure brain activity through hair.
