The head of the World Health Organization, Tedros Adhanom Ghebreyesus.Tedros, says he used to "dream of the day when we would have a ... vaccine against malaria. Now, we have two."
The country's toll makes up nearly a third of the world's 619,000 malaria deaths each year. Now Nigeria has approved a new vaccine. Will it get into the arms of those who need it most?
Volunteers for the trial put an arm over a box with hundreds of mosquitoes carrying a genetically modified malaria parasite. Here's why they did it that way — and why the trial holds promise.
The vaccine couldn't have come at a more critical time, with a surge in cases and deaths from malaria during the pandemic. But its efficacy — and its schedule — are far from ideal.
A new report from the World Health Organization contains some encouraging numbers but also cause for concern, with both cases and deaths on the upswing last year. The pandemic is just one reason.
