The most important vaccine of 2021 might be for malaria
Promising results from a new trial indicate we could finally be equipped with one of the tools needed to rid us of a disease that has plagued people since the dawn of humanity, write ROX MIDDLETON, LIAM SHAW and JOEL HELLEWELL

DISEASES come in many guises. Before late 2019, there had never been a single case of Covid-19 and SARS-CoV-2 was an unknown virus. Now, less than a year and a half later, there have been millions of cases. In contrast, a disease like malaria has been with humans ever since we emerged as a species.

An early species of Plasmodium, the parasite which causes malaria, was found in mosquitoes that had been preserved in amber for nearly 30 million years. Yet this is no guide to a disease’s impact. During 2020, more people on the continent of Africa died of malaria than Covid-19.

While it took less than a year to develop a vaccine for Covid-19, a vaccine for malaria has proven near-impossible. However, that may be about to change.
