Toppling Malaria From the Leading Killer Charts?

Malaria is transmitted by the bite of the female Anopheles mosquito. In many parts of Africa, this protozoan blood parasite kills more children, under 5 years of age, than anything else. In 2020, alone, malaria killed 600,000 Africans. That disease's impact on childhood mortality may now be slashed, by WHO approval of the R21 anti-malarial vaccine (https://www.theguardian.com/global-development/2022/jun/27/you-get-goosebumps-from-the-data-hopes-rise-for-new-malaria-vaccine-acc). R21 has been created by Oxford University's Jenner Institute. That institute also produced the Oxford/AstraZeneca vaccine for treating Covid19, at a minimalised cost. Trials with R21 in four African countries, has shown that this vaccine has a 77% efficacy in preventing malaria. This is a dramatic improvement on the performance of the only other WHO-approved anti-malarial.
