“Malaria cases annually number nearly 230 million, and the disease kills more than 400,000 people—mostly children—each year. Until now, the search for an effective vaccine against the parasitic disease spread by mosquitoes has been fruitless. Today, the World Health Organization (WHO) announced that it is recommending the approval of the Mosquirix malaria vaccine developed by GlaxoSmithKline. The research on this vaccine began in 1987 and was earlier this year shown to be 50 percent effective in preventing malaria infections in the first year of Phase III clinical trials in children in three African countries.
Compared to the 95 percent efficacy of mRNA COVID-19 vaccines, 50 percent may not sound like much, but a 2020 modeling study estimated that rolling out the vaccine in the areas with the higher prevalence of the illness could prevent 5.3 million cases and 24,000 deaths annually.”
