The World Health Organization has announced that the pilot phase with the STS anti-rariant vaccine, S, is having hopeful results. This phase began in 2019 and there are already over 1.2 million immunized children in Kenya, Malawi and Ghana. And they have shown that serious infections and death have been significantly reduced in the areas most affected by malaria.
For example, in Homa Bay in Kenya, on the shores of Lake Victoria, it is estimated that the prevalence of malaria in children has decreased by between 19 and 27%. In view of these results, it was decided to extend vaccination to other areas and parents were invited to take the four doses necessary to immunize children.
