WHO approved the new “Made in Burkina” vaccine against malaria

The World Health Organization (WHO) has approved and recommended a new vaccine to prevent malaria in children. R21/Matrix-M immunizes children against this disease, and is deemed "safe and effective".

The WHO director presented the new vaccine as a major step forward in the fight against malaria, a disease that is endemic in several countries. In Africa, the disease is one of the main causes of infant mortality.

Malaria, which is transmitted by mosquitoes, hits children particularly hard in the African region, where almost half a million die from the disease every year. In 2021, the various means of combating the disease have not prevented 247 million cases worldwide, including 95% in Africa. This illustrates the salutary nature of this new vaccine.

According to Prof. Halidou Tinto, Director of the Nanoro Clinical Research Unit (Burkina-Faso) and the main player in R21 research, in partnership with three other institutions, this vaccine will make a considerable contribution to the elimination of malaria.

The R21 vaccine is the second malaria vaccine recommended by the WHO, following the RTS, S/AS01 vaccine, which the Organization recommended in 2021. Both vaccines have been found to be safe and, if administered on a large scale, should have a definite impact on public health.
