The Battle Against Malaria: The Promising Role of Vaccines

In a world where malaria continues to pose a significant threat to global health, particularly in Africa, the introduction of malaria vaccines marks a significant milestone in our fight against this deadly disease.

The Menace of Malaria

Malaria is one of the biggest global health threats, with an estimated 247 million malaria cases and 619,000 malaria deaths globally in 2021, almost all of them in Africa. On this continent, the disease is one of the biggest killers of young children, with half a million children aged under five years dying each year.

The Power of Malaria Vaccines

The World Health Organization (WHO) has recommended two malaria vaccines for use in children living in moderate to high malaria transmission areas: RTS,S/AS01 and R21/Matrix-M. These vaccines have been proven safe and effective in preventing malaria in children. The RTS,S vaccine was delivered to more than 2 million children in Ghana, Kenya, and Malawi in a four-year pilot program, demonstrating a 13% reduction in all-cause mortality.

The Malaria vaccine introduction

Several countries have already introduced the malaria vaccine. Ghana, Kenya, Cameroon and Malawi were the first to introduce the RTS,S vaccine through the Malaria Vaccine Implementation Programme (MVIP) coordinated by WHO. The Central African Republic was the first to receive the R21 vaccine.

In 2023, Gavi approved the initial allocation of 18 million doses in nine countries (Benin, Burkina Faso, Burundi, Cameroon, the Democratic Republic of the Congo, Liberia, Niger, Sierra Leone, and Uganda) to enable the introduction of malaria vaccine into their routine immunization programmes.

In 2024, more countries including Benin, Liberia, and Sierra Leone have announced the launching of large-scale malaria vaccinations targeting millions of children across the three West African nations. As of April 25, 2024, more than 30 countries in the African region are scheduled to roll out malaria vaccinations over the next year through support from Gavi, the Vaccine Alliance.

A Beacon of Hope

The introduction of malaria vaccines marks a significant milestone in global health. These vaccines hold the potential to change the trajectory of malaria, preventing future outbreaks, and saving many lives. They bring us one step closer to our goal of eliminating malaria.
