  • Summary

  • In recent developments, the fight against malaria has seen significant progress, particularly with the rollout of malaria vaccines across Africa.

    As of January 2025, nearly 10 million doses of the malaria vaccine have been delivered to Africa during the first year of routine immunization. This initiative, led by the Gavi vaccine alliance, has expanded beyond the initial pilot countries of Ghana, Kenya, and Malawi to include 14 additional countries, starting with Cameroon in January 2024. The vaccine, primarily the RTS,S vaccine and more recently the R21/Matrix-M, has shown promising results. In the pilot phase from 2019 to 2023, more than two million children were vaccinated, resulting in a substantial reduction in severe malaria illness and hospitalizations, as well as a 13% drop in mortality[1][2][4].

    The World Health Organization (WHO) has recommended both the RTS,S and R21/Matrix-M vaccines for use in children living in areas with moderate to high malaria transmission. These vaccines have been proven to reduce uncomplicated malaria by about 40%, severe malaria by 30%, and all-cause mortality by 13%[2][4].

    The rollout has been particularly impactful in high-burden countries like Cameroon, where malaria claims over 13,000 lives annually and accounts for nearly 30% of all hospital consultations. Early results from Cameroon have shown reduced deaths among children under five, highlighting the vaccine's potential to transform lives in these regions[1].

    Africa bears the brunt of the global malaria burden, accounting for approximately 94% of global malaria cases and 95% of related deaths. In 2023, there were 263 million reported malaria cases, with more than half of the deaths occurring in Nigeria, the Democratic Republic of Congo, Niger, and Tanzania. Children under five are disproportionately affected, accounting for about 76% of all malaria deaths in Africa[1][5].

    Despite these challenges, there is optimism. The WHO's recommendation of the malaria vaccines has led to significant funding commitments from global health organizations such as Gavi, the Global Fund to Fight AIDS, Tuberculosis and Malaria, and Unitaid. These efforts aim to protect an additional 13 million children this year and a further 50 million children from 2026 to 2030[1][4].

    However, ongoing challenges include mosquito resistance to insecticide-treated nets, antimalarial drug resistance, and the spread of new mosquito species like *Anopheles stephensi*. These issues underscore the need for continued investment in malaria research and innovation to accelerate progress towards malaria elimination[3][5].

    In the lead-up to World Malaria Day, experts and advocates have emphasized the importance of sustained funding and bold approaches to combat the disease. Krystal Birungi, an entomologist from Uganda, recently called for increased funding to combat malaria, highlighting that despite progress, the disease remains a significant public health threat, particularly in Africa[5].

    Overall, the recent advancements in malaria vaccination represent a crucial step forward in the global effort to control and eliminate malaria, but they must be complemented by ongoing research, community engagement, and political will to address the complex and evolving challenges posed by this disease.
