  • Summary

  • In recent developments, the global fight against malaria has seen significant advancements, particularly with the implementation and expansion of malaria vaccination programs.

    As of April 2025, Uganda has launched the largest malaria vaccine introduction to date, targeting 1.1 million children under two years in 105 high- and moderate-transmission districts. This initiative, supported by Gavi, the Vaccine Alliance, UNICEF, the World Health Organization (WHO), PATH, and CHAI, marks Uganda as the 19th African country to integrate the malaria vaccine into routine immunization. The R21/Matrix-M malaria vaccine, administered in four doses, is expected to prevent at least 800 cases of severe malaria among children daily and ease the financial burden on families by reducing treatment costs[3].

    The R21/Matrix-M vaccine, recommended by the WHO in October 2023, has shown high efficacy in reducing symptomatic cases of malaria by 75% in areas with highly seasonal transmission. It also demonstrates good efficacy when given in an age-based schedule, with a 66% reduction in cases over 12 months following the first three doses. This vaccine is seen as a vital tool in bridging the demand-and-supply gap for malaria vaccines, complementing the existing RTS,S/AS01 vaccine[4].

    The WHO's recommendation of the R21/Matrix-M vaccine follows the success of the RTS,S/AS01 vaccine, which was recommended in 2021. Both vaccines have been shown to be safe and effective in preventing malaria in children, with the RTS,S/AS01 vaccine reducing clinical malaria by 39%, severe malaria by 30%, and all-cause mortality by 13% in children under five years old[2].

    Despite these advancements, the global burden of malaria remains significant. In 2023, there were an estimated 263 million malaria cases and 597,000 related fatalities worldwide, with the WHO African Region shouldering the heaviest burden. Countries such as Nigeria, the Democratic Republic of the Congo, Tanzania, and Niger account for over 50% of all malaria deaths globally[1].

    The ongoing efforts to combat malaria are also highlighted by the recent expert briefing on World Malaria Day, hosted by the Johns Hopkins Bloomberg School of Public Health. The briefing emphasized the need for continued and sustained funding for malaria control, elimination, and research, given the complex challenges posed by the disease, including drug resistance, insecticide resistance, and the impact of the COVID-19 pandemic[5].

    In summary, the introduction and expansion of malaria vaccines, coupled with ongoing research and global health initiatives, represent a critical step forward in the fight against malaria, particularly in high-burden countries in Africa. These efforts aim to protect millions of children and move closer to a malaria-free future.
