 In a significant milestone in the fight against malaria, recent developments have marked a crucial turning point, particularly with the rollout of malaria vaccines in several countries.

In Mali, a historic step was taken with the introduction of the R21/Matrix-M malaria vaccine. The official launch occurred on April 25, coinciding with World Malaria Day, in the commune of Kalaban-Coro near Bamako. This initiative is driven by the commitment of health workers, local communities, and religious leaders, who are pivotal in raising awareness and ensuring the vaccine's success. The R21/Matrix-M vaccine will be deployed in 19 priority health districts across five regions and will target children aged 5 to 36 months, following a five-dose vaccination schedule. This vaccine is designed to complement existing prevention tools such as seasonal malaria chemoprevention (SMC) and the use of insecticide-treated mosquito nets, as recommended by the World Health Organization (WHO)[1].

The R21 and RTS,S malaria vaccines have both been prequalified by the WHO and have shown promising results in clinical trials. Both vaccines have been proven to reduce malaria cases by more than half during the first year after vaccination, with a fourth dose in the second year of life prolonging protection. In areas of highly seasonal transmission, these vaccines can reduce malaria cases by up to 75% when combined with seasonal malaria chemoprevention[2].

As of early April 2025, 19 countries have introduced these malaria vaccines as part of routine childhood vaccinations, with further scale-up and additional roll-outs planned throughout the year. This widespread implementation is expected to save tens of thousands of young lives annually. The RTS,S vaccine, in particular, has already demonstrated substantial reductions in malaria illness and deaths in young children during large pilot implementations[2].

Uganda has also made significant strides, launching the largest malaria vaccine introduction to date, making it the 19th African country to integrate the vaccine into routine immunization campaigns. This large-scale introduction underscores the growing commitment across Africa to combat malaria through vaccination[4].

The introduction and scaling of malaria vaccines are crucial given the current challenges in global malaria elimination efforts. Despite progress in reducing malaria-related mortality, threats such as climate change, drug-resistant strains, and new variants of mosquitoes continue to pose significant hurdles. The endorsement and rollout of these vaccines are seen as key strategies to enhance global malaria elimination efforts[5].

In summary, the recent rollout of malaria vaccines in countries like Mali and Uganda marks a significant step forward in the global fight against malaria, offering new hope for reducing the burden of this disease, especially among children under five.
