  • Summary

  • In the ongoing global fight against malaria, several significant developments and updates have emerged recently, particularly concerning the malaria vaccine and overall malaria control efforts.

    As of the latest reports, the World Health Organization (WHO) has highlighted encouraging yet mixed trends in global malaria control. In 2023, more than 177 million malaria cases and 1 million deaths were averted worldwide, but despite these gains, the disease remains a formidable public health challenge. There were an estimated 597,000 malaria deaths and 263 million new cases in 2023, marking an increase of 11 million cases over the previous year. This increase indicates that progress towards critical targets of the WHO global malaria strategy is off track, with the global malaria incidence rate still nearly three times higher than the target needed to reach the 2025 and 2030 goals[1].

    A key component in the fight against malaria is the malaria vaccine. Recently, the WHO recommended the use of the R21/Matrix-M malaria vaccine, the second malaria vaccine to be approved after the RTS,S vaccine. The R21 vaccine was prequalified by WHO in December 2023 and has shown high efficacy, particularly in areas with highly seasonal malaria transmission. It reduces malaria cases by around 75% when given seasonally, similar to the efficacy of the RTS,S vaccine. Both vaccines are safe, effective, and highly cost-effective, especially when used in conjunction with other control interventions such as insecticide-treated nets and indoor residual spraying[2][4].

    The rollout of the R21 vaccine has begun in several countries. Mozambique has become the 11th country to introduce a malaria vaccine, with the first phase of the R21 vaccine rollout starting in 22 districts of Zambézia province. Côte d’Ivoire and South Sudan are also among the first countries to administer the R21/Matrix-M vaccine to children at risk. These initiatives mark a crucial moment in efforts to combat one of the world’s deadliest diseases[5].

    In addition to vaccine rollouts, other innovative strategies are being implemented to enhance malaria control. Digitalizing the distribution of insecticide-treated nets, for example, has shown promising results in South Sudan and Nigeria, improving the accuracy of data collection and allowing for real-time data use. Furthermore, comprehensive approaches to combat malaria outbreaks, such as the one launched by the Ethiopian government, are underway to address increasing malaria surges in certain regions[5].

    The WHO has also updated its guidelines for malaria control, including new recommendations on the use of malaria vaccines, near-patient qualitative and semiquantitative G6PD tests, and updated guidelines on primaquine and tafenoquine. These updates aim to support national malaria control programs in defining the most appropriate mix of interventions in resource-limited settings[1].

    As the global community continues to accelerate the fight against malaria, the emphasis on reaching marginalized populations and ensuring equitable access to tools and strategies remains critical. The theme of World Malaria Day 2024, "Accelerate the fight against malaria for a more equitable world," underscores this importance, highlighting that the world’s most marginalized continue to be disproportionately affected by malaria[3].

    In summary, while significant progress has been made in malaria control, particularly with the introduction and rollout of new malaria vaccines, the fight against this disease is far from over. Continued innovation, strategic implementation, and equitable access to interventions are essential to achieving the global targets and ultimately eliminating malaria.
