In the ongoing battle against malaria, significant strides have been made, particularly with the rollout of malaria vaccines across Africa. As of early April 2025, 19 African countries, including Benin, Burkina Faso, Burundi, Cameroon, Central African Republic, Côte d’Ivoire, Chad, Democratic Republic of the Congo, Ghana, Kenya, Liberia, Malawi, Mozambique, Niger, Nigeria, Sierra Leone, South Sudan, Sudan, and Uganda, have integrated the RTS,S and R21 malaria vaccines into their childhood immunization programs and national malaria control strategies[1].
The World Health Organization (WHO) prequalified the RTS,S vaccine in July 2022 and the R21 vaccine in December 2023, ensuring their safety and quality. This prequalification has been pivotal in expanding the vaccine's reach, with at least 30 countries in Africa planning to introduce these vaccines into their immunization programs. The demand for these vaccines is unprecedented, but the availability of two safe and effective options is expected to meet this high demand[1].
The introduction of these vaccines has been supported by extensive pilot programs. For instance, the Malaria Vaccine Implementation Programme (MVIP), coordinated by WHO and co-funded by Gavi, the Global Fund to Fight AIDS, Tuberculosis and Malaria, and UNITAID, saw over 2 million children in Ghana, Kenya, and Malawi receive the RTS,S vaccine between 2019 and 2023. This pilot resulted in a 13% reduction in mortality among eligible children and a 22% reduction in severe malaria hospitalizations[2][5].
In addition to the widespread rollout, innovative delivery approaches are being implemented. In Mali, for example, a novel hybrid vaccine delivery method is being used, where children receive the first three doses based on age, and the fourth and fifth doses are administered seasonally ahead of high malaria transmission periods. This approach is complemented by community engagement efforts, including the use of digital tools and young volunteers to promote vaccination and counter misinformation[2].
The impact of these vaccines is part of a broader trend in reducing malaria-related mortality. According to recent data, malaria-related deaths in Africa have decreased from 808,000 in 2000 to 580,000 in 2022. Nine African countries have already eradicated malaria, and the introduction of these vaccines is expected to enhance global malaria elimination efforts, which are crucial given the threats posed by climate change, drug-resistant strains, and new variants of mosquitoes[3].
Gavi has also played a significant role in supporting these efforts, with 25 countries approved for funding to support malaria vaccine introductions as of April 2025. This financial support is critical in ensuring the vaccines reach the most vulnerable populations and in sustaining the momentum against malaria[4].
In summary, the recent rollout and ongoing expansion of malaria vaccines across Africa mark a significant milestone in the fight against this deadly disease. With robust support from global health organizations and innovative delivery strategies, these vaccines are poised to make a substantial impact on public health in regions most affected by malaria.
