  • Resumen

  • In a significant stride for public health, recent advancements in vaccine technology have ushered in the first effective malaria vaccine, marking a historic milestone in the fight against one of the most enduring and deadly infectious diseases. The World Health Organization has endorsed this groundbreaking vaccine, which scientists hope will drastically reduce the incidence of malaria, particularly in sub-Saharan Africa where the disease poses a major health crisis.

    Malaria, caused by Plasmodium parasites transmitted through the bites of infected female Anopheles mosquitoes, remains a formidable health challenge, particularly in lower-income countries. According to the World Health Organization, there were an estimated 241 million cases of malaria worldwide in 2020, resulting in about 627,000 deaths. The majority of cases (95%) and deaths (96%) occurred in the African Region.

    The RTS,S/AS01 (RTS,S) vaccine, developed by GlaxoSmithKline over several decades, is the first, and so far only, vaccine that has demonstrated the capability to significantly reduce malaria, and life-threatening severe malaria, in clinical trials. The vaccine acts against Plasmodium falciparum, the most deadly malaria parasite globally and the most prevalent in Africa. In pivotal phase 3 clinical trials, RTS,S was shown to prevent approximately 4 in 10 malaria cases among children who received four doses of the vaccine.

    The implementation of this vaccine in pilot programs in Ghana, Kenya, and Malawi has shown promising results. These pilot programs, reaching more than 800,000 children since 2019, have not only demonstrated the feasibility of delivering four doses of the vaccine in real-world settings but also showed a significant reduction in severe malaria cases. The data gathered from these initiatives have encouraged the countries to integrate RTS,S into their national malaria control programs.

    Moreover, the introduction of this vaccine is expected to have broader socio-economic benefits. By reducing the incidence of malaria, it can lessen the load on healthcare systems, increase school attendance, and improve childhood survival rates, potentially altering the life course of millions of children in the region.

    Global health leaders are now advocating for an increase in investment and production of the RTS,S vaccine, alongside existing anti-malaria interventions like bed nets and antimalarial drugs. A combination of these tools is seen as the best strategy to control, and eventually eradicate, malaria.

    As other pharmaceutical companies and research institutions continue their work on next-generation malaria vaccines, which promise even higher efficacy and longer-lasting protection, the RTS,S vaccine represents an immediate, if partial, victory against a disease that has plagued humanity for millennia. With collective global efforts and substantial funding, the fight against malaria enters a hopeful new phase.
