These include vaccines targeting different stages of the Plasmodium life cycle and employing various immunological strategies. For instance, some candidates focus on enhancing the immunogenicity and duration of protection by optimizing the dosing schedule. A study on fractional third and fourth doses of RTS,S/AS01 showed improved immunogenicity and sustained high protection against malaria (Regules et al., 2016). Other candidates are exploring the combination of vaccines with antimalarial drugs to enhance efficacy and provide broader protection (Seidlein et al., 2019). Additionally, research is ongoing to develop vaccines that can be co-administered with other pediatric vaccines without compromising safety or immunogenicity (Valéa et al., 2018). 5 Integrated Approaches to Malaria Control 5.1 Combining vector management and vaccination Integrated approaches to malaria control emphasize the combination of vector management and vaccination to achieve more effective and sustainable outcomes. Integrated Vector Management (IVM) is a key strategy that involves the rational use of resources for vector control, incorporating evidence-based decision-making, collaboration across sectors, and community participation (Beier et al., 2008; Shiff, 2002). Recent advancements in malaria vaccine development, including pre-erythrocytic and transmission-blocking vaccines, offer promising tools to complement vector control measures (Wang et al., 2009; Draper et al., 2018). Combining these vaccines with IVM strategies can enhance the overall effectiveness of malaria control programs by targeting both the mosquito vectors and the malaria parasites at different stages of their life cycle (Kaslow et al., 2017). 5.2 Policy and implementation Effective policy and implementation are crucial for the success of integrated malaria control strategies. Policies should promote the integration of vector management and vaccination within national malaria control programs, ensuring that resources are allocated efficiently and interventions are tailored to local contexts (Karunamoorthi, 2011; Benelli and Beier, 2017). The World Health Organization (WHO) has endorsed IVM as a global strategy for controlling vector-borne diseases, highlighting the importance of inter-sectoral collaboration, capacity-building, and community engagement (Beier et al., 2008). Successful implementation requires continuous monitoring and evaluation of vector control programs, as well as the development of innovative tools and approaches to address emerging challenges such as insecticide resistance and environmental changes (Kaslow et al., 2017; Wilson et al., 2020). 5.3 Community involvement Community involvement is a cornerstone of integrated malaria control. Engaging communities in the planning, implementation, and evaluation of vector management and vaccination programs can significantly enhance their effectiveness and sustainability (Asale et al., 2019; Ng’ang’a et al., 2021). Community-based education and mobilization efforts have been shown to improve treatment-seeking behavior, increase the use of preventive measures such as insecticide-treated nets (ITNs), and reduce malaria transmission (Asale et al., 2019). For example, in western Kenya, community participation in IVM activities, including the distribution of educational materials and the establishment of income-generating activities like fish farming, has led to significant reductions in malaria cases and increased community awareness (Figure 2) (Ng’ang’a et al., 2021). Similarly, in southwestern Ethiopia, coordinated community-based interventions have contributed to a substantial decline in malaria incidence (Asale et al., 2019). By integrating vector management and vaccination, developing supportive policies, and actively involving communities, malaria control programs can achieve more comprehensive and lasting impacts in the fight against malaria. 6 Global and Regional Perspectives 6.1 Global trends in malaria control Malaria control has seen significant advancements over the past few decades, driven by a combination of vector control, improved diagnostics, and the development of vaccines. Vector control remains a cornerstone of malaria
