ABSTRACT Dengue vaccines face significant challenges, including safety concerns, which contribute to vaccine hesitancy. Addressing this complex issue requires targeted strategies to overcome existing barriers. Through an extensive review of current evidence, we identified key factors contributing to vaccine hesitancy and explored strategies to enhance global vaccine uptake. Four conceptual models and five assessment tools were identified to understand and measure vaccine hesitancy.
