ABSTRACT
Vaccine hesitancy remains a significant global public health challenge, contributing to delayed or refused vaccination despite the availability of safe and effective immunization services. This narrative review synthesizes evidence on interventions designed to address vaccine hesitancy across diverse populations and settings. Drawing on studies identified through PRISMA-informed search and appraisal processes, the review examines theoretical foundations, methodological approaches, and the effectiveness of behavioral, communication, community-based, policy, and digital interventions. Findings indicate that targeted health communication, motivational interviewing, reminder systems, and legislative mandates can improve vaccine uptake, though effectiveness varies across contexts and population groups. Community engagement and co-design strategies demonstrate promise in fostering trust and improving acceptance, while digital media campaigns offer wide reach in countering misinformation. However, substantial heterogeneity in study design, outcome measures, and theoretical application limits comparability and causal inference. Evidence gaps persist regarding underserved populations, low- and middle-income settings, and system-level equity-focused interventions. The review concludes that multi-component, context-sensitive strategies grounded in behavioral theory and supported by rigorous evaluation frameworks are essential for effectively addressing vaccine hesitancy and strengthening global immunization programs.
