BACKGROUND: Vaccine trust is essential for achieving high coverage rates and sustaining immunization programs worldwide. However, hesitancy intensified by the COVID-19 pandemic and the spread of misinformation has challenged trust in vaccines, healthcare professionals, and institutions. This scoping review maps global evidence on the determinants, challenges, and strategies to strengthen vaccine trust.
METHOD: The review followed the JBI Brazilian Centre for Evidence-Based Health Care methodology and the PRISMA-ScR guidelines, with a protocol registered on the Open Science Framework. Searches were conducted in seven databases and additional sources. Studies that directly addressed vaccine trust in any population were included. Data extraction and analysis combined descriptive statistics with narrative synthesis.
RESULTS: A total of 66 studies published between 2020 and 2024 were included, most of them conducted in the United States and focused on COVID-19. Vaccine trust was found to be influenced by perceptions of safety and effectiveness, trust in health systems, professionals, and institutions, as well as individual beliefs and cultural factors. The pandemic increased uncertainty but also encouraged new strategies for community engagement. Health literacy and the involvement of trusted professionals were identified as key elements in strengthening trust. Evidence gaps remain concerning groups such as adolescents, older adults, migrants, and populations in vulnerable situations. Several measurement instruments were mapped, but standardization remains limited.
CONCLUSION: Vaccine trust is a complex and context-dependent phenomenon. Strengthening it requires clear communication, context-specific strategies, active community engagement, and the involvement of healthcare professionals as trusted sources. Future research should include understudied populations, use validated instruments, and assess trust-building interventions to inform more equitable and effective immunization policies.
