A Narrative Review of Community Acceptance of New Vaccines: Bridging Scientific Innovation with Public Trust

The development of new vaccines has revolutionized the prevention and control of infectious diseases, offering protection against both established and emerging pathogens. However, the success of vaccination programs depends not only on vaccine efficacy and safety but also on community acceptance. Public confidence in newly introduced vaccines is influenced by trust in healthcare systems, perceptions of disease risk, sociocultural beliefs, misinformation, and equitable access to immunization services. Experiences from the coronavirus disease 2019 (COVID-19) pandemic have highlighted the importance of integrating behavioral and social science into vaccine implementation strategies. This commentary examines the current landscape of community acceptance of new vaccines, discusses the key determinants influencing vaccine uptake, and emphasizes the need for transparent communication, community engagement, and evidence-based policies to strengthen vaccine confidence and improve immunization coverage worldwide.
