Navigating acceptance: challenges and barriers to Nipah virus vaccine uptake in Malaysia's muslim-majority context

The development of Nipah virus (NiV) vaccine offers a vital opportunity for pandemic preparedness in Southeast Asia, especially in Malaysia, where the first outbreak occurred. However, vaccine acceptance must be understood within diverse cultural, religious, and social contexts.

This review explores key challenges and barriers to NiV vaccine uptake among Malaysia's Muslim-majority population, drawing insights from past rollouts such as COVID-19 and HPV vaccines. Key issues include religious concerns, misinformation, historical hesitancy, lack of trust in health authorities, and gaps in knowledge, attitudes, and perceptions, which collectively hinder vaccine acceptance and uptake. The paper also highlights enablers namely religious endorsements, transparent communication, and culturally sensitive engagement with trusted healthcare and community leaders. Evidence-based strategies, like motivational interviewing, narrative communication, and tailored outreach, are discussed. Finally, the 7C model is introduced as a structured framework to address behavioral and psychological barriers to vaccination.

Research gaps remain in understanding local psychological drivers, religious governance dynamics, and misinformation patterns. Future efforts should prioritize nationwide KAP studies, validation of behavioral frameworks such as the 7C model, and interventional research on culturally tailored communication. Integrating early halal certification and coordinated religious engagement will be essential for effective and equitable uptake.
