The study aims to explore the relationship of vaccination service accessibility, social norms, and perceived usefulness on the intention to get the herpes zoster vaccine (HZV) among middle-aged and elderly, and to provide suggestions for promoting the health and disease prevention of this population.A questionnaire was developed based on the Stimulus-Organism-Response (SOR) theory.Utilizing the stratified random sampling and convenience sampling methods, the investigation was conducted among ≥45 middle-aged and elderly people. A structural equation modeling approach was employed to explore the relationships among external factors, perceived usefulness and vaccination intention among the surveyed population.Results: Ultimately, a datasets consisting of 481 valid samples was obtained. Social norms and perceived usefulness were positively associated with the intentions of middle-aged and elderly individuals to receive HZV. Accessibility of vaccination services and social norms were also positively related to perceived usefulness, while accessibility showed no direct correlation with vaccination intention. Perceived usefulness was found to mediate the relationships between both accessibility and social norms with vaccination intention.Social norms and perceived usefulness are significant associated with vaccination intentions. Both vaccination services and social norms were related to vaccination intention through the mediation of perceived usefulness. This study emphasizes the role of perception in external information and willingness to vaccinate. Vaccination management should be strengthened to enhance service accessibility and reduce economic burdens. Promote a social consensus on vaccination to prevent disease. Attention to social norm contents and official channels, coupled with increased perceived usefulness, can further bolster vaccination intentions among middle-aged and elderly individuals.
