Bridging the intention‒behavior gap in herpes zoster vaccination: A nationwide survey in a self-payment setting.

ABSTRACT: Herpes zoster (HZ) causes substantial morbidity, yet global uptake remains suboptimal where the vaccine is excluded from universal coverage. Taiwan exemplifies such a self-payment setting, with the HZ vaccine self-financed and local government subsidies restricted to limited eligible groups. This study analyzed data from a nationwide, web-based cross-sectional survey of adults aged ≥18y fielded in 2025, examining factors associated with HZ vaccination behavior, intention, and willingness to pay (WTP).
