•Willingness to pay (WTP) for a dengue vaccine and its associated explanatory variables were assessed in Aceh, Indonesia.•The mean and median of WTP for a dengue vaccine are US-$ 4.04 and US-$ 3.97, respectively.•Working as civil servants and living in the city are associated with a higher WTP.•Good knowledge of dengue viruses and good attitude towards dengue are associated with a higher WTP.•Good preventive practice against dengue virus infection is associated with a higher WTP. Vaccination strategies are being considered as a part of dengue prevention programs in endemic countries. To accelerate the introduction of dengue vaccine into the public sector program and private markets, understanding the private economic benefits of a dengue vaccine is therefore essential. The aim of this study was to assess the willingness to pay (WTP) for a dengue vaccine among community members in Indonesia and its associated explanatory variables. A community-based, cross-sectional survey was conducted in nine regencies of Aceh province, Indonesia, from November 2014 to March 2015. A pre-tested validated questionnaire was used to facilitate the interviews. To assess the explanatory variables influencing participants’ WTP for a dengue vaccine, a linear regression analysis was employed. We interviewed 677 healthy community members; 476 participants (87.5% of the total) were included in the final analysis. An average individual was willing to pay around US-$ 4 (mean: US-$ 4.04; median: US-$ 3.97) for a dengue vaccine. Our final multivariate model revealed that working as a civil servant, living in the city, and having good knowledge on dengue viruses, a good attitude towards dengue, and good preventive practice against dengue virus infection were associated with a higher WTP (P
