BACKGROUND: This study attempts to understand coronavirus disease 2019 (COVID-19) vaccine demand and hesitancy by assessing the public's vaccination intention and willingness-to-pay (WTP). Confidence in COVID-19 vaccines produced in China and preference for domestically-made or foreign-made vaccines was also investigated. METHODS: A nationwide cross-sectional, self-administered online survey was conducted on 1-19 May 2020. The health belief model (HBM) was used as a theoretical framework for understanding COVID-19 vaccination intent and WTP. RESULTS: A total of 3, 541 complete responses were received. The majority reported a probably yes intent (54. 6%), followed by a definite yes intent (28. 7%). The perception that vaccination decreases the chances of getting COVID-19 under the perceived benefit construct (OR = 3. 14, 95% CI 2. 05-4. 83) and not being concerned about the efficacy of new COVID-19 vaccines under the perceived barriers construct (OR = 1. 65, 95% CI 1. 31-2. 09) were found to have the highest significant odds of a definite intention to take the COVID-19 vaccine. The median (interquartile range IQR) of WTP for COVID-19 vaccine was CNY¥200/US28 (IQR CNY¥100-500/USD14-72). The highest marginal WTP for the vaccine was influenced by socio-economic factors. The majority were confident (48. 7%) and completely confident (46. 1%) in domestically-made COVID-19 vaccine. 64. 2% reported a preference for a domestically-made over foreign-made COVID-19 vaccine. CONCLUSIONS: The findings demonstrate the utility of HBM constructs in understanding COVID-19 vaccination intent and WTP. It is important to improve health promotion and reduce the barriers to COVID-19 vaccination.
