 This study investigates COVID-19 vaccine demand and hesitancy by examining public vaccination intention, willingness to pay, WTP, confidence in domestically made or foreign made vaccines, and preference for domestic versus foreign made vaccines using a nationwide cross-sectional online survey conducted from May 1 to 1920. The health belief model, HBM, was used as a theoretical framework. Results show that the majority of respondents had a probably yes intent to take the COVID-19 vaccine, with the perception that vaccination decreases the chances of getting COVID-19 and not being concerned about the efficacy of new COVID-19 vaccines having the highest significant odds of a definite intention to take the vaccine. The median WTP for the vaccine was CNY-YN200-US8, with socioeconomic factors influencing the highest marginal WTP. The majority were competent in domestically made COVID-19 vaccine, with 64.2% reporting a preference for domestic over foreign made vaccines. Overall, the study demonstrates the utility of HBM constructs in understanding COVID-19 vaccination intent and WTP, and highlights the importance of improving health promotion and reducing barriers to COVID-19 vaccination.
