Purpose This population-based study aimed to determine the willingness to receive a booster dose of vaccine against coronavirus disease (COVID-19) in Taizhou, China. Methods An online questionnaire investigation addressing participants' willingness to receive a booster dose of the COVID-19 vaccine was organized in Taizhou, China. Of the 2318 interviewees who received the invitation, 1576 finished a qualifying questionnaire, corresponding to a response rate of 68.0%.
