This study was conducted to ascertain whether people in China would be willing to pay for an inactivated COVID-19 vaccine booster dose. An online survey estimating participants' willingness to pay (WTP) for a booster dose of COVID-19 vaccine was conducted in Taizhou, China. The participants received ane-mail or e-poster on WeChat. A total of 1576 subjects participated the survey. A total of 66.4% (1046/1576) of the respondents were willing to pay for a booster dose of COVID-19 vaccine for themselves. Using binary logistic regression analysis, the following factors were significantly related to a WTP for a booster dose of COVID-19 vaccine: 1) confidence in the safety of the COVID-19 vaccines (high vs. low, OR: 4.30, 95%CI: 1.61-11.43), 2) confidence in the preventive effectiveness of the COVID-19 vaccines against SARS-CoV-2 virus (moderate vs. little, OR: 1.76, 95%CI: 1.30-2.38; great vs. little, OR: 2.244, 95%CI: 1.62-3.12), and 3) COVID-19 vaccine hesitancy (unhesitant vs. very unhesitant, OR: 0.67, 95%CI: 0.45-1.02; hesitant vs. very unhesitant, OR: 0.29, 95%CI: 0.19-0.44; very hesitant vs. very unhesitant, OR: 0.09, 95%CI: 0.03-0.27). This study revealed that a moderate proportion of participants responded that they would be willing to pay for a booster dose of COVID-19 vaccine. These findings suggest the importance of a detailed assessment and a health education plan that better understands the population's risk perception as well as the potential health risks in China.
这项研究旨在确定中国人是否愿意为新冠灭活疫苗加强针付费。在中国台州进行了一项在线调查，估计参与者对新冠疫苗加强针的支付意愿（WTP）。参与者通过电子邮件或微信电子海报收到调查。共有 1576 名受试者参与了调查。共有 66.4%（1046/1576）的受访者愿意为自己支付新冠疫苗加强针的费用。使用二元逻辑回归分析，以下因素与对新冠疫苗加强针的 WTP 显著相关：1）对新冠疫苗安全性的信心（高与低，OR：4.30，95%CI：1.61-11.43），2）对新冠疫苗预防 SARS-CoV-2 病毒有效性的信心（中等与少，OR：1.76，95%CI：1.30-2.38；大与少，OR：2.244，95%CI：1.62-3.12），3）对新冠疫苗的犹豫（不犹豫与非常不犹豫，OR：0.67，95%CI：0.45-1.02；犹豫与非常不犹豫，OR：0.29，95%CI：0.19-0.44；非常犹豫与非常不犹豫，OR：0.09，95%CI：0.03-0.27）。这项研究表明，相当一部分参与者表示愿意为新冠疫苗加强针付费。这些发现表明，需要进行详细评估和健康教育计划，以更好地了解中国民众的风险认知以及潜在的健康风险。
