Abstract
Objective: To understand public preference and immunization willingness for COVID-19 vaccine in China, and analyze influence factors, provide references for sufficient vaccination coverage. Methods: An online D-efficient discrete choice experiment was conducted from Jan 5, 2021 to Jan 12, 2021, in 1 241 people (with 1066 valid feedbacks), using choice sets with 5 vaccine attributes:protection rate, adverse effect, protection duration, convenience of vaccination, and out-of-pocket cost.Conditional Logit and panel mixed Logit models were used to analyze the effect of vaccine attributes on preferences, while random-effects Logit model was used to analyze the effect of vaccine attributes on vaccination willingness. Results: The COVID-19 vaccine with high protection rate(βefficacy 95%=1.76, P<0.001), low adverse effects(βlow risk=1.93, P<0.001), long protection duration (β5 years=0.59, P<0.001), convenient vaccination process(βconvenient=0.53, P<0.001), and less cost(βcost=0.14, P<0.001) was preferred by the public. Conclusion: Public preference and vaccination willingness for COVID-19 vaccine influenced by all 5 vaccine attributes (protection rate, adverse effect, protection duration, convenience of vaccination, and out-of-pocket cost).The efficacy and safety of the vaccine had the most significant impact. © 2021, Editorial Department of Fudan University Journal of Medical Sciences.

中国公众对COVID-19疫苗的偏好和接种意愿
目的:了解中国公众对COVID-19疫苗的偏好和免疫意愿,并分析影响因素,为充分实现疫苗接种覆盖率提供参考。方法:于2021年1月5日至2021年1月12日,对1241人(1066条有效反馈)进行在线D-efficient离散选择实验,使用包含5个疫苗属性的选择集:保护率、不良反应、保护持续时间、疫苗接种便利性和自付费用。采用条件Logit模型和面板混合Logit模型分析疫苗属性对偏好的影响,采用随机效应Logit模型分析疫苗属性对接种意愿的影响。结果:具有高保护率(β有效率95%=1.76,P<0.001)、低不良反应(β低风险=1.93,P<0.001)、保护期长(β5年=0.59,P<0.001)、接种过程方便(β方便=0.53,P<0.001)、低成本(β成本=0.14,P<0.001)的COVID-19疫苗受到公众的青睐。结论:公众对COVID-19疫苗的偏好和接种意愿受疫苗5个属性(保护率、不良反应、保护持续时间、接种便利性和自付费用)的影响。对疫苗的有效性和安全性影响最为显著。©复旦大学医学学报编辑部。版权所有。
