(1) Background: It is important to improve vaccination strategies and immunization programs to achieve herd immunity to infectious diseases. (2) Methods: To assess the acceptance of COVID-19 vaccination, we conducted face-to-face surveys and online surveys in Shanghai, Zhejiang, and Qinghai provinces. A fixed-effect model and a random effects model were used to analyze factors associated with the acceptance of COVID-19 vaccination. (3) Findings: We initially recruited 3173 participants, 3172 participants completed the full questionnaire (the response rate was nearly 100%), of which 2169 were valid questionnaires, with an effective rate of 87.3%. The results indicated that 82.6% of participants were willing to receive vaccination when it was available in the community, and 57.2% of deliverymen, 43.3% of medical workers, 78.2% of parents of primary and secondary school children, and 72.2% of parents of preschool children were willing to receive vaccination. The models showed that participants who were male (female vs. male: OR = 1.49, 95% CI (1.12, 1.98)), 60 to 69 years-old (60–69 vs. <30: OR = 0.52, 95% CI (0.29, 0.92)), had less education (medium vs. low: OR = 1.50, 95% CI (1.05, 2.23)), had good health status (good vs. low: OR = 0.36, 95% CI (0.15, 0.88)), and had positive attitudes and trust (OR = 0.14, 95% CI (0.10, 0.20)) in vaccines approved by the National Health Commission were more likely to accept vaccination. Participants also had an increased vaccination acceptance if it was recommended by government sources, doctors, relatives, or friends. Most participants learned about COVID-19 vaccination from television, radio, and newspapers, followed by community or hospital campaigns and the internet. (4) Conclusions: Government sources and doctors could increase the acceptance of vaccination by promoting the efficacy and safety of COVID-19 vaccination by the use of mass media and emphasizing the necessity of vaccination for everyone.

机译：（1） 背景：改进疫苗接种策略和免疫计划以实现对传染病的群体免疫非常重要。（2） 方法：为了评估对 COVID-19 疫苗接种的接受度，我们在上海、浙江和青海省进行了面对面调查和在线调查。固定效应模型和随机效应模型用于分析与接受 COVID-19 疫苗接种相关的因素。（3） 结果：我们初步招募了 3173 名参与者，3172 名参与者完成了完整的问卷（回复率接近 100%），其中 2169 份为有效问卷，有效率为 87.3%。结果显示，82.6% 的参与者愿意在社区接种疫苗时接种疫苗，57.2% 的送货员、43.3% 的医务工作者、78.2% 的中小学生家长和 72.2% 的学龄前儿童家长愿意接种疫苗。模型显示，男性（女性 vs. 男性：OR = 1.49,95% CI （1.12， 1.98））、60 至 69 岁（60-69 vs. <30：OR = 0.52,95% CI （0.29， 0.92））、受教育程度较低（中 vs. 低：OR = 1.50,95% CI （1.05， 2.23））、健康状况良好（良好 vs. 低：OR = 0.36,95% CI （0.15， 0.88））、 对国家卫生健康委员会批准的疫苗持积极态度和信任 （OR = 0.14， 95% CI （0.10， 0.20）） 更有可能接受疫苗接种。如果政府来源、医生、亲戚或朋友推荐，参与者对疫苗接种的接受度也会提高。大多数参与者从电视、广播和报纸上了解到 COVID-19 疫苗接种，其次是社区或医院活动以及互联网。（4） 结论：政府消息来源和医生可以通过使用大众媒体宣传 COVID-19 疫苗接种的有效性和安全性，并强调每个人都接种疫苗的必要性，从而提高对疫苗接种的接受度。
