目的  了解上海市大学生接种新型冠状病毒疫苗(新冠疫苗)的意愿及影响因素。方法  选择2021年2月23日―2021年3月15日上海市四所不同学科类别院校的学生进行在线问卷调查，分析新冠疫苗接种意愿率，采用多因素Logistic回归分析模型探讨影响新冠疫苗接种意愿的因素。结果  4 462名被调查者接种意愿率为78.04%，Logistic回归分析模型结果显示，与医学类院校相比，理工科类及职业技术类院校的学生接种意愿相对较高(OR=1.53、1.50)，不认同疫苗对于保护健康是非常重要的(OR=0.11)、不认同所有在国内通过国家药品监督管理局(药监局)上市的疫苗都是安全的(OR=0.42)、周边无人接种(OR=0.68)的调查对象接种意愿低。不愿意接种的主要原因是担心疫苗的安全性(73.88%)和有效性(55.61%)。进一步调查显示，如果政府、医生、家人朋友建议接种新冠疫苗，原先选择不接种或不确定接种新冠疫苗的调查对象，表示愿意进行接种的比例分别为37.86%、48.27%、35.31%。结论  上海市大学生新冠疫苗接种意愿率较高，相关部门应做好疫苗接种协调工作，以便接种工作得以有效进行。

Analysis of willingness and influencing factors of vaccination against novel coronavirus among col-lege students in Shanghai

Objective To investigate the willingness and influencing factors with novel coronavirus vaccines(COVID-19 vaccines) among college students in Shanghai. Methods From February 23 to March 15, 2021, a web based questionnaire survey was conducted among students from four colleges to analyze the willingness rate of COVID-19 vaccines. Multivariate Logistic regression was used to analyze influencing factors of the willingness to receive vaccines. Results Of 4 462 subjects, 78.04% were willing to receive COVID-19 vaccines. Logistic regression analysis showed that students from the technology university and the vocational school had higher willingness to vaccinate(OR=1.53, 1.50), compared with those from medical college. Respondents did not agree that vaccines are important for protecting health(OR=0.11) and did not agree that all vaccines marketed through National Medical Products Administration are safe(OR=0.42) were less willing to be vaccinated. Those who had no one nearby to vaccinate against COVID-19 were less willing to be vaccinated(OR=0.68). The main reasons for refusing or hesitating to be vaccinated were concerned about the safety(73.88%) and efficacy(55.61%) of the vaccine. Further investigation showed that 37.86%, 48.27% and 35.31% of respondents who had previously chosen not to vaccinate or were unsure about vaccinating against COVID-19 were willing to vaccinate if recommended by the government, doctors, relatives and friends, respectively. Conclusion The willingness rate of COVID-19 vaccination among college students was high in Shanghai. The relevant departments should do a good job in the coordination of vaccination so that the vaccination work can be carried out effectively.
