摘要目的:调查在校医学生新型冠状病毒肺炎（简称“新冠肺炎”）疫苗接种意愿，并分析其影响因素，为制定针对性措施以加速疫苗接种提供参考依据。方法:2021年6月21—29日简单随机抽取上海市某医学院校，采用自填式电子问卷的方式对在校医学生展开问卷调查，采集其基本资料、新冠肺炎疫苗接种意愿、新冠肺炎防疫措施认知和新冠肺炎疫苗认知等信息，分析疫苗接种意愿并使用logistic回归探索其影响因素。结果:966名调查对象年龄（20.4±2.9）岁，女性占63.6%（614/966）。其中23.7%（229/966）的被调查者有家庭成员或亲属参与过抗疫工作或志愿者服务。90.6%（875/966）的被调查者表示非常愿意或愿意接种新冠肺炎疫苗。绝大多数被调查者认为“感染新冠肺炎是很严重的事”（94.3%，911/966）、“做好防护可以有效预防新冠肺炎感染”（92.4%，893/966）、“完全能做到新冠肺炎的各类防护措施”（73.5%，710/966）。约一半调查对象了解疫苗不良反应及禁忌证（51.8%，501/966）。对新冠肺炎疫苗的相关顾虑表现在：担心疫苗的保护力低（47.4%，458/966）、保护期限短（50.6%，489/966）、疫苗不良反应多（48.7%，470/966）。Logistic回归分析显示，认为“感染新冠肺炎是很严重的事”（ OR=5.30，95 %CI：2.60~10.81， P<0.001）、认为“做好防护可以有效预防新冠肺炎感染”（ OR=2.46，95 %CI：1.26~4.81， P=0.009）、认为“完全能做到新冠肺炎的各类防护措施”（ OR=2.55，95 %CI：1.53~4.25， P<0.001）者更愿意接种新冠肺炎疫苗，而担心疫苗质量差者则相反（ OR=0.29，95 %CI：0.13~0.65， P=0.003）。 结论:在校医学生新冠肺炎疫苗接种意愿较高，在今后应加强疫苗相关知识的宣传，以进一步提升接种意愿。

abstractsObjective:To investigate the intention of medical students to be vaccinated against COVID-19 and to analyze the influencing factors.Methods:A self-filled electronic questionnaire survey was conducted among medical students from a medical school in Shanghai randomly selected from June 21 to 29, 2021. The questionnaire contained items of basic information, intention for COVID-19 vaccination, awareness of COVID-19 prevention measures and awareness of COVID-19 vaccine. Logistic regression was used to analyze the influencing factors.Results:The average age of the 966 respondents was (20.4±2.9) years, and 63.6% (614/966) of them were female;23.7% (229/966) of them had family members or relatives who had participated in anti-pandemic work or volunteer service;90.6% (875/966) of the respondents expressed they were very willing or willing to be vaccinated against COVID-19. The majority of the respondents thought that “COVID-19 infection is very serious” (94.3%, 911/966), “good protection can effectively prevent COVID-19 infection” (92.4%, 893/966), and “they can fully implement all kinds of protection measures” (73.5%, 710/966). About half of the respondents (51.8%, 501/966) knew about the adverse reactions and contraindications of COVID-19 vaccine. The low protected capability (47.4%, 458/966), short duration of protection (50.6%, 489/966), and many side effects (48.7%, 470/966) were the major concerns about COVID-19 vaccine. Logistic regression analysis showed that people thought that “COVID-19 infection is very serious” ( OR=5.30, 95 %CI:2.60-10.81, P<0.001), thought that “good protection can effectively prevent COVID-19 infection” ( OR=2.46, 95 %CI:1.26-4.81, P=0.009), thought that “they can fully implement all kinds of protection measures” ( OR=2.55, 95 %CI:1.53-4.25, P<0.001) were more willing to receive COVID-19 vaccination. While those concerned about vaccine quality did the opposite ( OR=0.29, 95 %CI:0.13-0.65, P=0.003). Conclusions:Medical students have a high intention of vaccination against COVID-19. The vaccine-related knowledge quality should be emphasized in future publicity to further enhance the intention of COVID-19 vaccination.
