Lancet:为什么拒绝或犹豫接种新冠肺炎疫苗?

2021-02-07 MedSci原创 MedSci原创

COVID-19疫苗你接种了吗?

关于新冠肺炎COVID-19)疫苗的民意调查显示,COVID-19疫苗的犹豫性在全球范围内呈上升趋势;但是,民意调查在准备针对特定新疫苗的大规模疫苗接种运动以及评估一国人口接受度方面的作用有限。本研究旨在在法国代表性的工作年龄人群中评估疫苗特性、关于群体免疫的信息以及全科医生(GP)的建议对接种疫苗犹豫的影响。

此次调查实验于2020年7月从在线调研小组中随机选择居住在法国且无新冠病毒感染史的18-64岁成年人,根据性别、年龄、教育、家庭大小和区域进行分层。参与者完成了关于其背景和疫苗接种行为相关问题的在线调查问卷(包括既往疫苗依从性、重度COVID-19的危险因素以及对COVID-19的看法和经经历),然后根据完全因子设计将其随机分至三组,予以不同的群体免疫相关信息(>50%的18-64岁成年人需免疫[感染或接种疫苗]、>50%的18-64岁成年人需免疫[感染或接种疫苗]、或无任何相关信息);再将受试者随机分至两组,GP推荐接种疫苗或不予以建议。然后让患者完成不同疫苗特性(有效性 50%、80%、90%或100%)、重度副作用风险(1/10000或1/100000)、疫苗生产地点(EU、USA或中国)以及接种地点(GP诊所、当地药房或大型疫苗中心)假设下的一系列设计的八项离散选择任务。

根据不同原因预测的疫苗犹豫度(1)

共有1942位符合要求的成年人完成了调查问卷,其中560位(28.8%)在所有8项任务中都拒绝接种疫苗。在本研究模型中,坚决拒绝接种疫苗和犹豫不决均与女性、年龄、低教育水平、既往疫苗接种依从性差和无特定慢性病或无除了高血压以为的慢性病明显相关。坚决拒绝接种疫苗还与对COVID-19严重程度的认知降低有关;在宣传了群体免疫益处的人群中,有工作的人群接种疫苗的犹豫度低于无业人群;有过COVID-19经历(有过症状或认识的人得过COVID-19)的人群的疫苗的犹豫度也较低。

根据不同原因预测的疫苗犹豫度(2)

本研究模型预测,在开展涉及大规模疫苗接种中心和人群免疫益处宣传的大规模疫苗接种运动的情况下,还有29.4%的工作年龄的法国人坚决拒绝接种疫苗。假定疫苗为中国生产、有效性50%、重度副反应风险为1/10000时,预测的疫苗犹豫度最高(疫苗接受率 27.4%);假定疫苗为EU生产、有效性90%、重度副反应风险为1/100000时,预测的疫苗犹豫度最低(疫苗接受率 61.3%)。

综上所述,对于法国工作年龄的人群,COVID-19疫苗的接受程度取决于新疫苗的特性和国家疫苗接种策略以及其他各种原因
