浙江省≥60岁人群新冠疫苗接种意愿和影响因素

目的  了解浙江省≥60岁人群新型冠状病毒疫苗(简称新冠疫苗)的接种意愿及其影响因素。方法  2020年9月1日—2020年11月30日采用分层抽样法对浙江省≥60岁人群进行问卷调查，收集基本信息、接种意愿、COVID-19风险意识等信息，采用χ²检验比较各组接种意愿率的差异，并用多因素Logistic回归分析模型分析接种意愿的影响因素。结果  共1 858名≥60岁老年人完成调查，其新冠疫苗免费接种、自费接种的意愿率分别为88.3%和66.1%。多因素Logistic回归分析模型显示，对于免费接种，居住在乡村(OR=1.6，95% CI：1.2~2.2)、无外出(OR=1.6，95% CI：1.1~2.3)、听说过COVID-19(OR=3.7，95% CI：2.4~5.8)、认为COVID-19会造成严重后果(OR=2.3，95% CI：1.6~3.5)的老年人接种意愿更高。愿意自费接种的主要原因是认同新冠疫苗的安全性和有效性；不愿意自费接种的原因主要包括新冠疫苗需要收费和担心新冠疫苗的不良反应。结论  浙江省≥60岁人群新冠疫苗免费接种意愿较高，但仍应加强关于新冠疫苗知识的宣传教育，并落实全民免费接种政策，以增强该人群接种疫苗的依从性。

A survey on the willingness and influencing factors of the COVID-19 vaccination among people aged 60 years and above in Zhejiang Province

  Objective  To understand the willingness and influencing factors of COVID-19 vaccination among people aged 60 years and above in Zhejiang Province.  Methods  A questionnaire survey was conducted from September to November 2020 using stratified sampling among population aged 60 years and above in Zhejiang Province. Socio-demographic information, willingness to receive COVID-19 vaccine and awareness of the risks of COVID-19 were collected. Chi-square test and multivariate Logistic regression were used to explore the factors associated with vaccination willingness.  Results  A total of 1 858 participants were completed the questionnaire. The vaccination willingness rate for the free vaccination and self-pay vaccination for COVID-19 vaccine were 88.3% and 66.1%, respectively. Multivariate Logistic regression showed that for free vaccination, those who lived in the country (OR=1.6, 95% CI: 1.2-2.2)、did not go outside(OR=1.6, 95% CI: 1.1-2.3)、had heard of COVID-19 (OR=3.7, 95% CI: 2.4-5.8), and believed that SARS-CoV-2 could cause serious consequences (OR=2.3, 95% CI: 1.6-3.5) had higher willingness of vaccination. For self-pay vaccination, the main reasons for receiving COVID-19 vaccine were their agreement with the safety and efficacy of the COVID-19 vaccine, while the main reasons for reluctance of vaccine were considered with the fee and side effects.  Conclusions  The willingness of COVID-19 vaccination is at a relatively high level among people aged 60 years and above in Zhejiang Province. However, further education should be concerned for the promotion of the vaccination.
