Despite the clear benefits of vaccination, their uptake against common infectious diseases is suboptimal. In December 2020, vaccines against COVID-19 became available.
To determine factors that predict who will take the COVID-19 vaccine based on a conceptual model.
An online survey was administered twice: prior to public vaccination, and after vaccinations were available. Participants were 309 Israelis with initial data and 240 at follow-up. Baseline questionnaires measured intentions to be vaccinated and hypothesized predictors clustered in four categories: background, COVID-19, vaccination, and social factors. Self-reported vaccination uptake was measured at follow-up.
Sixty-two percent of the sample reported having been vaccinated. Intentions were strongly associated with vaccination uptake and mediated the effects of other predictors on behavior. Eighty-six percent of the variance in vaccination intentions was explained by attitudes toward COVID-19 vaccination, regret for having declined vaccination, trust in vaccination, vaccination barriers, past flu vaccination, perceived social norms, and COVID-19 representations.
Beliefs related directly to the COVID-19 vaccine explained most of the variance in intentions to vaccinate, which in turn predicted vaccination uptake.
尽管疫苗接种有明显的益处，但常见传染病的接种率仍不理想。2020 年 12 月，针对 COVID-19 的疫苗开始供应。
根据一个概念模型，确定预测谁将接种 COVID-19 疫苗的因素。
进行了两次在线调查：在公众接种疫苗之前和接种疫苗可用之后。参与者为 309 名有初始数据的以色列人和 240 名随访者。基线问卷测量了接种疫苗的意愿和假设的预测因素，这些因素分为四类：背景、COVID-19、疫苗接种和社会因素。在随访时测量了自我报告的疫苗接种率。
样本中有 62%的人报告已经接种了疫苗。意愿与疫苗接种率密切相关，并在其他预测因素对行为的影响中起中介作用。COVID-19 疫苗接种态度、对拒绝接种疫苗的后悔、对疫苗接种的信任、疫苗接种障碍、过去的流感疫苗接种、感知到的社会规范和 COVID-19 表现解释了接种意愿 86%的差异。
与 COVID-19 疫苗直接相关的信念解释了接种意愿的大部分差异，而接种意愿反过来又预测了疫苗接种率。
