Abstract：
Despite widely recognised effectiveness against the spread of COVID-19, vaccine hesitancy persists. This systematic literature review aimed to clarify the definition and the operationalisation of the term \'vaccine hesitancy\' and disclose the various psychosocial factors underlying this phenomenon. The results of studies conducted in European countries and in the United States after the vaccines became available were taken into account. The review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analyses statement. Twelve studies met the inclusion criteria and were reviewed. efinitions and measures of vaccine hesitancy differed across the studies, limiting their comparison. Nonetheless, by drawing on theoretical frameworks, we were able to identify several psychosocial variables in determining vaccine hesitancy. Our findings point to the need for a transdisciplinary approach to understanding the antecedents of vaccine hesitancy. A better understanding of the phenomenon may help to develop interventions and social policies to address a complex challenge such as vaccination hesitancy.
摘要：
尽管对COVID-19传播的有效性得到了广泛认可，但疫苗的犹豫仍然存在。这篇系统的文献综述旨在阐明“疫苗犹豫”一词的定义和操作，并揭示这一现象背后的各种社会心理因素。考虑了疫苗上市后在欧洲国家和美国进行的研究结果。根据系统评价和荟萃分析声明的首选报告项目进行审查。12项研究符合纳入标准并进行了综述。疫苗犹豫的确定和措施在不同的研究中有所不同，限制他们的比较。尽管如此，通过借鉴理论框架，我们能够在确定疫苗犹豫时确定几个心理社会变量.我们的发现表明需要一种跨学科的方法来理解疫苗犹豫的前身。更好地了解这一现象可能有助于制定干预措施和社会政策，以应对疫苗接种犹豫等复杂挑战。
