To assess the determinants and reasons for coronavirus disease 2019 (COVID-19) vaccine hesitancy in Croatia.
The data were collected through a sociological survey by using a mixed-mode approach (computer-assisted web interviewing and computer-assisted telephone interview) on a national sample of 765 adults aged 18 or above. Bivariate (χ2 test) and multivariate (binary logistic regression) statistical methods were used.
The rate of COVID-19 vaccine hesitancy was relatively high (35%), with unequal distribution across demographic groups. Binary logistic regression with demographic characteristics as predictors showed that women, younger age groups (especially 25-34-year-olds), persons residing in households with children, inhabitants of smaller settlements, and persons with lower levels of education had higher odds of vaccine hesitancy. Trust in the five main actors responding to the COVID-19 pandemic (the National Civil Protection Headquarters, Government, health care system, scientists-researchers, and media) was also a significant predictor of vaccine hesitancy. Risk perception was an even stronger predictor: persons who perceived SARS-CoV-2 infection as a small risk were more than ten times likelier to be vaccine hesitant than those who perceived it as a great risk.
Social groups that are more prone to vaccine hesitancy need to be approached through different channels and messages by taking into account their trust in institutions and risk perception.
评估克罗地亚 2019 年冠状病毒病（COVID-19）疫苗犹豫的决定因素和原因。
通过采用混合模式（计算机辅助网络访谈和计算机辅助电话访谈）对全国范围内的 765 名 18 岁及以上成年人进行社会学调查收集数据。采用双变量（卡方检验）和多变量（二项逻辑回归）统计方法。
COVID-19 疫苗犹豫率相对较高（35%），在不同人群中分布不均。以人口统计学特征为预测因子的二项逻辑回归显示，女性、年龄较小的群体（特别是 25-34 岁）、有子女的家庭居住者、居住在较小定居点的居民以及教育程度较低的人更有可能犹豫不决。对应对 COVID-19 大流行的五个主要行为者（国家民防总部、政府、医疗保健系统、科学家/研究人员和媒体）的信任也是疫苗犹豫的一个重要预测因素。风险认知是一个更强的预测因素：将 SARS-CoV-2 感染视为小风险的人比将其视为大风险的人更有可能犹豫不决。
需要通过不同的渠道和信息来接触更倾向于疫苗犹豫的社会群体，同时考虑他们对机构的信任和风险认知。
