Vaccination programs are cost-effective for preventing communicable diseases, yet vaccine events caused vaccine crises among parents nationwide, which has created challenges for current and future vaccination programs. This study aimed to investigate parents' emotional reactions (i.e., anger and anxiety) toward the 2018 vaccine event in China and explore the associations between parental emotional reactions and vaccine decision-making. A cross-sectional survey was conducted among 1,135 parents in 2018. Five-point Likert scales were provided for respondents to rank their anger and anxiety toward the event, and their vaccine-related trust and intentions before and after the event. Multiple logistic regression analyses were employed to explore the associations. Regarding the vaccine event, 576 (50.8%) and 402 (35.4%) respondents felt very angry and angry, and 310 (27.4%) and 516 (45.5%) respondents felt very anxious and anxious, respectively. Altogether, 797 (70.3%) respondents reported a lower trust in domestically produced vaccines after the event, and 704 (62.3%) respondents reported declines in intention to choose domestically produced vaccines for their children. Multiple logistic regression analyses revealed that anxiety was a predictor of lower trust and intention after the event ( < .001), anger was a predictor of lower trust ( = .005), and both were risk factors for declines in trust and intention ( < .01). This study confirmed that negative emotional reactions toward a vaccine event were important contributors for parental vaccine decisions. Health authorities and facilities are encouraged to act in a timely manner to reduce the public's negative emotions by providing rapid crisis responses.
疫苗接种计划在预防传染病方面具有成本效益，但疫苗事件在全国范围内引起了家长的恐慌，这给当前和未来的疫苗接种计划带来了挑战。本研究旨在调查家长对 2018 年中国疫苗事件的情绪反应（即愤怒和焦虑），并探讨父母的情绪反应与疫苗决策之间的关系。2018 年，对 1135 名家长进行了横断面调查。采用 5 点 Likert 量表让受访者对事件的愤怒和焦虑程度，以及事件前后对疫苗的信任和意愿进行排名。采用多因素逻辑回归分析探讨相关性。对于疫苗事件，分别有 576（50.8%）和 402（35.4%）名受访者感到非常愤怒和愤怒，310（27.4%）和 516（45.5%）名受访者感到非常焦虑和焦虑。共有 797（70.3%）名受访者报告在事件后对国产疫苗的信任度降低，704（62.3%）名受访者报告对国产疫苗为子女选择的意愿下降。多因素逻辑回归分析显示，焦虑是事件后信任度和意愿降低的预测因素（<0.001），愤怒是信任度降低的预测因素（=0.005），两者都是信任度和意愿降低的危险因素（<0.01）。本研究证实，对疫苗事件的负面情绪反应是父母疫苗决策的重要因素。鼓励卫生当局和医疗机构及时采取行动，通过提供快速危机应对，减轻公众的负面情绪。
