Immunization programs have been challenged by vaccine crises. Between 2013 and 2018, China has experienced three major vaccine scandals and crises, which has partly impaired Chinese public trust in domestically produced vaccines. This study aims to explore the associations between parental trust toward CDC-released crisis communication information, parents' critical understanding of crisis information, parental confidence in vaccine efficacy, and parental vaccine decisions. A cross-sectional survey was conducted among 1065 expectant parents two weeks after the 2018 vaccine crisis was revealed. The proportion of parental hesitancy toward domestically produced vaccines and overall vaccination increased from 30.6% to 82.7% and 8.3% to 52.1%, respectively, after the crisis. Parents with higher levels of trust toward crisis communication information were less likely to report vaccine hesitancy toward both domestically produced vaccines and vaccines overall after the crisis. Parents with better critical understanding of crisis information were less likely to report a vaccine hesitancy toward overall vaccine and more likely to maintain a vaccine intention. Additionally, parents with lower levels of confidence in vaccine efficacy were more likely to became vaccine hesitant but were also more likely to maintain their vaccine intentions after the crisis. It is crucial to guarantee the safety of vaccines, maintain parental confidence in vaccine efficacy, and eliminate the potential risks that result in parental vaccine hesitancy. Future crisis communication strategies are encouraged to ensure timely responses to sustain public confidence.
免疫规划受到疫苗危机的挑战。2013 年至 2018 年期间，中国经历了三起重大疫苗丑闻和危机，这在一定程度上损害了中国公众对国产疫苗的信任。本研究旨在探讨父母对疾控中心发布的危机沟通信息的信任程度、父母对危机信息的批判性理解、父母对疫苗效果的信心以及父母的疫苗接种决定之间的关联。在 2018 年疫苗危机爆发两周后，对 1065 名准父母进行了横断面调查。危机发生后，对国产疫苗和总体疫苗接种犹豫不决的父母比例分别从 30.6%增加到 82.7%和从 8.3%增加到 52.1%。对危机沟通信息信任程度较高的父母，在危机后报告对国产疫苗和总体疫苗接种犹豫不决的可能性较小。对危机信息批判性理解较好的父母，报告对总体疫苗接种犹豫不决的可能性较小，而保持疫苗接种意向的可能性较大。此外，对疫苗效果信心较低的父母更有可能对疫苗犹豫不决，但在危机后也更有可能保持他们的疫苗接种意向。保证疫苗的安全性，保持父母对疫苗效果的信心，消除导致父母疫苗犹豫的潜在风险至关重要。鼓励未来的危机沟通策略，以确保及时应对，维持公众信心。
