As a promising approach to stop the escalation of the pandemic, COVID-19 vaccine promotion is becoming a challenging task for authorities worldwide. The purpose of this study was to identify the effective sources for disseminating information on the COVID-19 vaccine to promote individuals' behavioral intention to take the vaccine. Based on the Health Belief Model (HBM), this study illustrated the mechanism of how COVID-19 information acquisition from different sources was transformed into vaccination intentions via health beliefs. Using an online survey in China, the structural equation model results revealed that perceived benefits and cues to action were positively associated with COVID-19 vaccination intentions, and perceived barriers were negatively related to the intentions. However, perceived susceptibility and perceived severity had no significant relationships with the intentions. Moreover, the findings unveiled differences in the effects of acquiring information via multiple sources among traditional media, new media, and interpersonal interactions. Notably, new media and interpersonal interactions were more salient in promoting vaccination intention via health beliefs, compared with traditional media. The findings from this study will benefit health officials in terms of utilizing different information sources in vaccine programs.
作为阻止疫情升级的一种有前景的方法，新冠疫苗推广正成为全球各国政府面临的一项具有挑战性的任务。本研究的目的是确定向公众传播新冠疫苗信息的有效来源，以促进个人接种疫苗的行为意愿。基于健康信念模型（HBM），本研究阐述了从不同来源获取的新冠信息如何通过健康信念转化为接种意愿的机制。通过在中国进行的一项在线调查，结构方程模型结果显示，感知收益和行动线索与新冠疫苗接种意愿呈正相关，而感知障碍与接种意愿呈负相关。然而，感知易感性和感知严重性与接种意愿没有显著关系。此外，研究结果揭示了通过传统媒体、新媒体和人际互动等多种来源获取信息的效果存在差异。值得注意的是，与传统媒体相比，新媒体和人际互动在通过健康信念促进接种意愿方面更为显著。本研究的结果将有助于卫生官员在疫苗接种计划中利用不同的信息来源。
