Overcoming the COVID-19 pandemic in the United States will require most Americans to vaccinate against the disease. However, considerable research suggests that a significant proportion of Americans intend to forego vaccination, putting pandemic recovery at risk. Republicans are one of the largest groups of COVID-19 vaccine hesitant individuals. Therefore, identifying strategies to reduce vaccine hesitancy within this group is vital to ending the pandemic. In this study, we investigate the effectiveness of messages from co-partisan sources in reducing vaccine hesitancy. In a large (N = 3000) and demographically representative survey, we find that exposing "Middle-of-the-Road" partisans to pro-vaccine messages from co-partisan source cues reduces vaccine hesitancy. However, for those who identify as "Strong" or "Weak" partisans, we find no statistically significant differences in vaccination intentions when exposed to pro-vaccine messages from co-partisan sources. We conclude by discussing how our findings are helpful for vaccine communication efforts.
克服美国的 COVID-19 大流行将要求大多数美国人接种该疾病的疫苗。然而，大量研究表明，相当一部分美国人打算放弃接种疫苗，这使大流行的恢复面临风险。共和党人是对 COVID-19 疫苗犹豫不决的最大群体之一。因此，确定在该群体中减少疫苗犹豫的策略对于结束大流行至关重要。在这项研究中，我们研究了来自同党派来源的信息在减少疫苗犹豫方面的有效性。在一项大型（N=3000）和具有代表性的人口普查中，我们发现，让“中间派”的党派人士接触来自同党派来源的支持疫苗的信息，可以减少对疫苗的犹豫。然而，对于那些自称是“坚定”或“不坚定”的党派人士，我们发现，当他们接触到来自同党派来源的支持疫苗的信息时，在接种疫苗的意愿方面没有统计学上的显著差异。最后，我们讨论了我们的研究结果如何有助于疫苗传播工作。
