Developing a COVID-19 vaccine is a critical strategy for combatting the pandemic. However, for vaccination efforts to succeed, there must be widespread willingness to vaccinate. Prior research has found that Black Americans, who are disproportionately impacted by COVID-19, report lower intentions to get a vaccine than do other populations. We investigate two potential contributors to this disparity: COVID-19 vaccine-related behavioral beliefs and trust in four COVID-19 information sources (mainstream media, social media, President Trump, and public health officials and agencies). Using a nationally-representative survey (n= 889), we demonstrate that differences in vaccination beliefs explain the lower vaccination intentions reported by Black participants, compared to non-Black participants. However, while trust in information sources is associated with vaccination beliefs, differences in trust do not account for the observed differences in vaccination beliefs by race. Furthermore, we find that race moderates the relationships between trust in two sources (Trump and public health officials and agencies) and vaccination beliefs. The effects of trusting these sources on COVID-19 vaccine-related beliefs are smaller among Black participants; thus trust in these sources is less consequential to their pro-vaccination beliefs. Our results suggest that trust in information sources alone does not explain the observed relationship between race and vaccination beliefs.

开发COVID-19疫苗是抗击大流行的关键策略。但是，为使疫苗接种工作取得成功，必须有广泛的接种疫苗意愿。先前的研究发现，受COVID-19影响最大的黑人美国人报告的接种疫苗的意愿低于其他人群。我们调查了造成这种差异的两个潜在因素：COVID-19疫苗相关的行为信念和对四个COVID-19信息源（主流媒体，社交媒体，特朗普总统以及公共卫生官员和机构）的信任。使用全国代表性调查（n= 889），我们证明了接种观念上的差异可以解释，与非黑人参与者相比，黑人参与者报告的接种意愿较低。但是，尽管对信息源的信任与疫苗接种信念相关联，但信任的差异并不能解释种族之间所观察到的疫苗接种信念的差异。此外，我们发现种族缓和了对两个来源（特朗普和公共卫生官员与机构）的信任与疫苗接种信念之间的关系。在黑人参与者中，信任这些来源对与COVID-19疫苗相关的信念的影响较小。因此，对这些来源的信任与其疫苗接种观念无关紧要。我们的结果表明，仅对信息源的信任并不能解释观察到的种族和疫苗接种信念之间的关系。
