广泛接种疫苗是实现群体免疫的必要条件。然而，在COVID-19疫苗接种计划的前六个月，美国各州的接种率各不相同。错误信念可能在疫苗犹豫中发挥重要作用，需要了解错误信息，信念，行为和健康结果之间的关系。在这里，我们调查了COVID-19疫苗接种率和疫苗犹豫与网上有关疫苗的错误信息水平的相关程度。我们还寻找从网上错误信息到疫苗犹豫的方向性证据。我们发现错误信息和疫苗接种率之间存在负相关关系。网上的错误信息也与调查数据中的疫苗犹豫率有关。考虑到政治、人口和社会经济因素，疫苗结果和错误信息之间的关联仍然很大。虽然疫苗犹豫与共和党的投票份额密切相关，但我们观察到，在线错误信息对犹豫的影响在民主党县而不是共和党县最强。格兰杰因果关系分析表明，从网上的错误信息到疫苗犹豫之间存在方向性关系。我们的研究结果支持需要采取干预措施来解决错误信念，使个人能够做出更明智的健康决策。
Widespread uptake of vaccines is necessary to achieve herd immunity. However, uptake rates have varied across U.S. states during the first six months of the COVID-19 vaccination program. Misbeliefs may play an important role in vaccine hesitancy, and there is a need to understand relationships between misinformation, beliefs, behaviors, and health outcomes. Here we investigate the extent to which COVID-19 vaccination rates and vaccine hesitancy are associated with levels of online misinformation about vaccines. We also look for evidence of directionality from online misinformation to vaccine hesitancy. We find a negative relationship between misinformation and vaccination uptake rates. Online misinformation is also correlated with vaccine hesitancy rates taken from survey data. Associations between vaccine outcomes and misinformation remain significant when accounting for political as well as demographic and socioeconomic factors. While vaccine hesitancy is strongly associated with Republican vote share, we observe that the effect of online misinformation on hesitancy is strongest across Democratic rather than Republican counties. Granger causality analysis shows evidence for a directional relationship from online misinformation to vaccine hesitancy. Our results support a need for interventions that address misbeliefs, allowing individuals to make better-informed health decisions.
