Hesitancy towards the COVID-19 vaccine remains high among the US population. Now that the vaccine is available to priority populations, it is critical to convince those that are hesitant to take the vaccine. Public health communication about the vaccine as well as misinformation on the vaccine occurs through a variety of different information channels. Some channels of information are more commonly found to spread misinformation. Given the expansive information environment, we sought to characterize the use of different media channels for COVID-19 vaccine information and determine the relationship between information channel and vaccine acceptance. We used quota sampling of vaccine priority groups [N = 2,650] between December 13 and 23, 2020 and conducted bivariate chi-squared tests and multivariable multinomial logistic regression analyses to determine the relative impact of channels of information on vaccine acceptance. We found traditional channels of information, especially National TV, National newspapers, and local newspapers increased the likelihood of vaccine acceptance. Individuals who received information from traditional media compared to social media or both traditional and social media were most likely to accept the vaccine. The implications of this study suggest social media channels have a role to play in educating the hesitant to accept the vaccine, while traditional media channels should continue to promote data-driven and informed vaccine content to their viewers.
在美国人群中，对接种 COVID-19 疫苗的犹豫不决仍然很高。现在疫苗可优先提供给某些人群，因此，说服那些犹豫不决的人接种疫苗至关重要。有关疫苗的公共卫生宣传以及有关疫苗的错误信息会通过各种不同的信息渠道传播。某些信息渠道更常被发现传播错误信息。鉴于信息环境广泛，我们试图描述用于 COVID-19 疫苗信息的不同媒体渠道的使用情况，并确定信息渠道与疫苗接受度之间的关系。我们于 2020 年 12 月 13 日至 23 日使用疫苗优先人群的配额抽样（N=2650），并进行了双变量卡方检验和多变量多项逻辑回归分析，以确定信息渠道对疫苗接受度的相对影响。我们发现传统的信息渠道，尤其是国家电视台、全国性报纸和地方性报纸，增加了疫苗接种的可能性。与社交媒体或传统媒体和社交媒体都获得信息的人相比，从传统媒体获得信息的人更有可能接受疫苗。这项研究的意义表明，社交媒体渠道在教育犹豫不决的人接受疫苗方面发挥了作用，而传统媒体渠道则应继续向观众传播基于数据和明智的疫苗内容。
