摘要
在 COVID-19 大流行期间,反疫苗情绪以惊人的速度增长,人们的疫苗接种状况与他们所接触到的信息之间的关系还有待进一步了解。本研究调查了疫苗接种行为、决策依据和在社交媒体上接触信息的时间之间的关系。该研究采用了一项具有全国代表性的美国成年人调查,通过统计分析、网络分析和半监督主题建模相结合的方法,对三个亚群(早期接种者、晚期接种者和非接种者)进行了分析。据报告,美国人选择接种疫苗的主要原因是安全和健康。然而,与早期采用者相比,工作要求和旅行对晚期采用者更为重要(OR 的 95% CI 为 [0.121, 0.453])。虽然晚接种者和未接种者不接种疫苗的主要原因是接种时间太早,但晚接种者也更常提到安全问题,而未接种者则提到对政府的不信任(OR 的 95% CI 为 [0.125, 0.763])。在分享 Twitter/X 账户的人群中,早期接种者和未接种者比晚期接种者关注了更多党派色彩浓厚的政治账户,而晚期接种者比未接种者接触了更多中立和支持疫苗的信息。这些发现共同表明,这些亚人群的决策过程和信息环境存在明显差异,任何在线疫苗接种活动在试图向所有三个亚人群提供准确的疫苗信息时都需要考虑这些差异。
Understanding the rationales and information environments for early, late, and nonadopters of the COVID-19 vaccine
Anti-vaccine sentiment during the COVID-19 pandemic grew at an alarming rate, leaving much to understand about the relationship between people’s vaccination status and the information they were exposed to. This study investigated the relationship between vaccine behavior, decision rationales, and information exposure on social media over time. Using a cohort study that consisted of a nationally representative survey of American adults, three subpopulations (early adopters, late adopters, and nonadopters) were analyzed through a combination of statistical analysis, network analysis, and semi-supervised topic modeling. The main reasons Americans reported choosing to get vaccinated were safety and health. However, work requirements and travel were more important for late adopters than early adopters (95% CI on OR of [0.121, 0.453]). While late adopters’ and nonadopters’ primary reason for not getting vaccinated was it being too early, late adopters also mentioned safety issues more often and nonadopters mentioned government distrust (95% CI on OR of [0.125, 0.763]). Among those who shared Twitter/X accounts, early adopters and nonadopters followed a larger fraction of highly partisan political accounts compared to late adopters, and late adopters were exposed to more neutral and pro-vaccine messaging than nonadopters. Together, these findings suggest that the decision-making process and the information environments of these subpopulations have notable differences, and any online vaccination campaigns need to consider these differences when attempting to provide accurate vaccine information to all three subpopulations.
