在公共卫生危机的过程中,对疫苗接种的态度如何变化?我们报告了在COVID-19大流行的六个月(2020年3月16日至8月16日)内对美国居民进行的纵向调查结果。过去的研究表明,疾病威胁的显著性增加应该改善对疫苗的态度,与此相反,我们观察到当COVID-19疫苗变得可用时,获得疫苗的意图减少。我们进一步发现,普遍的疫苗态度和接种流感疫苗的意愿有所下降。异质性分析表明,这种下降是由认同为共和党人的参与者推动的,他们在疫苗态度和意图方面表现出负面趋势,而民主党人基本保持稳定。与对风险认知和行为的研究一致,那些对COVID-19疫苗接种持不太赞成态度的人也认为该病毒的威胁较小。我们提供了暗示性的证据表明,对媒体渠道和社交网络的不同接触可以解释自我认同的民主党人和共和党人之间观察到的不对称极化。
How do attitudes toward vaccination change over the course of a public health crisis? We report results from a longitudinal survey of United States residents during six months (March 16 –August 16, 2020) of the COVID-19 pandemic. Contrary to past research suggesting that the increased salience of a disease threat should improve attitudes toward vaccines, we observed a decrease in intentions of getting a COVID-19 vaccine when one becomes available. We further found a decline in general vaccine attitudes and intentions of getting the influenza vaccine. Analyses of heterogeneity indicated that this decline is driven by participants who identify as Republicans, who showed a negative trend in vaccine attitudes and intentions, whereas Democrats remained largely stable. Consistent with research on risk perception and behavior, those with less favorable attitudes toward a COVID-19 vaccination also perceived the virus to be less threatening. We provide suggestive evidence that differential exposure to media channels and social networks could explain the observed asymmetric polarization between self-identified Democrats and Republicans.
