Although the influenza vaccine is widely recognized as an effective preventive measure, influenza vaccination rates among U.S. adults remain low. Moreover, influenza-related respiratory illnesses may increase the risk of adverse outcomes of COVID-19. Thus, this study examines the mechanisms involved in influenza vaccination uptake. Specifically, this study investigates how health information sources are associated with perceived vaccine efficacy and safety, which, in turn, associated with influenza vaccine uptake. Analyzing cross-sectional survey data from a national U.S. adult sample ( = 19,420), mediation analyses were conducted. Results revealed that considering vaccine efficacy, health information seekers who assigned more value to medical professionals, medical journals, and newspaper articles were more likely to perceive a vaccine as effective, thus being more likely to receive the influenza vaccine. By contrast, individuals who placed more value in social media were less likely to perceive vaccine efficacy, and, in turn, were less likely to get the influenza vaccine. Turning to vaccine safety, the value ascribed to medical professionals was positively associated with vaccine safety, which, in turn, related to influenza vaccine uptake. By contrast, social media, family or friends, and promotions were negatively associated with vaccine safety, and then influenza vaccine uptake.
虽然流感疫苗被广泛认为是一种有效的预防措施，但美国成年人的流感疫苗接种率仍然很低。此外，与流感相关的呼吸道疾病可能会增加 COVID-19 不良后果的风险。因此，本研究探讨了流感疫苗接种的相关机制。具体来说，本研究调查了健康信息来源如何与疫苗的有效性和安全性感知相关，而这些感知又与流感疫苗接种相关。本研究分析了来自美国全国性成年人样本（n=19420）的横断面调查数据，采用了中介分析。结果表明，在考虑疫苗效果方面，将更多价值赋予医疗专业人员、医学期刊和报纸文章的寻求健康信息者，更有可能认为疫苗有效，因此更有可能接种流感疫苗。相比之下，将更多价值赋予社交媒体的个体，不太可能认为疫苗有效，因此不太可能接种流感疫苗。转向疫苗安全性，赋予医疗专业人员的价值与疫苗安全性呈正相关，而疫苗安全性又与流感疫苗接种相关。相比之下，社交媒体、家庭或朋友以及促销活动与疫苗安全性呈负相关，进而与流感疫苗接种相关。
