Public education campaigns are promising methods for promoting vaccine uptake. In April 2021, the U.S. Department of Health and Human Services launched the COVID-19 public education campaign. This study is one of the first evaluations of this COVID-19 public education campaign. We tested associations between channel-specific campaign exposure (i.e. digital, TV, radio, print, and out-of-home advertising) and COVID-19 first-dose vaccinations among a nationally representative online sample of 3,278 adults. The study introduces novel ways to simultaneously evaluate short- and long-term cumulative media dose, filling an important gap in campaign evaluation literature. We observed a positive, statistically significant relationship between the short-term change in digital media dose and the likelihood of first-dose vaccination, and a positive, statistically significant relationship between long-term cumulative TV dose and the likelihood of first-dose vaccination. Results suggest that both digital and TV ads contributed to vaccination, such that digital media was associated with more immediate behavioral changes, whereas TV gradually shifted behaviors over time. As findings varied by media channel, this study suggests that public education campaigns should consider delivering campaign messages across multiple media channels to enhance campaign reach across audiences.
公共教育活动是促进疫苗接种的一种有前途的方法。2021 年 4 月,美国卫生与公众服务部发起了 COVID-19 公共教育活动。本研究是对这一 COVID-19 公共教育活动的首次评估之一。我们在一个由 3278 名成年人组成的全国代表性在线样本中,测试了特定渠道的活动接触(即数字、电视、广播、印刷和户外广告)与 COVID-19 首剂疫苗接种之间的关联。该研究介绍了同时评估短期和长期累积媒体剂量的新方法,填补了活动评估文献中的一个重要空白。我们观察到数字媒体剂量的短期变化与首剂疫苗接种的可能性之间存在正相关且具有统计学意义的关系,长期累积的电视剂量与首剂疫苗接种的可能性之间也存在正相关且具有统计学意义的关系。结果表明,数字和电视广告都有助于接种疫苗,因此数字媒体与更直接的行为变化有关,而电视则随着时间的推移逐渐改变行为。由于媒体渠道的结果不同,本研究表明公共教育活动应该考虑通过多种媒体渠道传递活动信息,以增强受众的活动覆盖面。
