论文摘要
我们报告了一项大规模的随机对照试验，旨在评估唐纳德·特朗普（Donald Trump）的亲疫苗信息的党派提示是否会诱使美国人获得Covid-19-19-19。我们的研究涉及在2021年10月向数百万美国YouTube用户提供27秒广告。结果表明，该活动的平均治疗县的疫苗数量增加了103。分布在1,014个经过治疗的县中，该活动的总效应估计增加了104,036疫苗。该活动具有成本效益：总预算约为100,000美元，获得额外疫苗的费用约为1美元以下。
We report a large-scale randomized controlled trial designed to assess whether the partisan cue of a pro-vaccine message from Donald Trump would induce Americans to get COVID-19 vaccines. Our study involved presenting a 27-second advertisement to millions of U.S. YouTube users in October 2021. Results indicate that the campaign increased the number of vaccines in the average treated county by 103. Spread across 1,014 treated counties, the total effect of the campaign was an estimated increase of 104,036 vaccines. The campaign was cost-effective: with an overall budget of about \$100,000, the cost to obtain an additional vaccine was about \$1 or less.
