Abstract
We analyze the effects of a vaccination program providing free flu vaccine to individuals aged 65 or more on take-up behavior and hospitalization. Using both administrative and survey data, we implement a regression discontinuity design around the threshold at age 65, and find that the effect of the program on take-up ranges between 70% and 90% of the average vaccination rate for individuals aged less than 65. We show that this effect is not entirely driven by an income channel, but also depends on the expected benefits of vaccination. The results on health outcomes provide suggestive evidence that the program reduces the likelihood of emergency hospitalization.
摘要
我们分析了一项为65岁及以上人群提供免费流感疫苗的疫苗接种计划对疫苗接种行为和住院情况的影响。利用行政数据和调查数据，我们围绕65岁这一阈值实施了回归断点设计，发现该计划对疫苗接种的影响范围在65岁以下人群平均接种率的70%至90%之间。我们表明，这种影响并非完全由收入渠道驱动，还取决于疫苗接种的预期收益。关于健康结果的研究结果提供了暗示性证据，表明该计划降低了紧急住院的可能性。
