最近的证据表明,许多国家对疫苗接种犹豫不决,无法持续遏制 COVID-19。通过对德国 20,500 名在线受访者进行阶乘调查实验,我们评估了三种提高疫苗接种率的策略的有效性,即提供自由、经济报酬和当地医生的疫苗接种。我们的结果表明,所有三种策略都可以将疫苗接种率总体提高约 2 至 3 个百分点 (PP),而在尚未决定的国家中提高 5 个 PP。该组的综合效果可能高达 13 PP。然而,不同年龄组的不同策略的回报各不相同,年龄较大的群体对当地的疫苗接种更敏感,而年轻的群体对接种疫苗的公民的自由度提高最敏感。
Recent evidence suggests that vaccination hesitancy is too high in many countries to sustainably contain COVID-19. Using a factorial survey experiment administered to 20,500 online respondents in Germany, we assess the effectiveness of three strategies to increase vaccine uptake, namely, providing freedoms, financial remuneration, and vaccination at local doctors. Our results suggest that all three strategies can increase vaccination uptake on the order of two to three percentage points (PP) overall and five PP among the undecided. The combined effects could be as high as 13 PP for this group. The returns from different strategies vary across age groups, however, with older cohorts more responsive to local access and younger cohorts most responsive to enhanced freedoms for vaccinated citizens.
