用金钱作为公众接种疫苗的动机是有争议的，在研究中的结果好坏参半，其中很少有随机试验。为了测试金钱作为获得疫苗的激励措施的效果，Campos-Mercade等人于2021年在瑞典开展了一项研究，当时不同年龄组首次有资格接受严重急性呼吸道冠状病毒2型疫苗（见Jecker的观点）。一个小的现金奖励的效果，大约24美元，与几个行为推动的效果进行了比较。这项预先注册的随机临床试验的结果是，金钱有能力将参与率提高约4个百分点。轻推和提醒似乎没有害处，甚至有一个小的积极影响。当然，像这样付钱让人接种疫苗是否道德的问题需要解决。-CA在瑞典，24美元的货币奖励将疫苗接种率从约72%提高到约76%。COVID-19疫苗接种率的停滞威胁到公共卫生。为了提高疫苗接种率，世界各国政府正在考虑使用货币激励措施。在此，我们提供了有关保证支付对COVID-19疫苗接种率影响的证据。我们在瑞典进行了一项大型的预先注册的随机对照试验（有8286名参与者），并将数据与全民接种记录联系起来。我们发现，24美元（200瑞典克朗）的适度货币支付使疫苗接种率从基线率71.6%提高了4.2个百分点（P = 0.005）。相比之下，行为轻推增加了接种疫苗的意向，但对疫苗接种率的影响很小，在统计学上也不显着。研究结果强调了适度的货币激励措施在提高疫苗接种率方面的潜力。
Using money as a motivation for the public to get vaccinated is controversial and has had mixed results in studies, few of which have been randomized trials. To test the effect of money as an incentive to obtain a vaccine, Campos-Mercade et al. set up a study in Sweden in 2021, when various age groups were first made eligible to receive the severe acute respiratory coronavirus 2 vaccine (see the Perspective by Jecker). The effect of a small cash reward, around US $24, was compared with the effect of several behavioral nudges. The outcome of this preregistered, randomized clinical trial was that money had the power to increase participation by about 4 percentage points. Nudging and reminding didn’t seem to be deleterious and even had a small positive effect. Of course, the question of whether it is ethical to pay people to be vaccinated like this needs to be addressed. —CA In Sweden, monetary incentives of US $24 increased vaccination rates from approximately 72% to approximately 76%. The stalling of COVID-19 vaccination rates threatens public health. To increase vaccination rates, governments across the world are considering the use of monetary incentives. Here we present evidence about the effect of guaranteed payments on COVID-19 vaccination uptake. We ran a large preregistered randomized controlled trial (with 8286 participants) in Sweden and linked the data to population-wide administrative vaccination records. We found that modest monetary payments of 24 US dollars (200 Swedish kronor) increased vaccination rates by 4.2 percentage points (P = 0.005), from a baseline rate of 71.6%. By contrast, behavioral nudges increased stated intentions to become vaccinated but had only small and not statistically significant impacts on vaccination rates. The results highlight the potential of modest monetary incentives to raise vaccination rates.
