The original study from Europe is published in the popular journal Science.
According to the data received, a payment of 20 euros increases the number of people wishing to be vaccinated by 4.2%. But the impact of non-monetary incentives does not give the corresponding effect, the number of vaccinations remains at a stable level.
Many European countries have set vaccination coverage targets of 70% or more. Finding incentives has proven to be a daunting task. There is no doubt that a financial solution is the most reliable method, but not all governments are ready for it.
In a large-scale study published in Science magazine, 8300 people took part, the age of which varied in the range of 18-49 years. It was conducted by specialists from universities in the USA, Denmark, Sweden, Switzerland. All participants were divided into 5 groups, but only one was promised a cash reward in the amount of 200 Swedish kronor (approximately 20 euros) for vaccinations during the next month. Another group consisted of people who were not offered anything in exchange for vaccinations. Participants in the other three groups received non-monetary incentives.
The percentage of vaccinated was checked after a month. The number of vaccinees in the first group who were expecting a cash reward increased by 4%, from 72% to 76%. At the same time, neither age, gender, nor income mattered. Other incentives, on the other hand, have proven useless – an initially positive intention to get vaccinated in the short term has not led to a real increase in the number of vaccinations.
Dr. Florian Snyder, a researcher at the University of Basel, says:
“The results provide new insights into fears that monetary rewards could be counterproductive and prevent undecided people from vaccinating, for example, due to poor feeding. On the contrary, even small monetary incentives can have a positive effect on the number of vaccinations. ”
However, researchers note:
Importantly, our findings do not mean that we should pay people. Our research does not address the question of whether it is morally acceptable to pay someone to get vaccinated. However, motivation works …
