Together with researchers from Copenhagen, Switzerland and the USA, among others, they have examined 8,286 Swedes' attitudes to monetary compensation for taking the vaccine.

- We discovered, somewhat surprisingly, that the vaccination rate rose for everyone, regardless of gender, age and level of education.

The results also show that the incentives increase vaccine intake even in countries with relatively high vaccination levels such as Sweden, says Erik Wengström.

Four percentage points

The participants in the study were selected through an online panel with a representative sample when it comes to gender, age and where you live.

All groups were encouraged to get vaccinated and were given information on how to proceed.

- After 30 days, we checked with the national vaccination register and could see that there was a four percentage point higher vaccination rate among those who were offered a payment of SEK 200, says Erik Wengström.

Experiments with financial incentives for vaccination have been made around the world.

- It has mostly been rolled out and that is a bit of a problem, they have lacked a control group and have not been able to say with certainty that there is any effect.

This is the first study done in a controlled manner.

"A profit for society"

SVT Nyheter has talked to several Malmö residents to find out what they think about the possibility of receiving financial compensation for vaccination.

- From society's point of view, I can see the benefits of doing so because we must have a high vaccination rate among the population, then you can discuss ethical aspects, says Åke Svensson.

Malmö resident Stina Bengtsson does not believe that financial incentives are the solution to increase the vaccination rate.

- It feels more desirable to try to get an increased vaccination rate in a different way, with knowledge dissemination and so on, she says.
