Non-Vaccinated Parents might still Vaccinate their Kids: Same Problem, Different Choice.
With a vaccination rate of 1.5 million vaccinations per week, it won’t take long until children below 17 years old can be vaccinated. Last week, the Dutch Health Counsel advised to vaccinate 12-to-17-year old’s with health issues, with the expectation that this advice will soon be extended to healthy children. Countries such as Germany, France and Canada already reached this point -- children from the age of 12 can get a COVID-19 vaccination. China allows children from the age of 3 to get vaccinated against COVID-19. However, it will be the parents that ultimately decide on the vaccination of their children. In that case the choice should be relatively simple, as parents already decided for themselves on whether to get “vaxed.” But is vaccinating yourself truly the same as vaccinating your child?
We investigated the decision to get a vaccination for a hypothetical, relatively unknown and uncertain disease, with comparable features of the COVID-19 virus. The risks of the disease and the (potentially severe) side-effects were proposed to be the same for children and adults. A priori, we expected participant’s preferences to be rational and consistent over time, leading to the same vaccination decision for their child as for themselves. Interestingly, we find that adults are 28% more likely to accept the vaccine for their child, as compared to likelihood of getting vaccinated themselves.
Trying to understand this discrepancy, we find that the underlying levels of expected regret towards making the wrong choice played an important role. We measured two types of regret: 1) the experienced regret when getting the disease without vaccination, and 2) the experienced regret when experiencing the side-effects after vaccination. Figure 1 shows our results: first, people overall experience higher levels of both types of regret when making the choice to vaccinate their child (Panel B) than for themselves (Panel A). Second, most predominately, we see a trend that the experienced regret after getting the disease without vaccination is higher when it pertains your children compared to yourself. Even for people that decided to vaccinate themselves anyway, the regret after getting the disease without vaccination is less (Panel A, blue, y-axis), compared to the same regret when vaccinating their children (Panel B, blue, y-axis).
What do these findings imply? First, fear and regret are important drivers of the decision to get vaccinated. Second, the levels of regret differ when we make the decision for ourselves compared to our children. Apparently, vaccinating yourself or your child are not as perfectly correlated as we would rationally assume. People are more willing to vaccinate their child than themselves, according to our findings. Emphasizing and focusing on the risks and consequences of both the side-effects of the vaccination as well as a COVID-19 infection, specifically for children, could promote an optimal decision process. Our findings are optimistic: even parents that might be willing to take the risk of a COVID-19 infection themselves, seem to be hesitant to take the same risk with their children.
