COVID-19: Quebec to lift state of emergency when kids are vaccinated, Legault says Dubé, one of the researchers who conducted the survey, said she believes the risk-benefit calculation is different for parents of young children, because children are less likely to develop severe cases of COVID-19.“When we asked parents with low or no intention to vaccinate, the two main reasons are really: I don’t believe vaccines are needed because my child is not at risk and vaccine safety concerns,” Dubé said.Support among parents for the vaccination of children aged 12 to 17 rose during the course of the vaccination campaign, and Dubé said she expects that to happen among parents of younger children.
