A growing number of Canadian parents say they are opposed to vaccinating their children, according to a new poll, amid a resurgence in potentially deadly diseases such as measles.

The opinion poll, released Wednesday by the Angus Reid Institute, comes as public health officials try to catch up on routine vaccinations among children after a drop off during the pandemic. 

Among survey respondents, 17 per cent of parents of minors said they are “really against” vaccinating their kids, compared with four per cent in 2019. A majority, 67 per cent, said they would vaccinate their child “without reservation,” down from five years prior.
