COVID-19 — Montreal and its northern suburb Laval, Que., — have among the lowest vaccination rates in the province, according to data from Quebec’s public health institute.Experts say those lower rates aren’t surprising: vaccine hesitancy, low trust in government and negative experiences with the health system are all factors that help explain why people in some communities haven’t been as eager as others to get a shot.“It makes sense that we see under-vaccination in these places,” said Laurence Monnais, a medical historian at Université de Montréal who has studied vaccine hesitancy.Only four of the province’s 18 regions have vaccination rates below 60 per cent, according to recent data by Institut national de santé publique du Québec..
