Canada to require all arriving air passengers to show negative COVID-19 testDr. Maria Sundaram, a Toronto-based epidemiologist at health-care research agency ICES, said given the high rates of community transmission and the high risk of exposure in long-term care homes, catching COVID once vaccinated “is unfortunately almost a given at this point.”“This is not an indication that the vaccine doesn’t work,” she said in an interview Thursday. “This is an indication of the vaccine trying to work in sub-optimal conditions and it’s in a group that hasn’t been fully vaccinated.”Quebec exceeded the 200,000 COVID-19 case mark Thursday after officials reported a record 2,819 new infections.
