Prime Minister Justin Trudeau said Saturday that Canada’s approach to reopening its economy from the coronavirus shutdown would be “cautious” and not depend on the development of widespread immunity in the population. “I don’t think there are any of the plans that hinge on certain people or individuals being immune or having immunity to COVID-19,” he said at a daily news briefing. The World Health Organization (WHO) warned Saturday that there was no proof that people who survive infection by COVID-19 gain immunity to the disease.
