Canada's chief medical officer of health Dr. Theresa Tam reacted Saturday to recent comments by Quebec Premier François Legault that letting a large number of non-vulnerable people to get COVID-19 naturally would be the best defence against a second wave. She said while the virus can have a "devastating" impact on vulnerable people, it still can result in "severe" outcomes for the young and the rest of the population and the idea of generating natural immunity is "not a concept that should be supported" or undertaken.
