Canada’s largest province, Ontario, on Tuesday announced that they would stop offering first doses of the Covid-19 vaccine developed by AstraZeneca-University of Oxford citing evidence that the risk of rare blood clots is higher than previously estimated.
Ontario’s chief medical officer for health Dr David Williams said the decision was made out of an abundance of caution because of increased instances of the rare blood clotting disorder linked to the shot.
