Why has Canada's COVID-19 vaccine rate slipped globally?

As of Sunday, Canada had fallen to 27th in the world in vaccines administered, behind the U.S., the U.K. and smaller countries like Poland and Serbia, according to data aggregated by the University of Oxford. Canada was one of the first countries in the world to approve the Pfizer-BioNTech and Moderna vaccines for use and have reserved record doses per person — but the country is facing significant shipment delays. There are also growing questions about whether the vaccine contracts signed by the federal government are in the country's best interest, but Prime Minister Justin Trudeau assures the public that Canada is on track to meet its vaccination goals. Today on Front Burner, CBC News senior writer J.P. Tasker discusses why Canada is falling behind and what might be done about it.
