Canada: vaccine rollout raises questions on what it can do for poorer nations

For months Canada was trailing the US in vaccinations but now nearly 47% of the population is covered by one dose

Canada is poised to overtake the US in the proportion of population with one dose of the coronavirus vaccine, following early delays in its rollout. But Canada's success in quickly vaccinating residents has raised questions over what more it can be doing as the pandemic persists in poorer nations.

For months, Canada has trailed its neighbour in vaccination rates, prompting envy and frustration among residents. In March, the US was vaccinating at a rate three times that of Canada.
