Canada is suspending use of the AstraZeneca coronavirus vaccine for people under 55 due to concerns that the shot could cause blood clots, ABC News reports.
Why it matters: AstraZeneca's COVID-19 vaccine has been put on hold throughout parts of Europe and has not yet received its emergency use authorization in the U.S. Canada is also facing a relatively slow vaccine rollout, with just 1.8% of its population being fully vaccinated, Bloomberg News notes.
