TORONTO, May 13 (Reuters) - The Canadian province of Quebec
will no longer offer first doses of the AstraZeneca
COVID-19 vaccine as of Thursday, but will offer second doses
using current supplies and future deliveries, the province's
health ministry said in a release.
Several provinces made similar announcements on Monday and
Tuesday, with most citing concerns about supply, though the
province of Ontario also indicated that it was concerned about
the risk of rare blood clots.
