Ontario reports new daily COVID-19 record as new measures take effect in Saskatchewan
Ontario hit a record Thursday for new daily COVID-19 cases as hospitals urged a month-long lockdown, while tougher restrictions took effect in Saskatchewan, Alberta recorded its highest death toll and a vaccine maker said vials may yield more doses than expected.
Priority groups such as health-care workers and seniors began receiving Canada’s first doses of the Pfizer-BioNTech vaccine this week.
“The amount of any excess vaccine left in the vial can vary based on provider technique and ancillary supplies,” Pfizer Canada spokeswoman Christina Antoniou said in an email.
“There may be excess vaccine in the vial after withdrawal of five doses, which in some cases may leave enough volume for an additional dose.”
