Health Canada is holding the 300,000 Johnson & Johnson COVID vaccines they have received due to a possible quality control issue.

On Friday, Health Canada said in a statement that the vaccine doses are being held for further review after it was learned they were produced in the same facility which had an error last month that led to millions of Johnson & Johnson doses being ruined.

The vaccines will be reviewed before they are distributed to the provinces to administer to their residents. No timeline has been given as to when the new shots will be administered.

Saskatchewan was set to receive 9,300 doses of Johnson and Johnson vaccine on Tuesday.
