TORONTO --
Canada welcomed the newest vaccine to its supply chain earlier this week with the arrival of the single-dose Johnson & Johnson vaccines, but quality concerns have halted its distribution across the country for now.
The only single-dose vaccine approved for use in Canada has been hailed by experts as a key to getting people in remote locations vaccinated, and as an important tool in turning the tide of the third wave of COVID-19 across the country.
The vaccines were set to be distributed to provinces next week.
In a statement, Health Canada stated it âlearned that a drug substance produced at the Emergent site (in Baltimore) was used in the manufacturing of the initial Janssen vaccinesâ slated for use in Canada.
