On September 16, 2021, Health Canada granted full approval (Notice of Compliance or NOC) for COMIRNATY™. The vaccine was initially authorized for use in Canada under an Interim Order Authorization on December 9, 2020 under the name Pfizer-BioNTech COVID-19 Vaccine.

COMIRNATY™ and the Pfizer-BioNTech COVID-19 Vaccine have the same formulation, and are considered interchangeable by Health Canada. For additional information, please refer to the Health Canada approved Product Monograph for COMIRNATY™ (available here).

Although the vaccine’s brand name is now COMIRNATY™, Canada will continue to receive vials of the vaccine labeled as Pfizer-BioNTech COVID-19 Vaccine and a transition to new labeling in Canada with the COMIRNATY™ name will occur at a later date. This approval has no impact on any vials of the Pfizer-BioNTech COVID-19 Vaccine currently in Canada and these are usable until their expiry date. As a reminder, vials of Pfizer-BioNTech COVID-19 Vaccine with an expiry date of August 2021 through February 2022 printed on the label may remain in use for 3 months beyond the printed date as long as all approved storage conditions have been maintained.
