Based on the October 22, 2021, recommendation of the National Advisory Committee on Immunization, a traveller may qualify for a temporary exception due to medical inability to be vaccinated in order to travel within or depart Canada if they have:
- Certified medical contraindications to full vaccination against COVID-19 with an mRNA vaccine:
- A history of anaphylaxis after previous administration of an mRNA COVID-19 vaccine (and noting that most people who experienced a severe immediate allergic reaction after a first dose of an mRNA COVID-19 vaccine can safely receive future doses of the same or another mRNA COVID-19 vaccine after consulting with an allergist or another appropriate physician); and/or
- A confirmed allergy to polyethylene glycol (PEG), which is found in the Pfizer BioNTech and Moderna COVID-19 vaccines (note that if a person is allergic to tromethamine which is found in Moderna, they can receive the Pfizer-BioNTech product).
- Medical reasons for delay of full vaccination against COVID-19: A history of myocarditis/pericarditis following the first dose of an mRNA vaccine; and/or
- An immunocompromising condition or medication that requires waiting to vaccinate when immune response can be maximized (i.e., waiting to vaccinate when immunocompromised state or medication is lower).
- A medical condition precluding full vaccination against COVID-19 (not covered above), as briefly described by the medical physician or nurse practitioner.
