Learn about temporary medical deferrals for COVID-19 vaccines

What's a COVID-19 vaccine medical deferral?

A COVID-19 vaccine medical deferral is a temporary vaccination credential for Yukon residents who cannot be vaccinated due to a valid medical reason. Medical deferrals are not permanent exemptions from vaccination requirements. All medical deferrals issued by the Government of Yukon have an expiration date. We do not currently issue permanent exemptions.

You can use a COVID-19 vaccine medical deferral to enter establishments and services that require proof of vaccination in the Yukon. We do not recommend relying on COVID-19 vaccine medical deferrals to travel as other jurisdictions may not recognize the Yukon’s medical deferrals.


The following conditions may qualify you for a COVID-19 vaccine medical deferral:

  • You have a history of an anaphylactic reaction to components of both mRNA and adenovirus vector vaccine, such as polyethylene glycol and polysorbate 80, confirmed by a qualified allergist who offers testing and graded dose administrative procedures.
  • You've received anti SARS-CoV-2 monoclonal antibodies or convalescent plasma to treat or prevent COVID-19, except tocilizumab or sarilumab.
  • You've been diagnosed with multisystem inflammatory syndrome.
  • A physician has diagnosed you with myocarditis or pericarditis following your 1st dose with no other cause identified.
  • You had a serious adverse event following your 1st dose of vaccine and are waiting for the Yukon Immunization Program's recommendation on whether you should have a further vaccination. Serious adverse events following immunization (AEFI) are those that required urgent medical care or resulted in hospitalization or permanent disability.

Getting a COVID-19 vaccine medical deferral

To request a COVID-19 vaccine medical deferral:

  1. Check the list of conditions above to see if you could be eligible.
  2. Book an appointment with a physician, nurse practitioner or health care nurse in a rural community.
  3. At your appointment, discuss your need for a COVID-19 medical deferral.
  4. If the health care professional decides that you qualify for a medical deferral, they'll fill out the COVID-19 Vaccine Temporary Medical Deferral form.
  5. The health care professional will submit the form to the Government of Yukon by fax at 867-393-4357.
  6. The Government of Yukon will decide whether to issue a medical deferral within 1 to 3 business days. If we approve your deferral, someone will let you know by telephone. We'll add your deferral record to the proof of vaccination service.
  7. You'll be able to access your medical deferral credential on the proof of vaccination service within 1 to 3 business days after we've approved it.

Using your COVID-19 medical deferral credential

Within the Yukon you can use your COVID-19 vaccine medical deferral credential to access any of the designated establishments and services that require proof of vaccination in the Yukon.


We do not recommend travelling within Canada or internationally with your Yukon COVID-19 vaccine medical deferral credential. There is no federal standard for COVID-19 vaccine medical deferrals. This means that other jurisdictions may not recognize a Yukon medical deferral.

When the federal government creates a standard, you’ll need to get a new deferral credential through the online proof of vaccination service.

Vaccination verifier apps

The Yukon Vaccination Verifier app can scan Yukon COVID-19 vaccine medical deferral credentials. If it's valid, it'll show as “Meets requirements".  

Other provinces and territories cannot scan a COVID-19 vaccine medical deferral credential issued in the Yukon. This may change when the federal government develops a standard. It will not show your medical condition. 


When someone's verifying the COVID-19 vaccine medical deferral, they will not be able to view your medical condition.

Within the QR code, there's a code for the type of medical condition. However, it will not show the specific medical condition when someone scans your QR code with the Yukon Vaccine Verifier app.

We’ve designed the proof of vaccination credential and app to protect your privacy.

  • The app does not store any data from the proof of vaccination credential.
  • The QR code only contains the minimum amount of information to verify your COVID-19 vaccination status.
  • The proof of vaccination credential does not link to any other records.

For more information, read the app privacy policy.
