COVID-19 Vaccine Information for Patients

All cancer patients should get a COVID-19 vaccine.

- Any of the available COVID-19 vaccines can be used for cancer patients. 
- Although vaccine efficacy may be less in those on active treatment, don’t delay — any protection is better than none.
- Time vaccination for a few days prior to chemotherapy cycles to maximize chance of response.
- Patients on prednisone or equivalent ≥ 20 mg/day may be too immunosuppressed to respond to vaccination.

The Saskatchewan Ministry of Health and the Saskatchewan Health Authority are sending letters to individuals who have been identified as members of the clinically extremely vulnerable priority group for phase 2 of Saskatchewan’s Vaccination Delivery Plan. 

This includes cancer patients who meet the criteria as determined by Cancer Agency physicians. Cancer patients who do not meet the criteria are encouraged to book their immunization when their age group becomes eligible.

Please note:

The brand of vaccine available at a vaccination clinic can change at any time, based on availability. All the vaccines are safe and approved by Health Canada and will help to reduce the chance of severe illness and death. You are encouraged to take whatever vaccine is offered when you are eligible.
