COVID-19 Vaccine Eligibility

Eligibility for the COVID-19 vaccine is based on an individual’s age and medical conditions. Check below to see which doses you are eligible for, then book a vaccine appointment.  At the time of your appointment, tell your healthcare provider if you are immunocompromised or have a condition that puts you at higher risk of severe outcome for COVID-19; you may need a larger dose of the vaccine.

First and Second Dose Eligibility

The following groups are eligible for a first and second dose:

  • All people aged 6 months of age and older
    • Eligibility will be based on age at the time of appointment. If your child is not at least 6 months of age at the time of the appointment, they will not be able to receive the vaccine. 

When: First and second doses are typically given as a series. There are different time periods you should wait between doses, depending on which vaccine you receive. The below chart outlines recommended timing between the first and second dose for different brands of the vaccine. 

Booster Eligibility

Access to COVID-19 booster doses is currently available territory-wide. You are eligible if:

  • It has been six months since your last dose 
  • It has been at least 3 months since COVID infection 
  • You are 5 years of age or older

Please note; those age 5-11 years of age are only eligible for the original type vaccines at this time, bivalent vaccine products are currently available to residents 12 years of age and older (in line with current Health Canada approval of vaccine product administration).

What are Boosters and what's the difference between 3rd/4th dose and who needs them?

A vaccine booster is recommended because over time, the protection generated from the first two doses may be waning.  

Booster doses increase immunity and are being offered on a voluntary basis, a minimum of six (6) months after your second or third dose of a COVID-19 vaccine. 

A booster contains less vaccine product than an additional full dose.  If you are immunocompromised please tell your healthcare provide at your immunization appointment; you may be eligible for a 3rd full dose instead of a booster. 

A third or fourth full dose of the mRNA COVID-19 vaccines (Pfizer or Moderna) is identical to the first two doses. It is administered to help protect people with weakened immune systems who may not have had a strong enough response to the first two doses of one of the mRNA vaccines.

Am I considered Immunocompromised?

Eligibility for the COVID-19 vaccine is based on an individual’s age and medical conditions. Often booster doses are available earlier to individuals who are immunocompromised.

An individual would be considered to have moderate to severe immune compromise if they have one of the following conditions or treatments:

  • Active treatment of cancer or other hematologic malignancy 
  • Recipient of solid-organ transplant and taking immunosuppressive therapy 
  • Treatment of leukemia with T cell therapy, or had a stem cell transplant within the last two years 
  • Moderate to severe primary B or T cell immunodeficiency (e.g.: Di George Syndrome or Wiskott-Alrich Syndrome) 
  • Stage 3 or advanced untreated HIV infection or diagnosis of Acquired Immune Deficiency Syndrome (AIDS) 
  • Active treatment of active disease (neurological, autoimmune, neoplastic) with any of the following immune suppressive therapies: 
    • Corticosteroids at doses equivalent to or greater than prednisone 20mg/day for greater than 14 days 
    • Anti-B cell therapy (e.g.: rituximab/Rituxan, belimumab/Benlysta, etanercept/Enbrel, tocilizumab/Actemra) 
    • Alkylating agent therapy (e.g.: carboplatin, chlorambucil, cisplatin, cyclophosphamide) 
    • Systemic antimetabolite therapy (e.g.: 6-mercaptopurine, 5-fluorouracil, gemcitabine, cytarabine, pemetrexed, methotrexate) 
    • Tumour necrosis factor (TNF) inhibitor therapy (e.g.: infliximab/Remicade, etanercept/Enbrel, adalimumab/Humira) 
    • Other biologic therapy (e.g.: ustekinumab/Stelara) 

If you believe you have moderate to severe immune compromise and your situation is not represented in this list, talk your healthcare provider about whether your condition makes you eligible for a 3rd or 4th dose of the COVID-19 vaccine.
