Vaccine Delivery Phases

Saskatchewan residents six months and older are eligible to be vaccinated against COVID-19.

• For residents 12 years and older, a primary vaccination series is two doses of Pfizer, Moderna or Novavax (AstraZeneca is no longer available).
• For residents 18 years and older, a primary vaccination can also include a single-dose Janssen vaccination.
• For residents five to 11 years of age, a primary vaccination series is two doses of Pfizer or Moderna.
• A primary vaccination for children younger than five years old is a three-dose Pfizer series or a two-dose Moderna series (pending availability).

It takes up to 14 days to build immunity following the primary vaccination series.

Everyone five years of age and older remains eligible to receive one bivalent booster dose 6 months from their previous dose or previous COVID-19 infection, regardless of the vaccine type and number of doses received previously.

As of March 27, 2023, the following populations are eligible to receive a second COVID-19 bivalent vaccine booster dose 6 or more months from their last COVID-19 bivalent booster dose or SARS-CoV-2 infection (whichever interval is longer as applicable):

• Adults 80 years of age and older.
• All residents 18 years of age and older of long-term care facilities, personal care homes and other congregate living settings (i.e. assisted living settings) providing care for seniors.
• Adults 18 years of age and older who are moderately to severely immunocompromised with medical conditions described in the Canadian Immunization Guide.
• Adults 65-79 years of age, especially if they do not have a known prior history of COVID-19 infection or a positive rapid antigen test or PCR test result.

Bivalent mRNA COVID-19 vaccines contain the original and Omicron strains and are strongly recommended for your booster dose(s). 

Bivalent mRNA COVID-19 vaccines induce stronger and more robust immune responses and provide better protection against the Omicron variants when compared to the original mRNA COVID-19 vaccines.

Children six months to four years of age are not eligible to receive a booster dose at this time.

You are considered up-to-date on your vaccinations if you have received the last dose you are eligible for.

Future epidemiology, data on waning immunity, emerging variants and/or new vaccines will determine future booster dose recommendations from the Ministry of Health.
