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.

It is recommended that residents five years and older receive a booster dose, four months after completing their primary series or since their last booster dose. This is regardless of how many doses they previously received.

Bivalent mRNA COVID-19 vaccines contain the original and Omicron strains and are strongly recommended for your booster dose. Currently, mRNA bivalent vaccines are available for booster doses for residents five years and older.  

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

• Individuals five years and older who chose to get an original COVID-19 vaccine for their booster instead of a bivalent vaccine are not required to return to receive a bivalent dose later on.
• 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 completed a primary series and received a booster dose.

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