COVID-19 Spring Booster Recommendations

March 23, 2023 |

Manitoba Public Health has released eligibility criteria for spring COVID-19 booster doses based on the National Advisory Committee on Immunization (NACI). View the most recent NACI guidance here.

Manitoba Health specifically recommends those at highest risk to receive a COVID-19 booster this Spring:

  • Adults age 65 and older.
  • Indigenous peoples age 45 and older, including First Nations, Inuit, and Métis peoples, regardless of their place of residence.
  • Residents of long-term care, assisted living, or supportive housing facilities.
  • Adults age 18 and older who are moderate to severely immunocompromised.

It is recommended to wait at least six months between COVID-19 booster doses. People should also wait six months between a COVID-19 infection and receiving any booster dose.

Pending NACI recommendations, a fall 2023 COVID-19 booster program may be offered. It is recommended that you clearly communicate with patients how the timing of a spring booster dose may affect eligibility for a fall booster dose.


Manitoba Health recommends bivalent vaccines. Monovalent booster doses may be offered if an individual chooses not to receive a bivalent booster and a monovalent booster dose is available.
