COVID-19 Vaccines


The Health Unit does not currently have a supply of XBB vaccine. We anticipate that XBB vaccines will potentially become available late September/early October, starting with those at highest risk (residents of long-term care homes).
We will provide an update on when and where the public can access this new vaccine as soon as we receive provincial guidance.

Individuals 5 years and older should consider delaying receipt of another COVID-19 vaccine dose until they become eligible under the Fall 2023 COVID-19 Vaccine Campaign. This campaign is expected to start in October 2023 for those at highest risk from COVID-19 (65+, immunocompromised, etc.). See the Dose Information section below for more information. 

In September, TBDHU will offer COVID-19 vaccines by appointment only at its Main Office Clinic. Appointments in the city of Thunder Bay can be made through the Provincial Booking System. The Community Vaccine Clinic will reopen in October. 

For information on how to book in to clinics in District communities, see the District COVID-19 Vaccination Clinics page.


Stay up to date on all COVID-19 vaccine doses

Keeping up to date with COVID-19 vaccines continues to be one of the most effective ways to protect yourself against serious illness, hospitalization, and death from COVID-19, as vaccine protection can decrease over time.

What does staying up to date mean?

  • 6 months – 4 years: Completed a primary vaccine series. Booster doses are not currently recommended for this age group.
  • 5 years and older:
    • Completed a primary series and receipt of the currently recommended booster dose.

Dose information

As of July 2023, all primary and booster doses will be administered using bivalent vaccine products. This page will be updated as product formulations, availability, and recommendations change.
