COVID-19 Vaccines


The Health Unit will start receiving its supply of Moderna XBB vaccine the week of September 25. Those at highest risk (such as residents of long-term care homes) will receive the vaccine first. Other priority groups will be eligible for XBB vaccines throughout October as supply increases.

The TBDHU Community Vaccine Clinic at the CLE will reopen on October 3 to provide XBB vaccines to all priority groups in Thunder Bay. Please visit our Vaccine Clinics page for more information about this clinic. This clinic will be BY APPOINTMENT ONLY for the first 2-3 weeks; eligible people can book a COVID-19 vaccine appointment through the online Provincial Booking System

This clinic will only offer the Moderna XBB vaccine at first; we will provide updates once we have received supplies of the Pfizer XBB vaccine.

Most pharmacies and some health care providers will also begin to offer XBB vaccines to priority groups throughout October, depending on vaccine supply.  Pharmacies will not receive the Moderna XBB vaccine; however, they will receive supplies of the Pfizer XBB vaccine. 

Before going in for a vaccine, book an appointment or call ahead to confirm you can get the vaccine you want.

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 your COVID-19 vaccines

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.

  • People aged 6 months and older are considered up to date with their COVID-19 vaccines if they have received a Fall 2023 COVID-19 dose.

It is recommended that the Fall 2023 COVID-19 dose be an XBB vaccine. 

People in certain priority groups are eligible to receive a Fall 2023 COVID-19 vaccine dose first. These priority groups are listed in the “Priority Groups for Fall 2023 COVID-19 Vaccination” section below. 

Starting on October 30, 2023, everyone who lives, works, or studies in Ontario will be eligible for a Fall 2023 COVID-19 dose if they are at least 6 months old, whether previously vaccinated or not.
