The Thunder Bay District Health Unit will prioritize providing the following immunization services (as of October 4, 2021):

  • Routine infant vaccines for those 2-18 months of age without a health care provider.
  • Routine vaccines for school-aged children without a health care provider.
    • Grade 7 students will receive their vaccines at school during the 2021-2022 school year. Students in Grade 8 who missed their vaccines due to pandemic restrictions will be offered vaccines at school. They can also visit their health care provider. Those without a health care provider can book an appointment at the TBDHU clinic. Those living in a district community should contact the nearest TBDHU branch office.
  • Flu (influenza) vaccine for children 6 months to 23 months. Pharmacies are now able to provide flu vaccine to children 2 years of age and older.
    • Flu shot clinic dates will be added to the Getting a Flu Shot page as soon as they are available; please check back regularly. Children 6 months to 4 years and those over 6 years with specific medical conditions will be considered a priority in October due to the high risk of flu-related complications or are more likely to require hospitalization if they are sick with the flu.
  • Immunocompromised individuals without a health care provider requiring routine vaccines.

Thunder Bay - Appointments are required to provide a safe environment for clients and staff. Walk-in services will not be available. Please call us at 625-5900 to book an appointment.

District Communities - Contact your primary care provider. TBDHU branch office staff will be offering immunizations at school; check the School Immunization page for details and dates. 

We will continue to accept reports of vaccines administered and provide all publicly funded vaccines to primary care providers in Thunder Bay.
