Program Information

Vaccines (also called immunizations) create immunity in our bodies to protect us from infectious diseases. There is a long list of diseases that can be prevented with vaccination. The Vaccine Preventable Disease (VPD) program at the Thunder Bay District Health Unit provides immunization services within the District of Thunder Bay to reduce the risk of getting these diseases. 

Due to an increase in requests for appointments at Health Unit immunization clinics, the Health Unit will now prioritize clients who are not attached to a health care provider. Those with a health care provider will be asked to contact their provider for an appointment. This change is necessary to ensure that those clients with no other options have access to immunization services.

The Health Unit provides the following immunization services:

  •  Providing weekly immunization clinics for adults and children
  •  Providing immunization clinics in schools across the Thunder Bay District
  •  Providing annual community flu vaccine clinics across the Thunder Bay District
  •  Providing counselling and immunization services through the TBDHU Travel Clinic for those travelling outside of Canada
  •  Assessing the immunization records of children to make sure they are meeting the requirements of the Child Care and Early Years Act and the Immunization of School Pupils Act
  •  Working with health care providers to ensure the proper storage and distribution of provincially funded vaccines

Get Your Flu Shot!

Influenza or “the flu” is a serious infection that can lead to serious medical conditions and even death. Since it is a virus, the best way to fight the flu is to not get it in the first place. Yearly vaccinations help reduce your risk of getting the flu. Please visit for more information including free vaccination schedules.
