Vaccines
A vaccine typically contains an ingredient that resembles a pathogen. This ingredient is often made from weakened or killed forms of a pathogen, its toxins, or one of its surface proteins. These forms are not harmful to your health, but rather helps with immunity.
The immune system is a complex network of cells and proteins that defends the body against infection. There are two common ways to build immunity.
- You can get infected by a virus, bacteria, and other disease-causing microorganism (pathogen)
- You can receive a dose of a vaccine[AL1]
For more information on Childhood Immunization, and when your child should get them please visit the Ministry of Health Ontario.

Frequently Asked Questions:
How does a vaccine work?
When the vaccine enters your body, often through injection, your body will recognize it as the pathogen it came from and trigger an immune response to destroy it. Similarly to building natural immunity, your body will remember what it destroyed and how to destroy it quickly in the future.
The pathogen will cause damage to your body until an immune response can destroy it. You will experience symptoms due to the pathogen (e.g., disease, illness, etc.) and your immune response (e.g., fever, fatigue, etc.). After destroying the pathogen, your immune system keeps a record of it so it can recognise and destroy the pathogen quickly if it enters the body again.
What are the benefits of vaccines?
You can receive the protective benefits/immunity against a pathogen without experiencing the adverse symptoms associated with being infected by that pathogen.
Are vaccines safe?
Yes, the vaccines that Grace Health Centre recommends have all been rigorously tested and studied by reliable, international governments and institutions. Every individual is unique and, thus, some individuals may experience unintentional side effects from vaccines; but, generally, vaccines do more good than harm.
What vaccines should I get?
There are various vaccines that Health Canada recommends Canadians get at specific ages. For information on all of those, and more, visit the government of Canada’s Vaccines and Immunizations website.
