Immunization is the process of protecting you from serious diseases, most often through vaccination. Vaccines help your body build immunity safely and effectively, reducing your risk of illness and complications.
Immunization is important in all stages of life. Infants and young children are particularly susceptible to vaccine preventable diseases because their immune systems are less able to fight infection; as a result, they require timely immunization. Older children and adults also require immunization to restore waning immunity and to build new immunity against diseases that are more common in adults.

Getting vaccinated is one of the most important and cost-effective public health interventions. In Canada, vaccines have helped control or eliminate many dangerous infectious diseases. Without vaccination, these infections could return and cause widespread outbreaks. Some diseases (e.g., measles and polio) have no specific cure and can lead to serious complications.
Vaccines don’t just protect you; they help protect those around you too.
When most people in a community are vaccinated against a disease:
it greatly decreases the chances of that disease spreading in the community
it protects babies who are too young to get vaccinated
it protects people who cannot get vaccinated because of medical reasons
Community protection is especially important for those who are most vulnerable.
