Immunization is one of the most important advances in public health. Experts believe
it has saved the lives of more Canadians over the past 50 years than any other health
Before vaccines became available, many Canadian children died from diseases like
diphtheria, measles, and polio. These diseases can now be prevented by immunization.
Immunization protects individuals who receive vaccines. It also helps to prevent
the spread of infection in the community which ultimately protects:
- • infants who are too young to be vaccinated,
- • people who cannot be vaccinated for medical reasons (e.g. some people with weakened
immune systems cannot receive some vaccines),
- • people who may not get full protection from immunization (e.g. the elderly).
Here is an example of how vaccines have protected Canadians against Pertussis:
The first vaccine against Pertussis was introduced in 1942. Between 1938 and 1942,
when the vaccine was introduced, about 1.5 Canadians in a thousand got sick with
Pertussis. In the worst year of that 5 year period, about 20,000 Canadians got sick.
Between 2007 and 2011, about 4 Canadians in 10,000 got sick with Pertussis. In the
worst year of that five year period, 1961 Canadians got sick.
