Getting
immunized is important for at least two reasons: to
protect yourself and to protect those around you. A successful vaccination
program depends on the co-operation of every person.
Improved sanitation, hygiene, and other living conditions have
created a generally healthier environment and reduced the risks for disease
exposure and infection in Canada. However, the dramatic and long-term decrease
of diseases is primarily a result of widespread immunizations throughout the
Canadian population.
Even though some diseases, such as
polio, rarely affect people in Canada, all of the
recommended childhood immunizations and booster vaccines are still needed.
These diseases still exist in other countries. Travellers can unknowingly bring
these diseases into Canada and infect people who have not been immunized.
Without the protection from immunizations, these diseases could be imported and
could quickly spread through the population, causing epidemics. Non-immunized
people living in healthy conditions are not protected from disease; only
immunizations prepare the immune system to fight the disease organisms.
