Babies are born with a certain amount of natural protection against disease, which comes in the form of antibodies they get from their mothers. However, the natural protection does not last past the first year of life and young children are at risk for a number of diseases that can be serious, and even fatal. Fortunately, parents in Canada have free access to vaccines that can immunize their children against such diseases as polio, measles, mumps, and whooping cough.

Childhood immunization helps the immune system build up resistance to disease. It works by giving children vaccines containing tiny amounts of viruses or bacteria that are dead, weakened, or purified components. The vaccines prompt the child’s immune system to produce antibodies that will attack the virus or bacteria to prevent disease. The child’s immune system stores the information about how to produce those particular antibodies, and responds if the child is exposed to that same virus or bacteria in the future.

In Canada, vaccines to prevent the following diseases are considered routine, and are given free of charge to children in all provinces and territories:

• diphtheria;
• tetanus (lockjaw);
• pertussis (whooping cough);
• polio;
• rubella (German measles);
• measles (red measles);
• mumps;
• hepatitis B; and
• Haemophilus influenza type b disease.

These vaccines are given by needle “shots.” In Canada, the hepatitis B vaccine is given alone. The other vaccines are given in combination, according to specific schedules that usually start when your baby is two months old. If you have young children, you should check with your doctor or public health nurse to make sure they are getting the right shots at the right time.

There are also vaccines to protect against varicella (chickenpox), influenza, and some forms of meningitis, but these are not given on a routine basis across Canada. Talk to your health care provider to find out if these shots are right for your child. If your family is planning to travel outside of Canada, you should also make sure that everyone’s shots are up to date.

Many youngsters have some swelling or tenderness at the spot where the vaccine is injected, and some may also develop a mild fever, but these reactions are minor and temporary. Serious side effects such as severe allergic reactions can occur, but are extremely rare, and occur in Canada less often than once per million doses of vaccine.

On the other hand, the diseases that vaccines fight pose serious threats. Diseases such as polio, diphtheria, measles, and whooping cough can lead to paralysis, pneumonia, choking, brain damage, heart problems, and even death in children who are not protected. Because of vaccines, these diseases are no longer common in Canada. However, it is still important to immunize your child for the following reasons:

• When immunization rates drop, these diseases come back. For example, a drop in pertussis (whooping cough) vaccinations in Britain in 1974 was followed by a whooping cough epidemic that killed 36 people in 1978.
• Diseases do not stop at borders. People can carry vaccine-preventable diseases into Canada and spread them to children who are not vaccinated.
• To protect others. Some people can’t have vaccines because of allergies or other reasons. An unvaccinated child with a vaccine-preventable disease is a threat to these people.
