What is it?

There are many different vaccines that protect against diphtheria, pertussis, tetanus, polio and Haemophilus influenza B diseases (for more information on diphtheria, pertussis, tetanus, polio and Haemophilus influenza B diseases see Facts About for each disease). Your healthcare provider (i.e., doctor, nurse practitioner, etc.) will decide which vaccine is best to give based on the Ontario Immunization schedule.

DPTP-Hib (e.g., Pediacel®):

DPTP (e.g.,Infanrix®-IPV):

Tdap-IPV (e.g., Adacel®-IPV, Boostrix®-IPV):

Hib (e.g., Act-Hib™):

Polio (e.g., IPV):


All children in Ontario are required by law to be vaccinated against tetanus, diphtheria, polio and pertussis.

For people who become ill, vaccination usually results in milder illness than those who are not immunized.

Who should receive the vaccines?

If immunizations have been given outside of the Ontario immunization schedule, your health care provider can assist in deciding a “catch-up” schedule if needed.

The following groups should discuss the benefits and potential risks of the vaccines with a doctor before vaccination:

Are there side effects from the vaccine?

The most common side effects of the vaccines are:

If necessary, a cold, wet compress to the site and/or using acetaminophen can help to prevent or relieve pain, swelling and/or fever after vaccination. The benefits of protection against disease significantly outweigh any risk from the vaccine.

Severe allergic reactions after vaccination are rare and may not be caused by the vaccine.

If you think you are having a serious reaction seek medical attention right away. Serious reactions and any changes in your health or your child’s health after vaccination should be reported as soon as possible to your health care provider and the Health Department.

Who should NOT get the vaccine?

Don’t forget to update your record of protection.

After you or your child receives a vaccination, update your yellow vaccination record. For children in school or daycare, please call the Health Department to update your child’s immunization records. Keep your records in a safe place!
