Childhood Immunization – The Best Protection

How do they work?

To make immunization safer than getting the disease, the bacteria or virus is killed or weakened before being given as a vaccine. The immune system develops antibodies to fight the disease without causing illness. If the person contracts the disease, the body is prepared to fight the disease.

Are they safe?

Yes. Vaccines are very safe. There are rarely reasons not to get vaccinated. Serious problems after needles are rare.

  • If your child had an allergic reaction to a vaccine (such as breathing problems, severe swelling of the throat or mouth), talk to your doctor before the child receives another shot.
  • If your child is very sick when it’s time for a vaccine, talk to your doctor.
  • Common reactions to vaccines
  • Slight fever, mild pain, swelling and redness where the needle was given.
  • Fever, with or without a rash may be seen seven to 10 days after having MMR (measles, mumps, rubella) or Varicella vaccine.
  • Ask your doctor what to give for fever or pain.

Is immunization required for attendance at school or day care in Ontario?

For children attending school in Ontario, a written (or proof of) immunization record is required by law for diphtheria, tetanus, polio, measles, mumps, rubella, varicella and meningococcal disease unless there is a valid, written exemption.

You may decide because of medical, religious or philosophical reasons not to immunize your child. In this case, you will need to provide a valid, written exemption to your local public Health Unit. If the disease appears in your child’s school or day care, your child may have to stay out of school/day care until the disease is no longer present.

Parents/guardians are required to provide this information to their local public Health Unit and to update the information as necessary. You should contact your local public Health Unit or check with your day care centre for the specific immunization requirements

You may need an updated record for:

  • Starting school.
  • Transferring to another school.
  • University or college.
  • Camp.
  • Employment.
  • Emergency health care.
  • Travel.

When their children are immunized parents can call the Health Unit at 519-426-6170 Ext. 3220 or 905-318-6623, or fax the record to 519-426-9974, or report online at hnhu.org’s immunization reporting.
