Ontario Students To Benefit From New Vaccine

McGuinty Government Adds Meningococcal Vaccine To Voluntary School Immunization Program

Ministry of Health and Long-Term Care

Starting in September, parents will be able to choose to vaccinate their children against four strains of invasive meningococcal disease (IMD).

The Ontario government will be supplying the vaccine, Menactra, to public health units to use in the voluntary school-based immunization program for Grade 7 students.

In the school-based program, Menactra, which provides protection against four strains of IMD (A, C, W-135 and Y), replaces the current vaccine which guards against only the C strain. One-year old children, who are also immunized against IMD, will continue to receive the previous vaccine. Menactra is approved for use in Canada in children two years of age and older.     

IMD is most common in young children and youth and can make them extremely ill very quickly. The disease can lead to serious infections of the blood, the lining of the brain and the spinal cord. Among those who survive the illness, it can cause permanent disability including deafness, neurological damage, and loss of limbs.

Quick Facts

  • IMD is a rare but serious disease caused by a specific strain of bacteria, neisseria meningitidis. Up to 10 per cent of the population carry the bacteria; however, most people never develop an active form of the disease.
  • From 1997 to 2007, an average of 67 cases of IMD was reported in Ontario each year.
  • IMD is fatal in 8-15 per cent of cases.
  • Menactra has been available in Ontario since 2007 to people with high risk medical conditions and for close contacts of a case of IMD.
