  • There are two forms of meningococcal disease: meningitis (infection of the lining of the brain and spinal cord) and bacteremia (a blood infection)

  • Spread by kissing, coughing and sneezing. Also spread by sharing drinks, toothbrushes, mouth guards and other objects that go in the mouth.
  • People can spread the bacteria without knowing they have it
  • Meningococcal disease kills one out of 10 people who get it, even with early treatment
  • One out of three survivors will have some form of permanent disability (e.g. limb amputation(s), deafness, and seizures)

  • Two to four doses are required, depending on the age at first dose

Yes!  You may have no reaction or mild symptoms that include:

  • Redness, swelling, and pain where the needle went in
  • Fever – higher temperatures may occur in children up to three years of age, speak with a doctor/nurse about the timing of your appointment and taking acetaminophen.
  • Children may become fussy or sleepier than usual;
  • These normal reactions usually last between 12 and 24 hours.

When should I call my doctor?

Serious reactions after vaccination are very rare.  Get immediate medical help if you/your child have any unusual symptoms such as:

  • trouble breathing, swelling in your face/mouth and/or blotchy skin (hives)
  • fever above 40°C (104°F);
  • crying or fussing for more than 24 hours;
  • worsening swelling, redness, and/or pain where the needle went in;
  • unusual sleepiness (difficult to wake)

You know best.  If you notice anything that is not normal after a vaccination, check with your healthcare provider.

Talk to your healthcare provider if you have any questions.
