Haemophilus influenzae disease


How is invasive Haemophilus influenzae type b prevented?

The most important way to prevent Haemophilus influenzae type b (Hib) is to make sure you and your children are vaccinated.

The Hib vaccine is given by needle. Like all vaccines authorized for use in Canada, it went through several stages of testing before being authorized for use.

The Hib vaccine is usually given as part of a combined vaccine which provides protection against other diseases. The Canadian Immunization Guide recommends that all children get 4 doses of the combined vaccine. These doses are usually given at 2, 4, 6 and 18 months of age.

Hib vaccines are safe, effective and free.

Side effects of this vaccine are usually very mild. Your child’s arm or thigh might be a bit red or sore where the needle went in. Your child may also:

  • have a slight fever,
  • be fussy,
  • be sleepier than usual, and/or
  • have less appetite than usual.

These side effects usually happen 12 to 24 hours after the immunization and go away within a few days.
