What is Haemophilus Type B disease?
Haemophilus type b disease is caused by bacteria called Haemophilus influenzae type b, or Hib for short. Sometimes it’s called “H. flu.”
There are six different types of this bacteria: a through f. Type b organisms account for 95% of all strains that cause serious Hib disease, and this is the type against which the Hib vaccine protects.
