About Haemophilus Influenzae Type B (Hib)

Haemophilus influenzae disease is a name for any illness caused by bacteria called H. influenzae. Some of these illnesses, like ear infections, are mild while others, like bloodstream infections, are very serious. In spite of the name, H. influenzae do not cause influenza (the flu). Vaccines can prevent one type of H. influenzae (type b or Hib) disease.

Vaccines are available that can help prevent Haemophilus influenzae type b or Hib disease. These vaccines do not provide protection against other types of Haemophilus influenzae disease. Haemophilus influenzae disease is any type of infection caused by Haemophilus influenzae bacteria.

CDC recommends Hib vaccination for all children younger than 5 years old in the United States. CDC does not recommend Hib vaccination for most people 5 years or older unless they:

  • Have certain medical conditions and are unvaccinated
  • Receive a bone marrow transplant

Talk with your or your child’s healthcare professional if you have questions about Hib vaccines.
