Haemophilus Influenza type B (HIB) can be contracted through the air or by direct contact. HIB vaccination is commonly given in the 2nd, 4th, 6th and 12th month of age and is recommended for all children under 5 years of age. This vaccine can sometimes be included when other shots are given.
Some individuals who should NOT receive the vaccine include:
- anyone who has had a severe allergic reaction to the vaccination previously or any of its ingredients, or
- children under 6 weeks of age.
Please speak with a physician before receiving the injection if the individual is moderately or severely ill at the time of the injection.
Haemophilus influenza type B (Hib) is a leading cause of invasive bacterial infection among children in the United States. Hib causes pneumonia, bloodstream infection, epiglottitis (an infection that can block the windpipe and lead to serious, life threatening breathing problems), and infections of the ears, joints, skin, or heart. HIB also can cause meningitis, an infection of the covering of the brain and spinal cord. It has caused complications such as permanent brain damage, epiglottis, sepsis, arthritis, pneumonia and even death.
Transmission occurs through direct contact with respiratory droplets from an infected person. Unimmunized children <4 years old, household or daycare contacts of a person with Hib disease, American Indian/Alaskan Natives, and persons with sickle cell disease, asplenia, HIV, certain immunodeficiency syndromes, and cancers are at increased risk for invasive Hib. Routine vaccination of children has reduced the incidence of invasive Hib infection by 99%.
