Doctors’ Notes


Haemophilus Influenzae Type B (Hib) Vaccine

The Hib Vaccine protects against Haemophilus influenzae type b (Hib).

Haemophilus influenzae type b (Hib) is a bacterial infection the generally affects children under 5 years of age. It’s transmitted via direct contact and can stay in the child’s nose or throat not causing illness, or spread to the lungs or bloodstream and cause serious problems. Prior to the vaccine, Hib was the leading cause of bacterial meningitis, an infection of the lining of the brain and spinal cord. Hib can also cause pneumonia, severe swelling in the throat causing difficulty breathing, infections of the blood, joints, bones and covering of the heart and death, and even milder illnesses such as ear infections and bronchitis.

Every year before the vaccine, about 20,000 children got invasive Hib disease, and about 1,000 died. Over half the children who developed invasive disease were under 1 year old. Today, fewer than 50 cases of Hib occur each year in young children in the U.S. Studies have shown the vaccine to be  more than 95% effective in protecting children from H. flu.
