What is haemophilus influenzae type b vaccine?
Haemophilus influenzae is a serious disease caused by bacteria. It usually strikes children younger than 5 years old. Haemophilus influenzae is spread from person to person. Children and adults may have the bacteria and not know it. If the germs stay in a child's nose and throat, the child probably will not get sick. But sometimes the germs spread into the lungs or the bloodstream, and then Hib can cause serious problems. Hib vaccine exposes the individual to a small amount of the bacteria (or to a protein from the bacteria) and causes the body to develop immunity to the disease.
Before Hib vaccine, Hib was the leading cause of bacterial meningitis among children under 5 years old in the United States. Meningitis is an infection of the brain and spinal cord coverings, which can lead to lasting brain damage and deafness. Hib disease can also cause pneumonia; severe swelling in the throat, making it hard to breathe; infections of the blood, joints, bone, and covering of the heart; and death.
Haemophilus influenzae vaccine (Hib) can help prevent the disease. Many more children would get the disease if vaccination did not occur.

a serious allergic reaction including swelling of the lips, tongue, or face; difficulty breathing; closing of the throat; hives; paleness; weakness; dizziness; or a fast heart beat within a few minutes to a few hours after the shot;
high fever; or
Other less serious side effects may be more likely to occur. Talk to your doctor if you experience:
fever over 101 degrees Fahrenheit (about up to 1 child in 20); or
redness, warmth, or swelling where the shot was given (up to about 1 child in 4).
If these problems happen, they usually start within a day of vaccination. They may last 2-3 days.
