Before the Hib vaccine was available, Hib disease was the leading cause of bacterial meningitis among children under 5 years old in the U.S. Hib disease can also cause pneumonia; severe swelling in the throat; infections of the blood, joints, bones, and covering of the heart; and death. Since the vaccine was introduced, bacterial meningitis has been reduced by about 98 percent.


The Hib vaccine was approved for use in the U.S. in 1990.
