What is the History of Hib in America and Other Countries?

History of Hib

Before the Hib vaccine was introduced in the U.S., Hib-caused meningitis occurred in children ages 6 months to 2 years at the rate of 12,000 to 20,000 cases per year, and caused 500 deaths annually.1

From 1996 through 2000 after the introduction of the vaccine, an average of 1,247 invasive H. Influenzae infections per year were reported to the CDC. Of this number, about 272 were children under age 5. An average 68 cases per year were attributable to Hib.2
