Hib vaccine. Haemophilus influenzae type B vaccine is a vaccine used to prevent Haemophilus influenzae type b (Hib) infection. In countries that include it as a routine vaccine, rates of severe Hib infections have decreased more than 90%. It has therefore resulted in a decrease in the rate of meningitis, pneumonia, and epiglottitis.
The Advisory Committee on Immunization Practices (ACIP) has approved the Hib vaccine for use with children at 2, 4, 6 and 12-15 months of age. The new vaccine, MenHibrix, has been approved for children ages 6 weeks through 18 months.
