Hib vaccine

Quick Reference

A vaccine that gives protection against the bacterium Haemophilus influenzae type b (Hib). Before the introduction of the vaccine in the UK in 1992, Hib was the commonest cause of meningitis in children under the age of 2 years. The vaccine, which has an excellent safety record, is currently given with the primary vaccines at two, three, and four months of age and as a booster at 12 months of age to extend protection against Hib meningitis.
