Haemophilus influenzae type b (Hib)

Contagious bacteria spread by droplets; causes meningitis, epiglottitis (respiratory obstruction), septicaemia, osteomyelitis (infection of the bones).

Effects of the disease

About one in 20 meningitis patients dies and one in four survivors has permanent brain or nerve damage. About one in 100 epiglottitis patients die.

How to immunise and when

Several doses of Hib vaccine are required to protect a child against Hib disease. Doses are given at 2,, 4, 6 and 12 months of age (but can be given from 6 weeks of age). The early doses are given in a combination vaccine with DTPa, polio and hep B.

Side effects of immunisation

About one in 20 has discomfort or local inflammation. About one in 50 has a fever.

If you have any concerns about side effects of vaccines, talk to your doctor or nurse.
