Haemophilus influenzae, type b (Hib) Vaccine

The Hib vaccine protects young children from the Haemophilus influenzae type b bacteria, which can cause severe swelling in the throat that makes it hard to breathe, a serious form of pneumonia, and a disease called bacterial meningitis. Meningitis is an infection of the membrane covering the brain and spinal cord that can lead to lasting brain damage and deafness in young children and can sometimes be fatal.

Before there was a vaccine for Hib disease, two-thirds of the children stricken with this disease were infants under one year of age.

Children should get 3 to 4 doses (depending upon product used) of the Hib Vaccine, at:

• 2 months
• 4 months
• 6 months (depending upon product used), and
• 12-15 months
