Hib Vaccine

What is Hib vaccine?

Hib vaccine prevents serious infections caused by a type of bacteria called Haemophilus influenzae type b. Such infections include meningitis (an infection of the covering of the brain and spinal cord), pneumonia (lung infection), and epiglottitis (a severe throat infection).

Hib is injected intramuscularly in the mid thigh region of the baby.
