Haemophilus influenzae type B (Hib)
The Hib is an inactivated vaccine, which is made chemically by conjugating a polysaccharide (sugar) to a protein. This long chain of sugar molecules makes up the surface capsule of the bacterium. The Hib vaccine is given as an injection into the anterolateral thigh muscle (in infants and toddlers) or in the deltoid muscle of older children.
Recommended age of administration:
• Hib should be received by the Infants as part of their routine immunization below the age of five years.
• This given as three at 6,10 and 14 weeks after birth followed by a booster dose at 1.5 years.
• Older children and adults who are at increased risk for invasive Hib disease should be vaccinated.
Individuals with following conditions should not receive:
• Individuals with life-threatening allergic reaction to a previous dose of Hib vaccine should not get another dose.
• Infants lesser than six weeks of age should not get Hib vaccine because a dose given at this time may reduce the infant’s response to subsequent doses.
• Persons with a moderate or severe acute illness should postpone receiving the vaccine until their condition has improved.
