Last reviewed July 2026
Who is this for?
The Haemophilus Influenzae Type B (Hib) vaccine is an injection that helps the body build protection against a dangerous bacteria called Haemophilus influenzae type b, which can cause serious infections like meningitis (brain infection) and pneumonia in young children.
Activates humoral and cell-mediated immunity by presenting the conjugated polyribosylribitol phosphate (PRP) capsular polysaccharide antigen to B and T lymphocytes, stimulating the production of opsonizing antibodies and memory cells that prevent bacterial colonization and invasive disease caused by Haemophilus influenzae type b.
Prevention of meningitis (brain infection), pneumonia, blood infection (sepsis), joint infection, and throat swelling (epiglottitis) caused by the Hib bacteria, mostly in babies and young children

If your child misses a scheduled dose, take them to the clinic as soon as you can. The health worker will continue the schedule from where it stopped, so there is no need to restart from the beginning.
Always get your child vaccinated at a recognized government health centre or trusted private hospital, and do not buy vaccines from unauthorized sellers. Make sure you complete all the scheduled doses for full protection. Keep your child's immunization card safe so health workers can track their progress.
Medicines that weaken the immune system (like steroids or cancer drugs) may reduce how well the vaccine works. Let your doctor know if the child is on any medication. The Hib vaccine is commonly given alongside other childhood vaccines safely.
