Common questions about Hib
Hib – short for haemophilus influenza type b (Hib) – is a bacterial infection that can cause meningitis (a life-threatening infection of the lining around your child’s spinal cord and the brain), pneumonia, swelling of the throat, deafness, and even death.
Before immunization, Hib was the most common cause of childhood bacterial meningitis, which is a very serious disease.
Although Hib is short for haemophilus influenza type b, it should not be confused with influenza. Hib is completely different than influenza or “the flu.”
Hib is spread through an infected person coughing and sneezing. Children who touch toys, food items, dishes, or other objects that have been sneezed or coughed on by someone with Hib can also be infected.
The different illnesses that Hib causes have different symptoms.
Symptoms of meningitis include:
- stiff neck
- sudden fever drowsiness
- irritability or fussiness
- intense headache
- a skin rash that spreads rapidly and begins as reddish/purplish spots that don't disappear when pressed
Symptoms of pneumonia include:
- difficulty breathing
- a cough with rust or green-coloured phlegm (mucus)
- teeth chattering
- chest pain
- fast breathing and heartbeat
- bluish lips and fingernails from lack of oxygen in the blood
- feeling confused or strange
- feeling very tired
Hib can cause bacterial meningitis, which is a very serious disease, particularly for children. About one in 20 children with Hib-caused bacterial meningitis will die, even with treatment.
Among those who live, about one in three of these children will have permanent brain damage.
Antibiotics can be used to help treat some Hib-caused infections, but Hib-related infections can be very serious, and treatment might not help. For example, even with treatment, one in 20 children who get bacterial meningitis caused by Hib will die. Among those who live, about one in three of these children will have permanent brain damage.
To be protected against Hib, your child needs multiple doses of the DTaP-IPV-Hib vaccine, at the ages and stages recommended in the routine schedule.
Your child is recommended to receive the DTaP-IPV-Hib at two months of age, followed by a dose at four months of age, at six months of age, and at 18 months of age.
The side effects your child may have after immunization depend on which vaccine they received. To find this information, click on the vaccine name in the Routine Immunization Schedule or from the list of Vaccine Information Sheets.
