Read all of this leaflet carefully before your child receives/ you receive this
vaccine as it contains important information for you.

Keep this leaflet. You may need to read it again.
If you have any further questions, please ask your doctor or your pharmacist.
This vaccine has been prescribed for your child/you only. Do not pass it on to
others. It may harm them.

1. What Hiberix is and what it is used for
Hiberix is a vaccine containing a non-infectious extract (polysaccharide) of
Haemophilus influenzae type b (Hib). In order for the polysaccharide to be effective, it
is chemically linked to inactivated tetanus toxoid. The body responds to the vaccine
by making antibodies which will provide long-term protection against the diseases
caused by the bacteria.
Haemophilus influenzae type b most frequently causes meningitis, in which the
coverings of the surface of the brain become infected and inflamed. There can be
serious complications such as mental retardation, cerebral palsy, deafness, epilepsy
or partial blindness. Hib infection also causes inflammation of the throat and
occasionally death by suffocation. Less commonly, the bacteria can also infect the
blood, heart, lungs, bones, joints and tissues of the eyes and mouth.
Vaccination is the best way to protect against these diseases. This vaccine will only
protect your child against diseases caused by Haemophilus influenzae type b. Since
the national introduction of Haemophilus influenzae type b vaccine for young children
in 1992, the number of cases of illness in the UK has fallen dramatically. It is very
important for all young children to be vaccinated to maintain this reduction in the
number of cases, and so to save lives and prevent disability.
2. What you need to know before your child receives/you receive Hiberix
Do not take Hiberix:
• if your child has/you have previously had an allergic reaction to Hiberix, to any Hib
vaccine, to tetanus toxoid or to any other ingredients present in the vaccine (listed
in section 6)
• if your child/you have a fever or an infection

• if your child/you have ever been vaccinated against Haemophilus influenzae type b
and felt unwell following the vaccination
Warnings and precautions:
Talk to your doctor, pharmacist or nurse before receiving Hiberix
 if your child/you have any bleeding or blood disorders
 if your child/you have any illness that may affect the immune system
 if your child/you taking medicines or having any treatment which may affect the
immune system
 if your child was born very prematurely (born ≤28 weeks of gestation), he/she may
have short episodes of breathing difficulties (longer gaps between breaths than
normal) for 2 or 3 days after vaccination. Your doctor will decide if your child
requires monitoring during this time.
Fainting can occur (mostly in adolescents) following, or even before any needle
injection. Therefore tell the doctor or nurse if you or your child fainted with a previous
Other medicines and Hiberix

taking, have recently taken or might take any other medicines, including medicines
obtained without a prescription or has recently received any other vaccine.

Hiberix contains sodium
This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e.
essentially “sodium free”.
3. How Hiberix is given
0.5 ml of Hiberix is injected into a muscle.
If your child is less than 13 months old, the first vaccination should be given not
earlier than two months of age. Two further injections should then be given at least
one month apart.
If your child is aged over 13 months, only a single injection of Hiberix is needed for
If your child receives/you receive more Hiberix than he/she/you should
It is very unlikely that your child/you will receive too much or too little vaccine
because each dose is provided in a separate vial and the vaccine is given by a
doctor or nurse. If you are concerned about the dose or doses that have been given,
please talk to your doctor or nurse.
If you forget to take your child for vaccination with Hiberix

Your doctor or nurse will advise when your child should attend for these injections. If
you miss an appointment, it is very important that you contact the surgery or clinic
and make a new appointment for your child to have the missed dose or doses as
soon as possible.
