1. Why is my child being given Act-HIB?

Act-HIB contains the active ingredient Haemophilus type b polysaccharide conjugated to tetanus protein. Act-HIB is a conjugate vaccine that helps protect your child against Haemophilus Influenzae type b infections.

This vaccine does not provide protection against infections due to other types of Haemophilus Influenzae or against cases of meningitis of other origins.

The vaccine may be administered to children from 2 months of age to 5 years of age.

Under no circumstances can the tetanus protein contained in this vaccine be used to replace the usual tetanus vaccination.

When an injection of Act-HIB is given, the immune system (body’s natural defences) will protect against Haemophilus Influenzae type b infections. However, as with any vaccine, Act-HIB may not protect 100% of vaccinated individuals.

2. What should I know before my child is given Act-HIB?


Do not use Act-HIB if your child:

  • is allergic to the active substance, formaldehyde or any of the ingredients listed at the end of this leaflet.
    symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue or other parts of the body, skin rash, itching or hives
  • has had a life-threatening reaction after previous administration of this vaccine or a vaccine containing the same substances.
  • has an illness with febrile or acute infection. The vaccination should be postponed until after your child has recovered.

Check with your doctor if your child:

  • has a poor immune response (immunosuppression) due to disease or medicines, because their response to the vaccine may be limited.
  • has a bleeding disorder
  • has an allergy to latex
  • has fainted with previous injections. Fainting can occur following, or even before, any needle injections
  • has any other medical conditions
  • take any medicines for any other condition

After vaccination, your child may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

3. What if my child is taking other medicines?

Tell your doctor or pharmacist if your child is taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Having other vaccines:

  • Tell your doctor if your child has had any vaccines in the last 4 weeks.
    Your doctor will advise you if Act-HIB is to be given with another vaccine as a separate injection.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements your child is taking and if these affect Act-HIB.

4. How Act-HIB is given

How much to use

  • Act-HIB is administered to your child by your doctor or nurse.
  • Act-Hib is given as an injection. For children under the age of 24 months, Act-HIB is injected into the upper thigh muscle. In older children who have started walking, the vaccine is usually injected into the upper arm muscle.

When to use Act-HIB


  • Before 6 months of age, administration of 3 successive 0.5mL doses at intervals of one to two months.
  • Between 6 and 12 months of age, administration of 2 successive 0.5mL doses at intervals of one to two months.
  • This is followed in both cases by a booster dose as per the National Immunisation Schedule.


  • In children over 12 months of age, a single dose of 0.5mL.

If your child misses a dose of Act-HIB

If your child misses a dose, talk to your doctor and arrange another visit as soon as possible.

If your child received too much Act-HIB

Overdose is most unlikely because your doctor or nurse gives the injections. If you have any concerns, ask your doctor.

5. What should I know after my child is given Act-HIB?

Things you should do

  • keep an updated record of your vaccinations.
  • keep follow-up appointments with your doctor or clinic.
    It is important for your child to have follow-up doses of Act-HIB at the appropriate times to make sure the vaccines are providing protection against Haemophilus Influenzae type b.
  • report any side effects to your doctor.

Call your doctor straight away if your child:

  • does not feel well after having Act-HIB

Remind any doctor, dentist or pharmacist you visit that your child had Act-HIB.

Looking after your child’s medicine

Act-HIB is usually stored in the doctor’s surgery or clinic, or at the pharmacy. However, if you need to store Act-HIB:

Follow the instructions in the carton on how to take care of your medicine properly.

Keep Act-HIB in the original pack until it is time for it to be given.

Store in a refrigerator (2°C – 8°C). Do not freeze. Freezing destroys the vaccine.

Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

Getting rid of any unwanted medicine

Medicines should not be disposed of via wastewater or household waste. Ask your pharmacist how to dispose of medicines no longer required. These measures will help to protect the environment.

If your child no longer needs this vaccine or it is out of date, take it to any pharmacy for safe disposal.

Do not use Act-HIB after the expiry date which is stated on the carton after EXP. The expiry date refers to the last day of that month.
