1. What Act-HIB is and what it is used for

Act-HIB Haemophilus influenzae type b, the conjugate vaccine is a bacterial vaccine used to prevent infection caused by Haemophilus influenzae type b (such as meningitis, blood poisoning, cellulite, joint inflammation, laryngitis, pneumonia, bone rot from 2 months of age).

The vaccine activates the body’s immune system to provide protection ( antibodies ) against Haemophilus influenzae type b.

2. What you need to know before using Act-HIB

Do not use Act-HIB

If the child to be vaccinated:

  • is allergic (hypersensitive) to any of the ingredients of Act-HIB, especially the tetanus protein and formaldehyde.
  • previously had a severe reaction after vaccination with Act-HIB or any other vaccine containing the same substances.
  • have a high fever or an acute infection, the vaccination should be postponed.

Warnings and precautions

Talk to a doctor before the child is vaccinated.

  • if your child has a latex allergy. The syringe tip cap on the prefilled syringes contains latex. May cause severe allergic reactions.

Act-HIB does not protect against infection caused by other types of Haemophilus influenzae or against meningitis of other origins.

The tetanus protein contained in the Act-HIB can under no circumstances be used to replace the standard vaccination against tetanus ( tetanus ).

Before Act-HIB is given, the recipient’s parent or guardian or the adult recipient must be asked about personal history, family history, and recent health status, including vaccination history, current health status, and any side effects from previous vaccinations. The vaccination procedure must be well considered for patients who have had a severe reaction within 48 hours after a previous injection containing similar ingredients.

A treatment that lowers the immune system or a condition with a reduced immune response can cause a weakened immune response to the vaccine. The recommendation is therefore to wait with the vaccination until after the end of treatment or to ensure that the patient is well protected. Vaccination of patients with chronic immune suppression in HIV – infection, asplenia, or sickle cell disease is still recommended even if the antibody response may be limited.

As with all injectable vaccines, the vaccine must be given with caution to patients with thrombocytopenia or bleeding disorders as bleeding may occur after intramuscular injection in these patients.

Effect on blood tests

Because antigen in the urine has been detected in some cases within 2 weeks of the patient receiving Act-HIB, false-positive reactions are possible in suspected positive Haemophilus influenzae type b disease. Therefore, in such cases, the detection of antigen in the urine may not have a decisive diagnostic value in suspected Haemophilus influenzae type b disease.


The possible risk of respiratory arrest ( apnea ) and the need for respiratory monitoring during the first 48-72 hours after administration of the basic vaccination schedule to very premature infants (born at gestational week ≤28) should be considered and especially for children who have had a respiratory immaturity.

As the benefit of vaccination is great within this group of children, one should not refrain from or postpone vaccination.

Other medicines and Act-HIB

Tell your doctor or pharmacist if the child to be vaccinated is taking, has recently taken, or might take other medicines.

Tell your doctor if your child is taking so-called immunosuppressive drugs as the effect of the vaccination may be worse.

Act-HIB can be injected at the same time as other recommended vaccines against diphtheria, tetanus (tetanus), pertussis (pertussis), and polio, at the same injection site if combined or at two different injection sites if given simultaneously but as two different injections.

Act-HIB can be given concomitantly with the hepatitis B or MPR (measles-mumps-rubella) vaccine at two different injection sites.

Pregnancy and breastfeeding


Vaccination of adults against Haemophilus influenzae type b is uncommon. Data on the use of this vaccine in pregnant women are limited. Therefore, administration of the vaccine during pregnancy is not recommended. Act-HIB should be given to pregnant women only if there is a clear need and after an assessment of the risks and benefits.


Vaccination of adults against Haemophilus influenzae type b is uncommon. It is not known if this vaccine is excreted in human milk. Therefore, caution should be exercised when administering Act-HIB to a nursing mother.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

The following information is intended for healthcare professionals only:

In accordance with the immunization programs for children, the recommendations of the WHO (World Health Organization) and ACIP (Advisory Committee on Immunization Practices) administered Act-HIB is rarely alone but is often given at the same time as, or combined with other vaccines, such as vaccines against diphtheria-tetanus (lockjaw ) -pertussis). The side effects of Act-HIB reflect this concomitant use

To think about before and during vaccination

  • Vaccination should be postponed in case of fever or acute febrile illness.
  • Do not give as an intravascular injection: make sure that the needle does not penetrate any blood vessels.
  • As with all injectable vaccines, the vaccine must be administered with caution to patients with thrombocytopenia or hemorrhagic disease, as bleeding may occur during intramuscular administration to these patients.
  • Before any biological product is injected, the person in charge of administration must take all known precautions to prevent an allergic reaction or a reaction of any other type. As with all injectable vaccines, appropriate medical treatment and monitoring should always be readily available in the event of a rare anaphylactic reaction following vaccination.
  • Any unused product or waste material should be disposed of in accordance with local requirements.


Reconstitute the vaccine by injecting the contents of the supplied disposable syringe with diluent (0.5 ml) into the powder vial and shaking vigorously until the powder is completely dissolved. The vaccine is then drawn into the disposable syringe and injected. Shake again just before injecting one.

Use the product immediately after reconstitution.

After reconstitution, the vaccine is clear and colorless.

Act-HIB can be given in the same syringe as the inactivated polio vaccine. Act-HIB can be given at the same time as other vaccines. In such cases, separate syringes and injection sites must be used.


The reconstituted vaccine should preferably be administered intramuscularly, although it may also be given subcutaneously.

The recommended site of administration in infants is the anterolateral part of the thigh and in children the deltoid region.
