Reconstitution
Lyophilised powder for solution for inj: Reconstitute the vial with the provided diluent as instructed on the label. Shake the vial well until the powder is completely dissolved. Recommendations for reconstitution may vary between individual products (refer to specific product guidelines).

Hypersensitivity.
Special Precautions
Patient with thrombocytopenia or bleeding disorder; history of Guillain-Barre syndrome (particularly for HIB vaccine conjugated to tetanus toxoid [Hiberix or ActHIB]). Patients receiving anticoagulant treatment. Immunocompromised patients (e.g. patients receiving chemotherapy, radiation therapy, or other immunosuppressive treatment [including high-dose corticosteroids]). Delay vaccination in patients with moderate or severe acute illness (with or without fever) and during periods of severe immunosuppression if appropriate. HIB conjugate vaccine does not protect against diseases caused by other types of Haemophilus influenzae nor against meningitis caused by other organisms. Immunisation using HIB vaccine conjugated to tetanus toxoid (Hiberix or ActHIB) does not substitute for routine tetanus vaccination. Infants (especially those born prematurely) and children.

General disorders and administration site conditions: Fever; inj site reactions (e.g. erythema, pain, swelling, tenderness, induration).
Metabolism and nutrition disorders: Anorexia.

Psychiatric disorders: Irritability, restlessness, uncontrollable crying.

Monitoring Parameters

Drug Interactions
May result in reduced immune response when used concomitantly with immunosuppressive treatments (e.g. antimetabolites, alkylating agents, cytotoxic agents, high-dose corticosteroids).
Lab Interference
May interfere with the result of urine antigen detection tests; antigenuria may occur for up to 2 weeks after immunisation.
Action
Description:
Mechanism of Action: Haemophilus influenzae type B (HIB) conjugate vaccine is an inactivated vaccine prepared from the purified capsular polysaccharide of Haemophilus influenzae type B conjugated via covalent linking to varying carrier proteins to improve immunogenicity. Hiberix and ActHIB contain Haemophilus influenzae type B capsular polysaccharide covalently bound to tetanus toxoid. Liquid PedvaxHIB contains Haemophilus influenzae type B capsular polysaccharide covalently bound to the outer membrane protein complex (OMPC) of Neisseria meningitidis. HIB conjugate vaccine promotes active immunity to Haemophilus influenzae type B infection by inducing the production of anticapsular antibodies.
Onset: Immunity: Approx 2 weeks (following completion of initial series).
Storage
Store between 2-8°C. Do not freeze.
