Haemophilus influenzae type b capsular olysaccharide. Inactive. Tetanus toxoid. Reconstituted vaccine: lactose, sodium chloride, water for injection. Description Hiberix is a noninfectious vaccine containing purifiedpolyribosylribitol phosphate capsular polysaccharide (PRP) ofHaemophilusinfluenzaetypebcovalently bound to tetanus toxoid. Hiberix is supplied as a white lyophilised pellet for reconstitution withsterile saline solution 0.9%. Each 0.5 mLdosecontains10microgramofpurifiedcapsularpolysaccharide of Hib covalently bound to approximately 30microgram of tetanus toxoid. The Hiberix Hib polysaccharide is extracted from a culture ofHaemophilusinfluenzae type b strain 20,752. After activation with cyanogen bromide and derivatisation with an adipic hydrazide spacer, the Hib polysaccharide iscoupled to tetanus toxoid via carbodiimide condensation. After purification,the Hib conjugate is lyophilised in the presence of a lactose stabiliser. Hiberix meets the World Health Organization requirements for the manufactureof biological substances and Hib conjugate vaccines. Actions Pharmacology. The protective efficacy of Hiberix has not beenstudied in field trials. Hiberix has however been shown to induce anti-PRPantibodies above the level known to be protective against invasive diseasedue to Haemophilus influenzae type b. An anti-PRPantibodytitregreaterthanorequalto0.15microgram/mL correlates with immediateprotectionagainstHibinfectionandgreaterthanorequalto1.0microgram/mLcorrelates with long term protection. The immunogenicity of Hiberix has been investigated in clinical studiesinvolving over 300 infants (over two months of age) using a three doseprimary vaccination schedule. Protective anti-PRP antibody titres weredemonstrated in 95 to 100% (greater than or equal to 0.15 microgram/mL) nd87 to 90% (greater than or equal to 1.0 microgram/mL) of infants one monthafter completion of the primaryschedule. Clinical trials have demonstrated the immunogenicity of Hiberix is unaltered by administration of different primary vaccination schedules. One monthafter completion of a two, four, six month or three, four, five monthprimary schedule, over 95% of infants in each group obtained anti-PRP titres greater than or equal to 0.15 microgram/mL.A boosting dose of Hiberix was given either separately (n = 19) or in combination with DTPa (n = 56) to infants aged between 15 and 18 months ho had previously received primary immunisation with Hiberix and DTPa given t separate sites. One month after administration of this booster dose, an anamnestic response was observed with anti-PRP antibody titres of greater than or equal to 0.15 microgram/mL and greater than or equal to 1.0microgram/mL being obtained in 100% and greater than 94% of infantsrespectively. Indications Active immunisation against Haemophilus influenzae type binfection in children aged from two months to five years. Contraindications Known hypersensitivity to any component of the vaccine,or to subjects having shown signs of hypersensitivity after previousadministration of Hib vaccines.As for any vaccine, Hiberix should not be administered to subjects suffering from acute severe febrile illness. However, thepresenceofminorinfectiondoesnotcontraindicate vaccination. Hiberix should never be administered intravenously. It is good clinical practice that any vaccination be preceded by a review of medical history (especially with regard to previous vaccinations and possible adverse events) and a clinical examination. As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of anaphylactic reactions following the administration of the vaccine. Native populations (native Alaskans, native American Indians) with a high incidence of Haemophilus influenzae type b disease have shown a reduced antibody response to conjugated Haemophilus influenzae type b vaccines. heimmunogenicity of Hiberix has not been studied in the Australian Aboriginal population and the possibility of a lower antibody response than that seen in clinical studies should be borne in mind. Human immunodeficiency virus (HIV) infection is not a contraindication to vaccination. However an adequate antibody response may not be obtained in patients with an immunodeficiency disorder or in patients receiving immunosuppressive therapy (see Interactions). Hiberix should be administered subcutaneously in patients with thrombocytopenia or bleeding disorders (e.g. haemophiliacs) since bleeding after intramuscular injection may occur in these patients (see Dosage and Administration).Urinary excretion of the capsular polysaccharide antigen has been reported following Hib vaccination. Therefore antigen detection within one to two weeks of vaccination may not be of diagnostic value in suspected Hib disease.An immune response to the tetanus toxoid component may occur following Hiberix vaccination, however this does not substitute for routine tetanus vaccination. Hiberix will not protect against diseases caused by other types of Haemophilus influenzae, or meningitis caused by other organisms.
Use in pregnancy. (Category B2) The effect of Hiberix on fetal development is unknown. Therefore, vaccination of pregnant women cannot be recommended. Use in lactation. The effect of Hiberix in lactation has not been assessed, as the vaccine is not intended for adult use. Adverse Reactions Clinical trial data. In controlled clinical trials, signs and symptoms were actively monitored for the first four to eight days following Hiberix vaccination and recorded on diary cards. The vaccine was generally well tolerated and most local adverse events were considered to be mild and transient. The incidence of local adverse events did not increasewith subsequent vaccine doses. As Hiberix was coadministered with either a diphtheria-tetanus-acellular pertussis vaccine or a diphtheria-tetanus-whole cell pertussis vaccine, systemic adverse events cannot be specificallyattributed to either vaccine. Most systemic events were mild and resolved spontaneously. Events are listed within body systems and categorised by frequency according to the following definitions. Very common events reported at a frequency ofgreater or equal to 1/10 patients; common events reported at a frequency of less than 1/10 but greater or equal to 1/100 patients; uncommon events reported at a frequency of less than 1/100 but greater or equal to 1/1,000 patients; rare events reported at a frequency of less than 1/1,000 patients. Local reactions. Very common: redness (> 2 cm). Common: pain, swelling (> cm). Body as a whole. Very common: fever. Common: viral infection. Uncommon: asthenia, fatigue, injury. Dermatological. Common: erythematous rash, injection site reaction. Uncommon: sweating increased, purpura. Gastrointestinal. Very common: loss of appetite, vomiting, diarrhoea. Musculoskeletal. Uncommon: spastic paralysis. Nervous system. Very common: restlessness, unusual crying. Common: nervousness, somnolence. Uncommon: insomnia, emotional lability. Respiratory. Common: rhinitis, coughing, respiratory disorder, upperrespiratory tract infection, bronchitis. Special senses. Common: conjunctivitis, otitis media.No serious adverse event was considered by investigators to be related to Hiberix alone. In two serious adverse events considered related or possibly related to vaccination, Hiberix was administered simultaneously with anacellular DTP vaccine. Postmarketing data. Postmarketing experience with Hiberix is currentlylimited. Interactions Hiberix may be administered either simultaneously, or at any time before or after different live or inactivated vaccines. However,different injectable vaccines administered concurrently should always begiven in separate sites using separate syringes. Clinical trials have shown concomitant administration of Hiberix and thediphtheria-tetanus-pertussis (acellular or whole cell) combination accines does not affect the immunogenicity of either vaccine, provided the vaccines are given at separate sites and not mixed prior to administration. As with other vaccines, it may be expected patients receiving immunosuppressive therapy (e.g. high dose steroids or cyclosporin) or patients with an immunodeficiency may not achieve an adequate immune response (see Precautions.) Hiberix must not be mixed with other vaccines in the same syringe. DosageandAdministrationHiberixissuppliedasawhitelyophilisedpelletforreconstitution with sterile 0.9% saline diluent. Hiberix is prepared by adding the entire contents of the diluent container to the vial containing the Hib vaccine pellet. The reconstituted solution must be shaken well before use, and must not be injected prior to complete dissolution of the Hib pellet. All parenteral drug and vaccine products should be inspected visually prior to administration for foreign particulate matter and/or discolouration. If either are observed, discard the diluent or reconstituted vaccine. After reconstitution Hiberix should be used promptly or kept in a refrigerator. If it is not used within 24 hours, it should be discarded because of theriskofcontamination. The recommended dose is 0.5 mL. Hiberix vaccine must be administered by intramuscular injection. In nfants and children under 12 months of age it is preferable to inject the vaccine in the anterolateral thigh because of the small size of their deltoid muscle. In children over 12 months of age the injection can alternatively be given in the deltoid region. The vaccine should be administered subcutaneously in patients with thrombocytopenia or bleeding tendencies, e.g. haemophiliacs (see Precautions). Note. Hiberix must not be given intravenously. The recommended primary vaccination course consists of three doses at two,four and six months of age. A booster dose is recommended at 18 months of age to ensure long term protection. This is consistent with the National Health and Medical Research Council recommendations for Haemophilus influenzae type b vaccination.
