HAEMOPHILUS b CONJUGATE VACCINE
- haemophilus b conjugate vaccine is indicated for the immunization of children 2 months to 59 months of age against invasive disease caused by Haemophilus influenzae type b. (for infants born either prematurely or at term vaccination should be started at the chronologic age of 2 months)
- Act-HIB(R) is NOT a live vaccine
- Haemophilus influenzae type b (Hib) is the most common cause of invasive bacterial disease in young children
- approximately 55 to 65% of all invasive Hib infections present as meningitis; Hib can also result in epiglottitis, septicemia, cellulitis, pneumonia and other invasive conditions
- other strains of H. influenzae (non type b) are commonly found in otitis media, sinusitis, bronchitis and other upper respiratory tract infections; these conditions are seldom associated with type b organisms
- Act-HIB(R) (the brand that we will be using at SJHC) is a conjugate vaccine: it contains a purified capsular polysaccharide of H.influenzae (type b) bound to tetanus protein; a conjugate vaccine results in stimulation of the immune system
- local reactions including pain, redness, swelling and induration may occur at injection site
- systemic reactions including fever, irritability, drowsiness, prolonged or abnormal crying, vomiting have occurred
- high fever, serious local reactions and systemic reactions temporally associated with injection must be reported to the medical officer of health (Middlesex-London Public Health Unit (519)663-5317)
- Act-HIB(R) is the infant Hib conjugate vaccine which is supplied free of charge in Ontario; indicate the TRADE NAME both in the infant's chart AND personal
- Connaught's DPT Polio Adsorbed vaccine may be used for the reconstitution of the lyophilized (freeze-dried powder) Act-HIB(R). This provides an efficient means of administering routine immunization against diphtheria, pertussis, tetanus, poliomyelitis and H.influenzae type b in a single injection
- note that Hib vaccine will not prevent meningitis due to non-Hib infectious agents, such as meningococci or streptococci
- 0.5 mL IM, after reconstitution with Connaught's DPT Polio adsorbed vaccine
- Act-HIB(R) is supplied as a lyophilized powder. It may be reconstituted with Connaught's DPT Polio Adsorbed vaccine (which is sold under the trade name QUADRACEL(R)) as follows:
- Shake the ampoule (DPT Polio Adsorbed vaccine - QUADRACEL(R)) well to uniformly distribute the suspension before withdrawing the contents.
- Inject all of the DPT Polio Adsorbed vaccine - QUADRACEL(R) into the vial of Act-HIB(R) (ie. the lyophilized powder)
- Swirl the vial until a cloudy, uniform suspension results. Avoid foaming.
