(Meningococcal Groups C and Y and Haemophilus b Tetanus Toxoid Conjugate Vaccine)
MENHIBRIX (Meningococcal Groups C and Y and Haemophilus b Tetanus Toxoid Conjugate Vaccine), for intramuscular injection, is supplied as a sterile, lyophilized powder which is reconstituted at the time of use with the accompanying saline diluent. MENHIBRIX contains Neisseria meningitidis serogroup C and Y capsular polysaccharide antigens and Haemophilus b capsular polysaccharide (polyribosyl-ribitol-phosphate [PRP]). The Neisseria meningitidis C strain and Y strain are grown in semi-synthetic media and undergo heat inactivation and purification. The PRP is a high molecular weight polymer prepared from the Haemophilus influenzae type b strain 20,752 grown in a synthetic medium that undergoes heat inactivation and purification. The tetanus toxin, prepared from Clostridium tetani grown in a semi-synthetic medium, is detoxified with formaldehyde and purified. Each capsular polysaccharide is individually covalently bound to the inactivated tetanus toxoid. After purification, the conjugate is lyophilized in the presence of sucrose as a stabilizer. The diluent for MENHIBRIX is a sterile saline solution (0.9% sodium chloride) supplied in vials.
When MENHIBRIX is reconstituted with the accompanying saline diluent, each 0.5-mL dose is formulated to contain 5 mcg of purified Neisseria meningitidis C capsular polysaccharide conjugated to approximately 5 mcg of tetanus toxoid, 5 mcg of purified Neisseria meningitidis Y capsular polysaccharide conjugated to approximately 6.5 mcg of tetanus toxoid, and 2.5 mcg of purified Haemophilus b capsular polysaccharide conjugated to approximately 6.25 mcg of tetanus toxoid. Each dose also contains 96.8 mcg of Tris (trometamol)-HCl, 12.6 mg of sucrose, and ≤ 0.72 mcg of residual formaldehyde. MENHIBRIX does not contain preservatives. The vial stoppers do not contain latex.
