(diphtheria and tetanus toxoids and acellular pertussis) Vaccine Adsorbed


Certiva (diphtheria and tetanus toxoids and acellular pertussis vaccine adsorbed) TM (Diphtheria and Tetanus sterile combination of diphtheria, Toxoids and Acellular Pertussis Vaccine Adsorbed) is a tetanus, and pertussis toxoids (one pertussis antigen, inactivated pertussis toxin), adsorbed onto aluminum hydroxide.1 It is intended for intramuscular injection only. After shaking, Certiva (diphtheria and tetanus toxoids and acellular pertussis vaccine adsorbed) TM is a homogeneous white suspension. The pertussis toxin (PT) is isolated from Phase 1 Boraktella pertussis grown in modified Stainer-Scholte medium. After purification by afIinity chromatography, which includes the use of fetuin, a bovine serum protein, as an aflinity ligand, PT is detoxified using hydrogen peroxide.

Diphtheria toxin is derived from Corynebacterium diphtheriae grown in Stainers Diphtheria Culture Medium, containing casein hydrolysate, and is purified by fractional precipitation with ammonium sulfate. Tetanus toxin is derived from Clostridium tetani grown in modified Mueller and Miller Medium, containing casein hydrolysate, and is purified by precipitation with ammonium sulfate.2 The purified diphtheria and tetanus toxins are detoxified using formaldehyde.

Each antigen is individually adsorbed onto aluminum hydroxide. 2 Each 0.5 ml dose of vaccine is formulated to contain 15 Lf diphtheria toxoid, 6 Lf tetanus toxoid, 40 mcg pertussis toxoid, 0.5 mg aluminum as aluminum hydroxide, and is preserved with 0.01% thimerosal (mercury derivative). The product may contain residual fetuin. The residual free formaldehyde content by assay is less than or equal to 10 ppm. The diphtheria and tetanus toxoids each induce not less than 2 units of antitoxin per ml in the guinea pig potency test. The potency of the pertussis toxoid is evaluated by measurement of antibody titers to pertussis toxin in immunized mice using an ELISA.

Diphtheria and tetanus toxoid bulks for further manufacturing use are produced by Statens Seruminstitut, Copenhagen, Denmark. The pertussis toxoid is manufactured by North American Vaccine, Inc., Beltsville, Maryland. Final formulation and release of Certiva (diphtheria and tetanus toxoids and acellular pertussis vaccine adsorbed) TM are conducted by North American Vaccine, Inc.
