2-year Follow-up After a Single Dose Acellular Pertussis Vaccination

"Pertagen (aP BioNet) was produced with a recombinant B pertussis strain that was genetically inactivated by the introduction of mutations (Arg9Lys and Glu129Gly) in the ptx operon of the S1 gene. Each 0.5 mL dose of Pertagen (aP BioNet) contained 5 µg PTgen, 5 µg FHA, and 0.3 mg as aluminium cation.~The study vaccine was presented in a single-dose prefilled syringe. Each subject was received one intramuscular injection in the non-dominant deltoid region in parent protocol TDA202."

"Boostagen (TdaP BioNet) was produced with a recombinant B pertussis strain that was genetically inactivated by the introduction of mutations (Arg9Lys and Glu129Gly) in the ptx operon of the S1 gene. Each 0.5 mL dose of Boostagen (TdaP BioNet) contained 5 µg PTgen, 5 µg FHA, and 0.3 mg as aluminium cation. TDaP dose additional contained at least 7.5 Lf tetanus toxoid and at least 2.0 Lf diphtheria toxoid.~The study vaccine was presented in a single-dose prefilled syringe. Each subject was received one intramuscular injection in the non-dominant deltoid region in parent protocol TDA202."

"Comparator vaccine, Adacel (Sanofi-Pasteur, North York, ON, Canada) was produced chemically inactivated pertussis toxin. Each 0.5 mL dose of Adacel (as comparator vaccine) contained 2.5 µg PTchem, 5 µg FHA, 3 µg pertactin, 5 µg fimbriae types 2 and 3, 5.0 Lf tetanus toxoid, 2.0 Lf diphtheria toxoid and 0.33 mg as aluminium cation.~The study vaccine was presented in a single-dose prefilled syringe. Each subject was received one intramuscular injection in the non-dominant deltoid region in parent protocol TDA202"
