Anti-PT and anti-FHA Ab concentrations are determined in terms of endotoxin units per millilitre (EU/mL).
Anti-PT and anti-FHA Ab levels are measured by electrochemiluminescence immunoassay (ECL) and anti-PT and anti-FHA Ab concentrations are determined in terms of EU/mL.
Anti-diphtheria, anti-tetanus, anti-PT and anti-FHA Ab levels are measured by ECL. Anti-poliovirus types 1, 2, and 3 Ab levels are measured by neutralisation assay. Anti-Hep B Ab levels are measured by VITROS ECi/ECiQ Immunodiagnostic system using chemiluminescence detection technology. Anti-polyribosylribitol phosphate (PRP) Ab levels are measured using a Farr-type radioimmunoassay (RIA). Ab concentrations are determined as: anti-diphtheria \>=0.01 international units (IU)/mL, \>=0.1 IU/mL, 1.0 IU/mL, anti-tetanus \>=0.01 IU/mL, \>=0.1 IU/mL, and \>=1.0 IU/mL, anti-PT and anti-FHA EU/mL, anti-PRP \>=0.15 microgram (mcg)/mL, \>=1.0 mcg/mL, anti-Poliovirus types 1, 2, and 3 Ab titers \>=8 (1/dilution \[dil\]), Anti-Hep B \>=10 milli (m) IU/mL, and \>=100 mIU/mL.
Seroprotection is determined as: anti-diptheria Ab concentrations \>=0.01 IU/mL, \>=0.1 IU/mL, and \>=1.0 IU/mL, anti-tetanus Ab concentrations \>=0.01 IU/mL, \>=0.1 IU/mL, and \>=1.0 IU/mL, anti-PT and anti-FHA Ab concentrations EU/mL (\>=LLOQ and \>=4\*LLOQ), anti-PRP Ab concentrations \>=0.15 mcg/mL and \>=1.0 mcg/mL, anti-poliovirus 1, 2, and 3 Ab titers \>=8 (1/dil), anti-Hep B Ab concentrations \>=10 mIU/mL and \>=100 mIU/mL.
Vaccine response is defined for anti-PT and anti-FHA as Ab post-Dose 3 concentrations \>=4\*LLOQ, if pre-Dose (Day 0) Ab concentration is \<4\*LLOQ or 1 month after third dose (Day 90) concentrations \>= pre-Dose Ab concentrations if pre-Dose (Day 0) concentrations \>=4\*LLOQ. Seroconversion for anti-PT and anti-FHA is defined as \>=4-fold Ab concentrations increase from pre-Dose (Day 0) to 1 month after third dose (Day 90).
Anti-diphtheria, anti-tetanus, anti-PT, and anti-FHA Ab levels are measured by ECL. Anti-poliovirus types 1, 2, and 3 Ab levels are measured by neutralisation assay. Anti-Hep B Ab levels are measured by VITROS ECi/ECiQ Immunodiagnostic system using chemiluminescence detection technology. Anti-PRP Ab levels are measured using a Farr-type RIA. Ab concentrations: anti-diphtheria \>=0.01 IU/mL, \>=0.1 IU/mL, \>=1.0 IU/mL, anti-tetanus \>=0.01 IU/mL, \>=0.1 IU/mL, and \>=1.0 IU/mL, anti-PT and anti-FHA EU/mL, anti-PRP \>=0.15 mcg/mL, \>=1.0 mcg/mL, anti-poliovirus 1, 2, and 3 Ab titers \>=8 (1/dil), anti-Hep B \>=10 mIU/mL, and \>=100 mIU/mL.
Seroprotection: anti-diphtheria Ab concentrations \>=0.01 IU/mL, \>=0.1 IU/mL, and \>=1.0 IU/mL, anti-tetanus Ab concentrations \>=0.01 IU/mL, \>=0.1 IU/mL, and \>=1.0 IU/mL, anti-PT and anti-FHA Ab concentrations EU/mL (\>=LLOQ and \>=4\*LLOQ), anti-PRP Ab concentrations \>=0.15 mcg/mL and \>=1.0 mcg/mL, anti-poliovirus 1, 2, and 3 Ab titers \>=8 (1/dil), and anti-Hep B Ab concentrations \>=10 mIU/mL and \>=100 mIU/mL.
Vaccine response is defined for anti-PT and anti-FHA as \>=4 fold Ab concentrations increase from pre-dose (Day 0) to 1 month after booster dose (Day 420), if pre-Dose (Day 0) Ab concentrations \<4\*LLOQ; or \>=2 fold Ab concentrations increase from pre- dose (Day 0) to 1 month after booster dose (Day 420), if pre-dose (Day 0) Ab concentrations \>=4\*LLOQ. Seroconversion is defined for anti-PT and anti-FHA as \>=4 fold Ab concentrations increase from pre-dose (Day 0) to 1 month after booster dose.
Booster response is defined for anti-PT and anti-FHA as \>=4 fold Ab concentrations increase from pre-booster (Day 390) to 1 month after booster dose (Day 420), if pre-booster Ab concentrations \<4\*LLOQ; or \>=2 fold Ab concentrations increase from pre-booster (Day 390) to 1 month after booster dose (Day 390) if pre-Booster Ab concentrations \>=4\*LLOQ.
