Outcomes

Primary Outcomes

Number of Seroprotected Subjects for Anti-diphtheria (Anti-D) and Anti-tetanus (Anti-T) Antibodies.

A seroprotected subject was defined as a vaccinated subject who had anti-D and anti-T antibody concentrations ≥ 0.1 international units per milliliter (IU/mL).

Time frame: At Month 0

Number of Seroprotected Subjects for Anti-diphtheria (Anti-D) and Anti-tetanus (Anti-T) Antibodies.

A seroprotected subject was defined as a vaccinated subject who had anti-D and anti-T antibody concentrations ≥ 0.1 international units per milliliter (IU/mL).

Time frame: At Month 3

Concentrations for Anti-pertussis Toxoid (Anti-PT) and Anti-pertactin (Anti-PRN) Antibodies.

Concentrations were expressed as geometric mean concentrations (GMCs). The seroprotection cut-off of the assay was ≥ 5 enzyme-linked immunosorbent assay (ELISA) units per milliliters (EL.U/mL).

Time frame: At Month 0

Concentrations for Anti-pertussis Toxoid (Anti-PT) and Anti-pertactin (Anti-PRN) Antibodies.

Concentrations were expressed as geometric mean concentrations (GMCs). The seroprotection cut-off of the assay was ≥ 5 enzyme-linked immunosorbent assay (ELISA) units per milliliters (EL.U/mL).

Time frame: At Month 3

Number of Seroprotected Subjects for Anti-polyribosyl-ribitol-phosphate (Anti-PRP) Antibodies.

A seroprotected subject was defined as a vaccinated subject who had anti-PRP antibody concentrations ≥ 0.15 micrograms per milliliter (µg/mL).

Time frame: At Month 3

Number of Subjects With Anti-hepatitis B (Anti-HBs) Antibody Concentration Equal to or Above (≥) 10 and 100 Milli-International Units Per Milliliter (mIU/mL)

A seroprotected subject was defined as a vaccinated subject who had anti-HBs antibody concentrations ≥ 10 mIU/mL. A decrease in the specificity of the anti-HB enzyme-linked immunosorbent assay (ELISA) had been observed in some studies for low levels of antibody (10-100 mIU/mL). All the available blood samples initially tested with ELISA were re-tested using the Chemi Luminescence Immuno Assay (CLIA) approved by the US Food and Drug Administration (FDA). The table shows updated results following partial or complete retesting/reanalysis.

Secondary Outcomes

Concentrations for Anti-diphtheria (Anti-D) and Anti-tetanus (Anti-T) Antibodies.

Concentrations were expressed as geometric mean concentrations (GMCs). The seroprotection cut-off of the assay was 0.1 IU/mL.

Time frame: At Months 0 and 3

Number of Seropositive Subjects for Anti-pertussis Toxoid (Anti-PT) and Anti-pertactin (Anti-PRN) Antibodies.

Time frame: At Months 0 and 3

Concentrations for Anti-polyribosyl-ribitol-phosphate (Anti-PRP) Antibodies.
