Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Seroprotected Subjects Against Poliovirus Types 1, 2 and 3	Seroprotection was defined as anti-polio types 1, 2 and 3 antibody titres = 8 effective dose (ED50), for 50% of vaccinated subjects.	One month after booster vaccination (At Month 1)
Primary	Anti-polio Types 1, 2 and 3 Antibody Titers	Antibody titers were presented as geometric mean titers (GMTs).	Prior to booster vaccination (At Month 0)
Primary	Anti-polio Types 1, 2 and 3 Antibody Titers	Antibody titers were presented as geometric mean titers (GMTs).	One month after booster vaccination (At Month 1)
Secondary	Number of Seroconverted Subjects for Anti-polio Types 1, 2 and 3	Seroconversion was defined as: For initially seronegative subjects, antibody titer = 8 ED50 one month after the booster dose. For initially seropositive subjects: antibody titer one month after the booster dose = 4 fold the pre-booster antibody titer. For subjects with pre-booster antibody titer below the highest dilution tested (reciprocal < 8192 ED50): highest dilution tested one month after the booster dose (reciprocal > 8192 ED50).	One month after booster vaccination (At Month 1)
Secondary	Number of Seroprotected Subjects Against Poliovirus Types 1, 2 and 3	Seroprotection was defined as anti-polio types 1, 2 and 3 antibody titres = 8 effective dose (ED50), for 50% of vaccinated subjects.	Prior to booster vaccination (At Month 0)
Secondary	Number of Seroprotected Subjects Against Diphteria (D) and Tetanus (T)	Seroprotection was defined as anti-D and anti-T antibody concentration = 0.1 international units per milliliter (IU/mL).	Prior to (At Month 0) and one month after booster vaccination (At Month 1)
Secondary	Anti-D and Anti-T Antibody Concentrations	Antibody concentrations were presented as geometric mean concentrations (GMCs), expressed in IU/mL.	Prior to (At Month 0) and one month after booster vaccination (At Month 1)
Secondary	Number of Seroprotected and Seropositive Subjects for Anti-hepatitis B (Anti-HBs)	Seropositivity was defined as anti-HBs antibody concentration = 3.3 milli-international units per milliliter (mIU/mL). Seprotection was defined as anti-HBs antibody concentration = 10 mIU/mL. Note that percentage of subjects with concentration = 10 mIU/mL was over-estimated due to the use of in-house assay overestimating concentrations between 10-100 mIU/mL. Accordingly GMCs were also overestimated. A decrease in the specificity of the anti-HB ELISA assay had been observed in some studies for low levels of antibody (10-100 mIU/mL). The table shows updated results following partial or complete retesting/reanalysis. Some of the available blood samples initially tested with ELISA were re-tested using the new assay, CLIA.	Prior to (At Month 0) and one month after the booster vaccination (At Month 1)
Secondary	Anti-HBs Antibody Concentrations	Antibody concentrations were presented as geometric mean concentrations (GMCs), expressed in mIU/mL.	Prior to (At Month 0) and one month after the booster vaccination (At Month 1)
Secondary	Number of Seroprotected Subjects Against Polyribosil-ribitol-phosphate (PRP)	Seprotection was defined as anti-PRP antibody concentration = 0.15 micrograms per milliliter (µg/mL).	Prior to (At Month 0) and one month after booster vaccination (At Month 1)
Secondary	Anti-PRP Antibody Concentrations	Antibody concentrations were presented as geometric mean concentrations (GMCs), expressed in µg/mL.	Prior to (At Month 0) and one month after booster vaccination (At Month 1)
Secondary	Number of Seropositive Subjects for Anti-Bordetella Pertussis (Anti-BPT)	Seropositivity was defined as anti-BPT antibody concentration = 15 enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL).	Prior to (At Month 0) and one month after the booster vaccination (At Month 1)
Secondary	Anti-BPT Antibody Concentrations	Antibody concentrations were presented as geometric mean concentrations (GMCs), expressed in EL.U/mL.	Prior to (At Month 0) and one month after booster vaccination (At Month 1)
Secondary	Number of Subjects With a Booster Response for Anti-BPT	Booster response was defined as: For initially seronegative subjects, antibody concentration = 15 EL.U/mL one month after the booster dose. For initially seropositive subjects: antibody concentration one month after the booster dose = 2 fold the pre-booster antibody concentration.	One month after booster vaccination (At Month 1)
Secondary	Number of Subjects With Any Solicited Local Symptoms	Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.	During the 8-day (Days 0-7) post-vaccination period
Secondary	Number of Subjects With Any Solicited General Symptoms	Assessed solicited general symptoms were drowsiness, irritability, loss of appetite and fever [defined as axillary temperature equal to or above (=) 37.5 degrees Celsius (°C)]. Any = occurrence of the symptom regardless of intensity grade.	During the 8-day (Days 0-7) post-vaccination period
Secondary	Number of Subjects With Any Unsolicited Adverse Events (AEs)	An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.	During the 31-day (Day 0-Day 30) post-vaccination period
Secondary	Number of Subjects With Serious Adverse Events (SAEs)	Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.	During the entire study period (from Month 0 to Month 1)
