Outcomes
Primary Outcomes
Number of Seroprotected Subjects Against Diphteria Toxoid (D) and Tetanus Toxoid (T)
Time Frame: At Month 3
A seroprotected subject was defined as a vaccinated subject with anti-D and anti-T antibody concentrations higher than or equal to (≥) 0.1 international units per milliliter (IU/mL).
Number of Seroprotected Subjects Against Polyribosyl-ribitol Phosphate (PRP)
Time Frame: At Month 3
A seroprotected subject was defined as a vaccinated subject with an anti-PRP antibody concentration higher than or equal to (≥) 0.15 microgram/milliliter (µg/mL).
Number of Subjects With a Vaccine Response to Pertussis Toxoid (PT), Filamentous Haemagglutinin (FHA) and Pertactin (PRN) Antibodies
Time Frame: At Month 3
The vaccine response was defined as it follows: * for PT and FHA, an antibody concentration higher than or equal to (≥) 20 EL.U/mL at post-vaccination; * for PRN, at least a 4-fold increase in antibody concentration from pre-vaccination to post-vaccination time points.
Secondary Outcomes
- Number of Subjects With Anti-PRP Antibody Concentrations ≥ 1.0 µg/mL(At Month 3)
- Concentrations for Anti-D and Anti-T Antibodies(At Month 0 and Month 3)
- Concentrations for Anti-PRP Antibodies(At Month 0 and Month 3)
- Concentrations for Anti-PT, Anti-FHA and Anti-PRN Antibodies(At Month 3)
- Number of Subjects With Any and Grade 3 Solicited Local Symptoms(During the 4-day (Day 0-3) follow-up period after each vaccine dose and across doses)
- Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms(During the 4-day (Day 0-3) follow-up period after each vaccine dose and across doses)
- Number of Subjects With Unsolicited Adverse Events (AEs)(During the 31-day (Day 0-30) follow-up period after each vaccination)
- Number of Subjects With Serious Adverse Events (SAEs)(From receipt of first dose of study vaccine (Day 0) to study end (Month 3))
