Arm && Interventions

Group	Intervention	Description
Control group	DTaP-HepB-IPV-Hib vaccine	DTaP-HepB-IPV-Hib vaccine
Test group	DTaP-HepB-IPV-Hib vaccine	DTaP-HepB-IPV-Hib vaccine

Primary Outcome Measures

Name	Time	Method
Number of subjects with serious adverse events	For 181 days (+7 days of window period) after the vaccination [Day 1-181]	serious adverse events that occur after the ICF is obtained until 6 months after vaccination.
Number of subjects with unsolicited adverse events	For 28 days (+7 days of window period) after the vaccination [Day 1-29]	Unsolicited adverse events mean all the adverse events excluding the solicited adverse events that occur after the ICF is obtained until 28 days after vaccination.
Number of subjects with immediate reactions	For 30 minutes after the vaccination	Immediate reactions after vaccination with the study vaccine mean all the signs and symptoms occurring within 30 minutes after the vaccination.
Number of subjects with solicited adverse events	For 7 days after the vaccination [Day 1-8]	Solicited adverse events are classified into the local(pain, tenderness, erythema/redness, induration/swelling, pruritus) and systemic(fever, fatigue, chills/shivering, myalgia, headache, arthralgia, decreased appetite, diarrhea, nausea/vomiting, hypersensitivity) signs and symptoms.

Secondary Outcome Measures

Name	Time	Method
Proportions of the subjects who meet seroprotection/vaccine-response to each antigen and the subjects who have shown seroconversion 28 days post-vaccination with the study vaccine (Day 29) compared to pre-vaccination.	Day 29 (+7 days window period)	Immunogenicity of each components (antibodies against Diphtheria, Tetanus, Acellular Pertussis, Polio, Hepatitis B, and Haemophilus influenzae type b)
GMC or GMT values for each antigen prior to and 28 days post-vaccination with the study vaccine (Day 29)	Day 29 (+7 days window period)	Immunogenicity of each components (antibodies against Diphtheria, Tetanus, Acelluar Pertussis, Polio, Hepatitis B, and Haemophilus influenzae type b
Proportion of the subjects who meet one of the following regarding anti-PT, anti-FHA, and anti-PRN	Day 29 (+7 days window period)	①If the antibody concentration is \< 4 X LLOQ before the administration of the investigational vaccine: The antibody concentration is ≥ 4 X LLOQ 29 days after the administration of the investigational vaccine; ②If the antibody concentration is ≥ 4 X LLOQ before the administration of the investigational vaccine: The antibody concentration 29 days after the administration of the investigational vaccine is ≥ the antibody concentration before the administration
