A Study to Compare LBVD to Eupenta and Imovax Polio in Healthy Adults

• DTP-HepB-IPV-Hib vaccine (Biological): Hexavalent vaccine (DTP-HepB-IPV-Hib vaccine: Diphtheria-Tetanus-Pertussis-Hepatitis B-Inactivated Poliovirus-Haemophilus influenzae type b vaccine)
• DTP-HepB-Hib vaccine & IPV (Biological): Pentavalent vaccine (DTP-HepB-Hib vaccine: Diphtheria-Tetanus-Pertussis-Hepatitis B-Haemophilus influenzae type b vaccine)+ IPV(Inactivated poliovirus vaccine)

Primary outcomes

• 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 14 days after the vaccination [Day 1-15]]: Solicited adverse events are classified into the local(pain, tenderness, erythema/redness, induration/swelling) and systemic(fever, fatigue, chills/shivering, myalgia, headache, arthralgia, decreased appetitie, diarrhea, nausea/vomiting, rash) signs and symptoms.
• Number of subjects with any 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 immediate reactions after vaccination with the study vaccine and the solicited adverse events.

Secondary outcomes

• Proportions of the subjects who have shown 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, 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, Pertussis, Polio, Hepatitis B, and Haemophilus influenzae type b
