This study will determine whether participants who receive the vaccine V419 at 2, 3, 4, and 12 months of age have an acceptable immune response to the vaccine. The study will also determine whether the immune response to V419 is similar to that of participants who receive a licensed vaccine control.

V419 (Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed, Inactivated Poliovirus, Haemophilus b Conjugate \[Meningococcal Outer Membrane Protein Complex\], and Hepatitis B \[Recombinant\] Vaccine) 0.5 mL intramuscular injection at 2, 3, 4, and 12 months of age.
INFANRIX™ hexa 0.5 mL intramuscular injection at 2, 3, 4, and 12 months of age.

Percentage of Participants Vaccinated With PR5I With Acceptable Antibody (Ab) Response to Haemophilus Influenzae Type b, Diphtheria, Tetanus, and Poliovirus Types 1, 2 & 3, at 5 Months
Antibody titres in the PR5I group were measured by Radioimmunoassay (RIA) for Haemophilus influenzae type b (PRP), Micrometabolic inhibition test (MIT) for diphtheria \& poliovirus, and Enzyme-Linked Immunosorbent Assay (ELISA) for tetanus. Percentage of participants with an Ab titre ≥0.15 μg/mL for Haemophilus influenzae type b (Hib) (polyribosylribitol phosphate, PRP); ≥0.01 IU/mL; for diphtheria \& tetanus; ≥8 (1/dil) for inactivated poliovirus types 1, 2 \& 3 (IPV1, 2 \& 3) are reported. 95% confidence interval (CI) were calculated based on the exact binomial method by Clopper and Pearson. The immune response to PR5I vaccine was considered as acceptable if the lower bounds of the 2-sided 95% CI for the response rates were greater than the predetermined lower CI limits for PRP, diphtheria (80%), tetanus (90%), and IPV1, 2 \& 3 (90%).
Time frame: One month after post-dose 3 of PRI5 (5 months old)
Percentage of Participants Vaccinated With PR5I With Acceptable Ab Response or Seroresponse Rates to All Antigens Contained in the PR5I Vaccine One Month After the Toddler Dose at 13 Months
Antibody titres in the PR5I group were measured by RIA for PRP, MIT for diphtheria \& poliovirus, enhanced Chemiluminescence assay (ECi)) for Hepatitis B surface antigen (HBsAg) and ELISA for tetanus, Pertussis toxoid (PT), Filamentous haemagglutinin (FHA), Fimbriae types 2 \& 3 (FIM) \& Pertactin (PRN). Percentage of participants with an Ab titre ≥1.0 μg/mL for Hib (PRP); ≥0.1 IU/mL; for diphtheria \& tetanus; ≥10 mIU/mL HBsAg; ≥8 (1/dil) for IPV1, 2 \& 3, and seroresponse to PT, FHA, FIM and PRN are reported. 95% confidence interval (CI) were calculated based on the exact binomial method by Clopper and Pearson. The immune response to PR5I vaccine was considered as acceptable if the lower bounds of the 2-sided 95% CI for the response rates were greater than the lower CI limits for PRP, PT, FHA, FIM, and PRN (75%); Diphtheria (80%); HBsAG, IPV 1, 2, 3 (90%).
Time frame: One month after Toddler dose of PRI5 (13 months old)

Prevenar 13 0.5 mL intramuscular injection at 2, 3, 4,and 13 months of age
ProQuad™ 0.5 mL subcutaneous injection at 12 and 13 months of age
Antibody titres were measured by RIA for PRP, MIT for diphtheria \& poliovirus, and ELISA for tetanus. Percentage of participants with an Ab titre ≥0.15 μg/mL for Hib) (PRP); ≥0.01 IU/mL; for diphtheria \& tetanus; ≥8 (1/dil) for inactivated poliovirus types 1, 2 \& 3 (IPV1, 2 \& 3) are reported. The estimated response rates are based on the method by Miettinen and Nurminen stratified by country.
Time frame: One month after post-dose 3 of PRI5 (5 months old)
Percentage of Participants Vaccinated With PR5I Compared With INFANRIX™ Hexa With Acceptable Ab Response Rates to Hepatitis B and Seroresponse to Pertussis Antigens Pt, FHA and PRN One Month After the Toddler Dose at 13 Months Old
Antibody titres were measured by ECi for HBsAg and ELISA for PT, FHA, \& PRN. Percentage of participants with an Ab titre ≥10 mIU/mL HBsAg; ≥8 (1/dil) for IPV1, 2 \& 3, and seroresponse to PT, FHA, and PRN are reported. The estimated response rates are based on the method by Miettinen and Nurminen stratified by country.
Time frame: One month after Toddler dose of PRI5 (13 months old)
Percentage of Participants Vaccinated With PR5I With Acceptable Ab Response to Measles, Mumps, Rubella and Varicella One Month After the Toddler Dose of ProQuad at 13 Months Old
Ab titres were measured by ELISA, excepting the Ab to varicella which was determined by glycoprotein ELISA. Percentage of participants with an Ab titre ≥255 mIU/mL for measles, ≥10 Ab units/mL for mumps, ≥10 IU/mL for rubella, and ≥5 gpELISA units/mL for varicella are reported. 95% CI were calculated based on the exact binomial method by Clopper and Pearson. The immune response to ProQuad vaccine was considered as acceptable if the lower bounds of the 2-sided 95% CI for the response rates were greater than the predetermined lower CI limits: 90% for measles, mumps \& rubella, and 76% for varicella.
Time frame: One month after Toddler dose of PRI5 (13 months old)
Percentage of Participants Vaccinated With PR5I Compared With INFANRIX™ Hexa With Acceptable Ab Response to Measles, Mumps, Rubella and Varicella One Month After the Toddler Dose of ProQuad at 13 Months Old

Time frame: One month after Toddler dose of PRI5 (13 months old)
Percentage of Participants With Injection-site and Systemic Adverse Events (AEs) From Day 1 to Day 15 After Any Vaccination
Global safety was assessed by measuring injection-site and systemic AEs reported daily on the Vaccination Report Card (VRC) by the parent(s) or legal representative from Day 1 to Day 15 (D1-D15) after each hexavalent vaccination. Solicited injection-site and systemic AEs were reported daily from Day 1 to Day 5 (D1-D5) after each hexavalent vaccination. AEs at injection sites were always considered as vaccine-related (Injection-Site Reactions (ISRs)). The investigator assessed whether systemic AEs were related (V-related) or not to the vaccine. All AEs (related and unrelated) are reported.
Time frame: Day 1 to Day 15 after any vaccination
Percentage of Participants Reporting Solicited ISRs From Day 1 to Day 5 After Any Vaccination
Solicited ISRs were defined as injection-site erythema, injection-site pain, and injection-site swelling occurring from Day 1 (D1) to Day 5 (D5) after vaccination. AEs at injection sites were always considered as vaccine-related (Injection-Site Reactions (ISRs)).
Time frame: Day 1 to Day 5 after any vaccination
Percentage of Participants Reporting Unsolicited ISRs From Day 1 to Day 15 After Any Vaccination
Unsolicited ISRs with incidence ≥1% after any vaccination were reported daily on the VRC by the parent(s) or legal representative from (D1-D15). AEs at injection sites were always considered as vaccine-related ISRs
Time frame: Day 1 to Day 15 after any vaccination
Percentage of Participants Reporting Solicited Systemic AE From Day 1 to Day 5 After Any Vaccination
Solicited systemic AEs were defined as crying, decreased appetite, irritability, pyrexia (rectal temperature ≥38.0°C), somnolence, and vomiting occurring from D1 to D5 after vaccination. The investigator assessed whether these systemic AEs were related or not to the vaccines. All (related and unrelated) AEs are reported.
Time frame: Day 1 to Day 5 after any vaccination
