GMCs of anti-diphtheria, anti-tetanus, anti-poliovirus types 1, 2, and 3, anti-haemophilus influenzae type b (anti-PRP) vaccines were measured as: anti-diphtheria, anti-tetanus by ECL assay, anti-poliovirus types 1, 2, and 3 by neutralization assay and anti-Haemophilus influenzae type b (anti-PRP) by Farr-type RIA. Response rate was defined as percentage of participants who achieved: anti diphtheria and anti-tetanus antibody concentrations \>=0.01 international units (IU)/milliliter (mL), \>=0.1 IU/mL and \>=1.0 IU/mL; anti-poliovirus types 1, 2, and 3 antibody titers \>=1:8; anti-PRP antibody concentrations \>=0.15 microgram (mcg)/mL and \>=1 mcg/mL. Percentages are rounded off to the tenth decimal place.

GMCs of anti-measles and anti-rubella antibodies were measured by bulk IgG EIA and anti-mumps antibodies were assessed by ELISA. Vaccine response against anti-measles, anti-mumps, anti-rubella antibodies were defined as percentage of participants with anti-measles, anti-mumps, anti-rubella antibody concentration that met the respective mentioned criterion: measles: \>=255 mIU/mL; mumps: \>=10 mumps antibody units/mL and rubella: \>=10 IU/mL. Percentages are rounded off to the tenth decimal place.
