The secondary safety endpoints are the incidence of adverse events (AEs) within 30 minutes after each injection, the incidence of solicited local and systematic AEs in the period of solicitation after each injection, the incidence of unsolicited AEs in 30 days after each injection, the incidence of AEs in 30 days after each injection, and the incidence of serious adverse events in 6 months after administrations.', 'detailedDescription': "This is a randomized, open-labeled, parallel phase IV clinical trial to evaluate the immunogenicity and safety of concomitant administration of sIPV and DTaP or MMR. 2640 participants aged 2 months will be randomly assigned to 4 cohorts in a ratio of 1:1:1:1. \\[Cohort A\\] 660 infants will take administration of sIPV at 2, 3, 4, 18 months of age and DTaP at 2, 4, 6, and 18 months of age. sIPV and DTaP at 2, 4, and 18 months of age will be taken concomitantly. \\[Cohort B\\] 660 infants will take administration of sIPV at 2, 3 months of age, bOPV at 4 months and 4 years of age, and DTaP at 2, 4, 6, 18 months of age. sIPV/bOPV at 2, 4 months of age will be taken concomitantly. \\[Cohort C\\] 660 infants will take administration of sIPV at 2, 3, 4, 18 months of age, DTaP at 2, 4, 6, and 18 months of age, and MMR at 18 months of age. DTaP will be taken 7 days after sIPV at 2, 4, 18 months of age. Half participants will take concomitant administration of sIPV and MMR at 18 months of age, and the rest will take them separately (MMR at 19 months of age). \\[Cohort D\\] 660 infants will take administration of sIPV at 2, 3 months of age, bOPV at 4 months and 4 years of age, and DTaP at 2, 4, 6, 18 months of age.
