Study Summary

Primary objectives: * To assess the safety profile of each SP0202 formulation and Prevnar 13 in toddlers and infants (after each and any injection). * To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after the administration of one dose in toddlers (Groups 1-4) * To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after the administration of 3 doses in infants (Groups 5-8) * To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after administration of a 4-dose schedule in infants (Groups 5-8) Secondary objectives: * To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after the administration of one dose in toddlers (Groups 1-4) * To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after the administration of 3 doses in a subset of infants (Groups 5-8) * To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after administration of a 4-dose schedule in a subset of infants (Groups 5-8) * In toddlers: to describe the Ab responses against Pentacel antigens before and 1 month following injection of Pentacel * In infants: to describe the Ab responses against antigens of the routine pediatric vaccines (Pentacel, RotaTeq, ENGERIX-B, M-M-RII, and VARIVAX) when administered concomitantly with either SP0202 or Prevnar 13 (at pre-Dose 1 (as applicable) for RotaTeq, Diphteria, Tetanus and Pertussis antigens; at PD3 for ENGERIX-B, RotaTeq, and Pentacel; at PD4 for M-M-RII and VARIVAX\])

Primary Outcome

An AE was any untoward medical occurrence in a participant or in a clinical investigation participant administered a medicinal product and which did not necessarily have a causal relationship with this treatment. Immediate events were recorded to capture medically relevant unsolicited systemic AEs (including those related to the product administered) that occurred within the first 30 minutes after vaccination. An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in
