Safety and Immunogenicity of a Pneumococcal Conjugate Vaccine When Administered Concomitantly With Routine Pediatric Vaccines in Healthy Toddlers and Infants

PSK00008

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\])

This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines * Receipt of immune globulins, blood or blood-derived products in the past 3 months * Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months) * History of diphtheria, tetanus, pertussis, poliomyelitis, and/or H. influenzae type b infection or disease Specifically for infants * Receipt of any vaccine in the 4 weeks preceding the study vaccination or planned receipt of any vaccine from enrollment through the last blood sampling Visit (Visit 6), except for influenza vaccination or COVID-19 vaccination, which may be received at least 2 weeks before or 2 weeks after any study vaccination. This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines, and COVID-19 vaccines as applicable per local recommendations * Receipt of immune globulins, blood or blood-derived products since birth. * Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks) since birth * Previous vaccination against S. pneumoniae * Previous vaccination against the following antigens: diphteria, tetanus, pertussis, H. influenzae type b, poliovirus, rotavirus, measles, mumps, rubella, and varicella * Receipt of more than 1 previous dose of hepatitis B vaccine * History of diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, measles, mumps, rubella, varicella, H. influenzae type b, and/or rotavirus infection or disease * History of intussusception The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
