Immunogenicity and Safety of a DTwP-HepB-Hib-IPV (Shan6™) Vaccine When Administered Concomitantly With Routine Pediatric Vaccines in Healthy Infants and Toddlers in Thailand

Primary Objective:

To demonstrate the non-inferiority of the SHAN6™ vaccine to the licensed SHAN5™ given with bOPV and IPV vaccines when coadministered with PCV and ORV

Secondary Objective:

  • To describe the immunogenicity profile of the SHAN6™ vaccine 3-dose primary infant vaccination and that of the control vaccines (SHAN5™ given with bOPV and IPV)
  • To describe the immune response to co-administered ORV-1 (Rotarix™) in a subset of participants from each group
  • To describe the immune response to co-administered PCV-13 (Prevnar 13®) in a subset of participants from each group
  • To describe the persistence of the antibodies against SHAN6™ antigens following a 3-dose primary series of SHAN6™ or SHAN5™ given with bOPV and IPV
  • To describe the immunogenicity profile of SHAN6™ 28 days after the single booster dose of SHAN6™
  • To describe the safety profile of the SHAN6™ vaccine and the control vaccines (SHAN5™ given with bOPV and IPV), when administered concomitantly with routine pediatric vaccines

  • Moderate or severe acute illness/infection (according to the Investigator's judgment) on the day of vaccination or febrile illness (axillary temperature ≥ 38.0 C). A prospective participant should not be included in the study until the condition has resolved or the febrile event has subsided
