Reporting Groups
  Description
13vPnC Participants received one single 0.5 mL dose of 13-valent pneumococcal conjugate vaccine (13vPnC) coadministered with meningococcal C-tetanus toxoid conjugate vaccine (NeisVac-C) and a combined diphtheria, tetanus, five component acellular pertussis (DT5aP), inactivated poliomyelitis (IPV) and haemophilus influenzae type b (Hib) conjugate vaccine (Pediacel) at the 2- and 4-month visits (infant series). Pediacel was administered without study vaccine at 3-month visit. Participants recieved one single 0.5 mL dose of 13vPnC coadministered with Haemophilus Influenzae Type b (Hib) and Meningococcal C Vaccine (Menitorix) at the 12-month visit (toddler dose).
7vPnC Participants received one single 0.5 mL dose of 7-valent pneumococcal conjugate vaccine (7vPnC) coadministered with meningococcal C-tetanus toxoid conjugate vaccine (NeisVac-C) and a combined diphtheria, tetanus, five component acellular pertussis (DT5aP), inactivated poliomyelitis (IPV) and haemophilus influenzae type b (Hib) conjugate vaccine (Pediacel) at the 2- and 4-month visits (infant series). Pediacel was administered without study vaccine at 3-month visit. Participants recieved one single 0.5 mL dose of 7vPnC coadministered with Haemophilus Influenzae Type b (Hib) and Meningococcal C Vaccine (Menitorix) at the 12-month visit (toddler dose).
