Dataset from Immunogenicity and Safety Study of GSK Biologicals' Combined Diphtheria-tetanus-acellular Pertussis-hepatitis B-inactivated Polio-virus and Haemophilus Influenzae Type b Vaccine (Infanrix Hexa™) (217744) in Healthy Infants Born to Mothers Vaccinated With Boostrix™ During Pregnancy or Immediately Post-delivery

The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' Infanrix hexa, given in the primary vaccination schedule to infants born to pregnant women who participated in study 116945 [DTPA (BOOSTRIX)-047]. This study will help us evaluate if the presence of transplacentally transferred maternal antibodies interfere with the immune response to primary vaccination with Infanrix hexa and a co-administered pneumococcal conjugate vaccine given as a part of this study in infants.
