title: Assessment of the compatibility of co-administered 7-valent pneumococcal conjugate, DTaP.IPV/PRP-T Hib and hepatitis B vaccines in infants 2-7 months of age.
abstract: This study assessed compatibility of concurrently administered 7-valent pneumococcal conjugate (PCV7), hepatitis B (HB) and DTaP.IPV/Hib vaccines. Infants were given DTaP.IPV/Hib and HB at 2, 4, 6 months and randomly assigned (2:1) to receive PCV7 concurrently or sequentially (at 3, 5, 7 months). Antibody levels were compared in 246 concurrent and 122 sequential vaccinees. Responses to PCV7, DTaP.IPV/Hib and HB were generally unaltered with concurrent administration except that Hib responses were increased (p=0.008) and HB responses were reduced (p=0.006) with concurrent dosing, the latter possibly from same thigh injection with DTaP.IPV/Hib. We conclude that PCV7, DTaP.IPV/Hib and HB are compatible with concurrent, separate injections.
