BACKGROUND:Immunogenicity of the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D-conjugate vaccine (PHiD-CV) was evaluated when coadministered with DTPw-HBV/Hib and OPV at 6, 10, and 14 weeks of age in the Philippines, or with DTPw-HBV/Hib and IPV at 2, 4, and 6 months of age in Poland. METHODS: In this double-blind, controlled study (107007/NCT00344318), 400 Filipino and 406 Polish infants 6 to 12 weeks of age were randomized (3:1) to receive either PHiD-CV or the 7-valent pneumococcal conjugate vaccine (7vCRM). Immune responses were assessed 1 month post-dose III. RESULTS: Percentages of infants with anti-pneumococcal antibody concentrations >or=0.2 microg/mL (GSK's 22F-inhibition ELISA) were within the same range for both pneumococcal conjugate vaccine groups, with the exception of serotypes 6B and 23F for which lower percentages were observed in the PHiD-CV group in Poland. At least 98.2% of PHiD-CV vaccinees had antibody concentrations >or=0.2 microg/mL against pneumococcal serotypes 1, 5, and 7F. In both countries, anti-pneumococcal antibody geometric mean concentrations against serotypes 18C and 19F were higher in the PHiD-CV group than in the 7vCRM group. Antibody geometric mean concentrations for most of the other common serotypes were within the same range for both groups in the Philippines and were lower in the PHiD-CV group in Poland. Functional responses (opsonophagocytic activity [OPA]) were observed for all vaccine serotypes in both countries. CONCLUSIONS: PHiD-CV was immunogenic against each of the 10 pneumococcal vaccine serotypes when coadministered with DTPw-HBV/Hib and poliovirus vaccines.
