Menno R. van den Bergh, MD, Department of Paediatric Immunology and Infectious Disease, University Medical Center, Utrecht, and the Department of Paediatrics of the Spaarne Hospital, Hoofddorp, Netherlands, presented the results here on May 7. Vaccines were given when the infants were aged 2, 3, and 4 months. Noninferiority of group 2 versus group 1 was demonstrated for protein D against all vaccine pneumococcal serotypes except 18C. For each vaccine pneumococcal serotype including 18C, percentages of infants reaching enzyme-linked immunosorbent assay (ELISA) 0.2 mcg/mL were in the same ranges for both PHiD-CV groups. For each vaccine group pneumococcal serotype including 18C, the percentages of infants reaching 33F-ELISA 0.2 mcg/mL and percentages reaching an opsonophagocytic activity titre of 8 were in the same ranges for both treatment groups. The lower antibody geometric mean concentrations for serotype 18C could be related to observed differences in anti-tetanus response, which were higher in group 1. Funding for this study was provided by GlaxoSmithKline. [Presentation title: Immunogenicity of PHiD-CV 3-Dose Primary Vaccination Co-Administered With Pediacel or Infanrix Hexa in the Netherlands.
