[The safety and immunogenicity of an heptavalent pneumococcal polysaccharide conjugate vaccine (Prevenar) administered in association with a whole-cell pertussis-based pediatric combination vaccine (DTP-IPV/PRP-T) to French infants with a two-, three-, and four-month schedule].

Unlabelled: Invasive pneumococcal disease is presently a leading cause of mortality due to bacterial infectious diseases in French children less than 2 years of age, and only the pneumococcal conjugate vaccines induce a protective immune response for those within this vulnerable age group.

Material And Methods: The safety and immunogenicity of a heptavalent pneumococcal polysaccharide conjugate vaccine (PREVENAR was tested in French infants immunized with the 2, 3 and 4 month French schedule as part of an open, randomized, comparative clinical study, in association with a whole-cell pertussis-based pediatric combination vaccine.

Results: In the PREVENAR plus DTP-IPV/Hib association group, 90.
