Three hundred sixty children were tested for pertussis serology 0.5 to 1.58
months after complete whole-cell pertussis vaccination. An immunoblot assay
was used to detect serum antibodies to pertussis toxin, filamentous
hemagglutinin, adenylate cyclase-hemolysin, and pertactin, and
agglutination was used for detection of anti- agglutinogen antibodies.
Antibodies against pertussis toxin, pertactin, and agglutinogens decreased
rapidly after vaccination but increased secondarily, suggesting exposure to
infected persons. In contrast, anti- filamentous hemagglutinin antibodies
persisted and anti-adenylate cyclase-hemolysin antibodies increased
continuously, suggesting either cross-reaction with non-Bordetella antigens
or exposure to Bordetella isolates expressing these two antigens, including
Bordetella pertussis. These data suggest that unrecognized pertussis is
common in France despite massive and sustained immunization in infants and
that vaccinated children become susceptible to infection more than 6 years
after their last vaccination.
