Functional Immunity to Cross-Reactive Serotype 6A Induced by Serotype 6B in Pneumococcal Polysaccharide Vaccine
Kyung Hyo Kim
Clin Exp Pediatr. 2005;48(5):506-511.   Published online May 15, 2005
Purpose : Streptococcus pneumoniae serotype 6B and 6A are important pathogens in pneumococcal infections. It is commonly assumed that the 6B vaccines elicit antibodies cross-reacting with the 6A serotype and the cross-reactive antibodies protect against infections of 6A. To examine this assumption, we measured the opsonophagocytic capacity to serotype 6A and 6B in adults. Methods : Twenty-four adults were immunized...
