ABSTRACT The IgG and IgM class-specific antibody response to PnVx in SCD patients was investigated since pneumococcal infection after PnVx occurs in some SCD patients and since patients with


functional asplenia (including SCD) may not be able to form normal levels of protective antibody and/or switch from IgM to IgG class of antibody in response to certain antigens. Both


normals and SCD patients formed IgG as well as IgM antibody by ELISA to each pneumococcal type tested. The level and predominant class of antibody varied between serotypes. Mean


Fold-increase (log2) in Antibody Titer to PnVx Serotypes: Although statistically significant differences were not found, slightly lower responses were noted in SCD patients, especially to


type 6, a serotype frequently associated with PnVx failure. Further testing in patients with PnVx failure will be necessary to determine if inadequate IgG or IgM response contributes to lack


of protection In these instances. ARTICLE PDF AUTHOR INFORMATION AUTHORS AND AFFILIATIONS * Departments of Pediatrics, University of Florida, Gainesville, and University of California, San
