The antibody response of 67 splenectomized adults and adolescents with benign underlying diseases to a 14‐valent pneumococcal capsular polysaccharide vaccine was determined by an enzyme‐linked immunosorbent assay. It was not significantly different from that of 12 healthy non‐splenectomized adult volunteers for 13 of the 14 polysaccharide antigens studied. Residual splenic tissue as detected by Tc‐scintigraphy was without any influence on the vaccination response. In comparison 5 untreated splenectomized adults with malignant diseases and 11 splenectomized adults receiving immunosuppressive therapy exhibited a significantly reduced combined geometric mean of their postvaccination antibody concentrations (all 14 antigens added) and of their combined geometric mean antibody fold increase as compared to the healthy non‐splenectomized adults. The reduction in antibody response was most pronounced in the group of immunosuppressed patients. Immunogenicity of each of the 14 vaccine antigens varied considerably as judged by the geometric means of the postvaccination arbitrary antibody concentrations. Also individual variation in postvaccination antibody concentration against each antigen was large.
