Summary Splenectomy predisposes for invasive pneumococcal disease. We investigated the immune response of splenectomised hereditary spherocytosis (HS) patients upon sequential pneumococcal vaccination. Thirty‐nine HS‐patients (2‐ to 18‐year‐old) had undergone near‐total or total splenectomy. All received one dose of 7‐valent pneumococcal conjugate vaccine (PCV‐7) and 23‐valent‐pneumococcal‐polysaccharide vaccine (PPV‐23) 2 months apart. Pneumococcal antibodies against serotypes 5/6B/7/14/18C/19F/23F and immunoglobulin serum concentrations were determined before PCV‐7 and 4 weeks after PPV‐23. Significant rises in antibody geometric mean concentrations were observed after PCV‐7 except for serotypes 5 and 7, which increased after PPV‐23. We found no impact of the mode of splenectomy.
