Invasive pneumococcal disease in children with sickle cell disease in the pneumococcal conjugate vaccine era.

Invasive pneumococcal disease (IPD) in children with sickle cell disease (SCD) can be devastating. We sought to assess the impact of IPD in children with SCD since licensure of the pneumococcal conjugate vaccines (PCVs). We found 11 cases of IPD giving an incidence of 417 per 100,000 person-years, much higher than that reported in children without SCD.
