Δ Most experts recommend that the second dose of PPSV23 be administered at least 5 years after the first. However, for children with sickle cell disease, some experts recommend an interval of 3 years between the first and second PPSV23. Refer to UpToDate content on management of sickle cell disease for details. The United States Advisory Committee on Immunization Practices recommends a total of two doses of PPSV23 for immunocompromised children at high risk for IPD, including asplenia. However, other experts suggest that individuals with asplenia receive PPSV23 every 5 years. Refer to UpToDate content on prevention of sepsis in the asplenic patient for additional information.
