BackgroundA survey of National Marrow Donor Program transplant centers in 1995 demonstrated a wide range of immunization practices in post-hematopoietic stem cell transplant (HSCT) recipients, which led to the 2000 Centers for Disease Control and Prevention (CDC) recommendations for vaccination after HSCT. We surveyed the principal investigators of the Pediatric Blood and Marrow Transplant Consortium (PBMTC) to identify immunization practice patterns after HSCT and assess compliance with the 2000 CDC guidelines.ProcedureApproval was obtained from the Medical University of South Carolina Institutional Review Board. A 33 question survey using surveymonkey.com was distributed by email to principal investigators in the PBMTC.ResultsForty-one (40%) of the 102 pediatric HSCT centers participating in the PBMTC responded. Thirty of the responding centers completed the entire survey. For individual vaccines, compliance with the CDC guidelines ranged from 22% to 93%. Less than 20% of the centers reported schedules consistent with the 2000 CDC recommendations for both allogeneic and autologous HSCT recipients.ConclusionDespite the 2000 CDC guidelines, wide variation in post-HSCT immunization practices still exists. Updated guidelines have been needed, particularly to address the use of the pneumococcal conjugate vaccine. In conjunction with multiple other groups, the CDC recently released new immunization guidelines in October 2009. Additional data are still needed to adequately address the utility of incorporating immunologic parameters with the timing of vaccination after HSCT.Copyright 2010 Wiley-Liss, Inc.
