NCT00143780

Brief Summary

Streptococcus pneumoniae, also known as Pneumococcus, is a common cause of pneumonia in transplant patients. There has been a vaccine available for this infection called Pneumovax. Recently, a new vaccine for this infection called Prevnar has been developed which may be more effective. Vaccinating the bone marrow donor before transplant may boost the recipient's immune response to the vaccine after transplant. This study is done to compare how vaccinating the donor with one of the vaccines will affect the recipient's immune system response to the vaccine.

Outcome Measures

Primary Outcomes (1)

  • Immunogenicity of two vaccines via a determination of serotype specific capsular antibody formation and functional antibody formation from donor and recipient serum.

Secondary Outcomes (1)

  • All patients will be called by telephone 24 hours after receiving vaccine to determine if any acute adverse events occurred. Any occurance of pneumococcal disease in recipients for one year post-transplant during the study period will be recorded.
