简要总结
The purpose of this study is to 1) evaluate the safety and tolerability, and immunogenicity of blinded V114 and Prevnar 13™ within each vaccination group, and 2) evaluate the safety and tolerability, and immunogenicity of PNEUMOVAX™23 (administered as open label, 12 months after allogeneic hematopoietic stem cell transplant [allo-HSCT] in participants who do not develop chronic graft-versus-host disease [GVHD]).

A serious adverse event (SAE) is an AE that is life-threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgment. The percentage of participants with a vaccine-related SAE following dose 1 (with either V114 or Prevnar 13™) was reported. Vaccine-related SAEs were counted starting after vaccine dose 1 up to 12 months post-HSCT, which could be up to 9 months post-vaccine dose 1.
