V114-022

• To evaluate the safety and tolerability of 3 doses of V114 and 3 doses of Prevnar 13™ with respect to the proportion of participants with adverse events (AEs) within each vaccination Group.
• To evaluate the serotype-specific immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) at 30 days following the 3rd dose of V114 and following the 3rd dose of Prevnar 13™within each vaccination Group.

• To evaluate the safety and tolerability of PNEUMOVAX™23 (administered 12 months after allo-HSCT) following 3 doses of V114 and following 3 doses of Prevnar 13™) with respect to the proportion of participants with AEs within each vaccination Group.
• To evaluate the safety and tolerability of a 4th dose of V114 and a 4th dose of Prevnar 13™ (both administered 12 months after allo-HSCT) with respect to the proportion of participants with AEs within each vaccination group
• To evaluate the serotype-specific opsonophagocytic activity (OPA) Geometric Mean Titers (GMTs) at 30 days following the 3rd dose of V114 and following the 3rd dose of Prevnar 13™ within each vaccination Group.
• To evaluate the serotype-specific opsonophagocytic activity (OPA) Geometric Mean Titers (GMTs) at 30 days following the 3rd dose of V114 and following the 3rd dose of Prevnar 13™ within each vaccination Group.
