High Rates of Seroprotection and Seroconversion to Vaccine-Preventable Infections in the Early Post–Autologous Stem Cell Transplant Period.

In patients early post–autologous stem cell transplant, seroprotection rates were high for Hemophilus influenzae type B and tetanus toxoid (70%–90%) but lower for Streptococcus pneumoniae (30%–50%) including after revaccination. There were high rates of seropositivity (67%–86%) to measles, mumps, and rubella and varicella zoster virus. Durability of protection requires assessment. [ABSTRACT FROM AUTHOR]
