Posttransplant vaccination case histories with individualized and autopopulated vaccination schedules shown for 3 different cases (white boxes). Case 1: a 19-year-old adolescent underwent allogeneic BMT on March 15, 2016, for leukemia, did not develop chronic GVHD, and on September 15, 2016, at 6 months posttransplant had an unsupported immunoglobulin G (IgG) level of 780 mg/dL. She was varicella zoster virus (VZV) seropositive pretransplant. (A) Her schedule for beginning inactivated vaccines at 6 months posttransplant highlights age-related considerations for HPV vaccine (FAQ 10) as well as when to offer conjugated quadrivalent and group B meningococcal vaccines (FAQ 14). (B) Live vaccines are considered at 2 years posttransplant. Case 2: a 59-year-old man underwent nonmyeloblative allogeneic transplant for chronic lymphocytic leukemia on October 14, 2015, but received rituximab early after transplant, and thus early vaccination at 6 months was not considered appropriate (FAQ 1; Figure 2). He was VZV-seropositive pretransplant. Posttransplant, his last dose of intravenous immunoglobulin (IVIG) was at 11 months, when his B-cell count was 80/μL and serum IgG 665 mg/dL. (C) On October 14, 2016, he began
