Inclusion Criteria:

* DONORS: Documented informed consent of the participant. This can be done in person or informed consent can be obtained remotely.

  * Remote consent, when appropriate, will be obtained per institutional guidelines.
  * Assent, when appropriate, will be obtained per institutional guidelines.
  * Adult subjects who require a legally authorized representative (LAR) will not be permitted to be enrolled under this protocol.
* DONORS: Age: 18 - 75.
* DONORS: Women of childbearing potential (WOCBP): negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
* DONORS: Agreement by females and males of childbearing potential\* to use an effective method of birth control (hormonal or barrier method) or abstain from heterosexual activity prior to study entry and for up to 90 days post-vaccination.

  * Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for \> 1 year (women only).
* RECIPIENTS: Documented informed consent of the participant and/or legally authorized representative. This can be done in person or informed consent can be obtained remotely.

  * Remote consent, when appropriate, will be obtained per institutional guidelines.
  * Assent, when appropriate, will be obtained per institutional guidelines.
  * Adult subjects who require a legally authorized representative (LAR) will not be permitted to be enrolled under this protocol.
* RECIPIENTS: Participant must be willing to comply with study and/or follow-up procedures, including willingness to be followed for one year post-HCT.
* RECIPIENTS: Age: 18 - 75.
* RECIPIENTS: Planned peripheral blood stem cell (PBSC) or bone marrow (BM) HCT for the treatment of the following hematologic malignancies:

  * Lymphoma (Hodgkin and Non-Hodgkin).
  * Myelodysplastic syndrome.
  * Acute lymphoblastic leukemia in first or second remission (for acute lymphoblastic leukemia/lymphoblastic lymphoma, the disease status must be in hematologic remission by bone marrow and peripheral blood. Persistent lymphadenopathy on computed tomography (CT) or CT/positron emission tomography(PET) scan without progression is allowed.)
  * Acute myeloid leukemia in first or second remission.
  * Chronic myelogenous leukemia in first chronic or accelerated phase, or in second chronic phase.
  * Other hematologic malignancies judged appropriate by the clinical principal investigators (PIs), including chronic lymphocytic leukemia, myeloproliferative disorders and myelofibrosis. Patients with multiple myeloma and those with non-malignant disease such as aplastic anemia are excluded\*\*.

    * Adult cases of multiple myeloma (MM) are excluded as HCT is not standard of care for MM and is only performed in very advanced cases with an associated high risk of relapse and non-relapse mortality (NRM). Adults with aplastic anemia are excluded because their standard management includes T cell depletion with agents such as antithymocyte globulin (ATG), which is not permissible on this protocol. Patients undergoing a second haploHCT are not eligible (patients who have undergone a previous autologous HCT are eligible).
* RECIPIENTS: Patients receiving myeloablative (MA) or reduced intensity conditioning (RIC) are allowed.

A unidirectional mismatch in either the graft versus host or host versus graft direction is considered a mismatch. The donor and recipient must demonstrate that they are a full haplotype match by being identical at a minimum of one allele (at high resolution deoxyribonucleic acid \[DNA\]-based typing) at the following genetic loci: HLA-A, -B, -C, and DRB1 if 8 allele typing is used; HLA-A, -B, -C, -DRB1, and -DQB1 if 10 allele typing is used; and HLA-A, -B, -C, -DRB1-, DQB1, and -DPB1 is 12 allele typing is used.
* RECIPIENTS: Planned HCT with minimal to no-T cell depletion of graft.
* RECIPIENTS: Conditioning and immunosuppressive regimens according to institutional guidelines are permitted.

  * Note: To be performed within 45 days prior to day 1 of protocol therapy.

  * Note to be performed within 45 days prior to day 1 of protocol therapy.
* RECIPIENTS: Seronegative for HIV antigen (Ag)/antibody (Ab) combination (combo), hepatitis c virus (HCV)\*, active hepatitis b virus (HBV) (surface antigen negative) and syphilis (RPR) within 2 months of registration and no history of disseminated cutaneous human papillomavirus (HPV) related disease.

  * If seropositive for HIV, HCV or HBV, nucleic acid quantitation must be performed. Viral load must be undetectable.
* RECIPIENTS: Meets other institutional and federal requirements for infectious disease titer requirements.

  * Note Infectious disease testing to be performed within 45 days prior to day 1 of protocol therapy.
* RECIPIENTS: Women of childbearing potential (WOCBP): negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required (to be performed within 45 days prior to day 1 of protocol therapy).
* RECIPIENTS: Agreement by females and males of childbearing potential\* to use an effective method of birth control (hormonal or barrier method) or abstain from heterosexual activity prior to study entry and up to 90 days post-HCT.
