Inclusion Criteria: * Patients must be \>= 1 and \< 31 years at time of enrollment * Patients must have first relapse of CD19+ B-ALL (relapse blasts must express CD19) in one of the following categories: * Isolated bone marrow relapse * Isolated central nervous system (CNS) (excluding known optic nerve/retinal and CNS chloromas) and/or testicular relapse * Combined bone marrow with extramedullary relapse in the CNS (excluding known optic nerve/retinal and CNS chloromas) and/or testes * Patients with Down syndrome (DS) are eligible in the following categories: * Isolated bone marrow relapse * Combined bone marrow with CNS (excluding known optic nerve/retinal and CNS chloromas) and/or testicular relapse * Patients must have a performance status corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1 or 2. Use Karnofsky for patients \> 16 years of age and Lansky for patients =\< 16 years of age * Of note, for patients with developmental delay (e.g., Down syndrome) regardless of age, Lansky scale may be substituted for Karnofsky scale. However, the requirement for ECOG 0-2 remains, regardless of known history of developmental delay * Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study * Patients with prior blinatumomab or CD19+ chimeric antigen receptor therapy in the upfront setting will be eligible, provided relapsed lymphoblasts retain CD19 expression * Patients must not have had a prior hematopoietic stem cell transplant * A single intrathecal chemotherapy at the time of relapse will be allowed. If \< 7 days have elapsed between this intrathecal therapy (IT) and the start of protocol therapy, then the day 1 intrathecal chemotherapy (i.e. methotrexate, cytarabine, or triple intrathecal) may be omitted * In the 28 days prior to enrollment, up to five days of post-relapse, pre-enrollment therapy (steroids and/or hydroxyurea only) is permissible * Patients with Down syndrome who received pre-enrollment therapy and have a white blood count (WBC) \>= 30,000/ul at the time of enrollment still must receive protocol specified cytoreductive therapy with vincristine and dexamethasone, and no "washout" is required * Patients with Down syndrome who received pre-enrollment therapy and have a WBC \< 30,000/ul at the time of enrollment must be given a 24 hour "washout" before starting immunotherapy * Note: There is no waiting period or "washout" for patients who relapse while receiving upfront therapy * Creatinine clearance or radioisotope glomerular filtration rate (GFR) \>= 70 mL/min/1.73 m\^2 OR a serum creatinine based on age/sex as follows (within 7 calendar days prior to enrollment): * Age: Maximum serum creatinine (mg/dL) * 1 to \< 2 years: 0.6 (male), 0.6 (female) * 2 to \< 6 years: 0.8 (male), 0.8 (female) * 6 to \< 10 years: 1 (male), 1 (female) * 10 to \< 13 years: 1.2 (male), 1.2 (female) * 13 to \< 16 years: 1.5 (male), 1.4 (female) * \>= 16 years: 1.7 (male), 1.4 (female) * The threshold creatinine values in this Table were derived from the Schwartz formula for estimating GFR utilizing child length and stature data published by the Center for Disease Control (CDC) * Shortening fraction of \>= 27% by echocardiogram, or ejection fraction of \>= 50% by echocardiogram, cardiac magnetic resonance imaging (MRI) or radionuclide angiogram * No evidence of dyspnea at rest, no exercise intolerance, and a pulse oximetry \> 94% if there is clinical indication for determination * All patients and/or their parents or legal guardians must sign a written informed consent * All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met Exclusion Criteria: * Patients with B-lymphoblastic lymphoma (B-LLy) * Patients with Burkitt leukemia/lymphoma or mature B-cell leukemia * Patients with Philadelphia chromosome positive (Ph+) B-ALL or ABL class Ph-like B-ALL (i.e. rearrangements involving ABL1, ABL2, CSF1R or PDGFRB and predicted to be sensitive to imatinib or dasatinib) * Patients with mixed phenotype acute leukemia (MPAL) * Patients with known Charcot-Marie-Tooth disease * Patients with known MYC translocation associated with mature (Burkitt) B-cell ALL, regardless of blast immunophenotype * Patients with active, uncontrolled infection defined as: * Positive bacterial blood culture within 48 hours of study enrollment * Receiving IV or PO antibiotics for an infection with continued signs or symptoms. Note: Patients may be receiving IV or oral antibiotics to complete a course of therapy for a prior documented infection if cultures have been negative for at least 48 hours and signs or symptoms of active infection have resolved. For patients with clostridium (C.) difficile diarrhea, at least 72 hours of antibacterial therapy must have elapsed and stools must have normalized to baseline. * Fever above 38.2 degrees Celsius (C) within 48 hours of study enrollment with clinical signs of infection. Fever without clinical signs of infection that is attributed to tumor burden is allowed if blood cultures are negative for \> 48 hours * A positive fungal culture within 30 days of study enrollment or active therapy for presumed invasive fungal infection * Active viral or protozoal infection requiring IV treatment * Patients known to have one of the following concomitant genetic syndromes: Bloom syndrome, ataxia-telangiectasia, Fanconi anemia, Kostmann syndrome, Shwachman syndrome or any other known bone marrow failure syndrome are not eligible. * Patients with uncontrolled HIV, hepatitis B, or hepatitis C infection. Of note, patients with known human immunodeficiency virus (HIV) infection on effective anti-retroviral therapy with undetectable viral load for at least the last 6 months prior to enrollment are eligible. Similarly, hepatitis B and hepatitis C positive patients who have been treated and have no viral detectable burden are also eligible * Patients with significant central nervous system pathology that would preclude treatment with blinatumomab, including history of severe neurologic disorder or autoimmune disease with CNS involvement * Note: Patients with a history of seizures that are well controlled on stable doses of anti-epileptic drugs are eligible Patients with a history of cerebrovascular ischemia/hemorrhage with residual deficits are not eligible. Patients with a history of cerebrovascular ischemia/hemorrhage remain eligible provided all neurologic deficits have resolved * Patients with an active known/suspected autoimmune disease are not eligible. However, patients with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll * Patients with DS patients with known non-hematopoietic, non-CNS/testicular extramedullary disease (i.e., chloromatous disease) are not eligible * Note: Group 3 and 4 patients with known non-hematopoietic, non-CNS/testicular extramedullary disease (i.e., chloromatous disease) are eligible if this is NOT the only site of relapsed disease * Female patients of childbearing potential are not eligible unless a negative pregnancy test result has been obtained within 7 days prior to enrollment. Patients who are sexually active and of reproductive potential are not eligible unless they agree to use an effective contraceptive method for the duration of this study. Men with female partners of childbearing potential should use effective contraception during the duration of their treatment. The effect of blinatumomab on fertility has not been evaluated. Blinatumomab is not recommended for pregnant women or women of childbearing potential (WOCBP) not using contraception. Females of reproductive potential must use effective contraception during treatment and for at least 48 hours after the last dose of blinatumomab. Studies in animal models have shown that nivolumab can adversely impair pregnancy. Thus, nivolumab is expected to cause fetal harm during pregnancy. WOCBP receiving nivolumab must continue contraception for a period of at least 5 months after the last dose of nivolumab. It is unknown whether nivolumab is present in breast milk, thus breastfeeding should be discontinued while a patient is receiving nivolumab * Lactating females are not eligible unless they agree to not breastfeed their infants. It is unknown whether blinatumomab or its metabolites are excreted in human breast milk. Women are not permitted to breastfeed while receiving blinatumomab and for the last 48 hours after the last blinatumomab dose. Due to the potential for serious adverse reactions in the breastfed infant, women are not permitted to breastfeed during treatment and for 5 months after the last nivolumab dose
