Women of child bearing potential must agree to continued use of contraception throughout the 12 months of study participation. * It is preferable that a patient has access to a "smartphone" or tablet or laptop or desktop computer and/or an email address * In the event that a patient does not have access to any of the above, the patient may complete all follow-up surveys via the study's Call Center or in written form in the offices of the Principal Investigator as specified in the protocol * Documented diagnosis of either hematologic malignancy or solid tumor as identified by standard ICD-10 diagnostic category * Patients may be included with any ONE of the following criteria: * On active treatment for solid tumor or hematologic malignancies. This can include: high-dose corticosteroids (i.e., ≥20 mg prednisone or equivalent per day when administered for ≥2 weeks), as well as any FDA-approved alkylating agents, antimetabolites, transplant-related immunosuppressive drugs, cancer chemotherapeutic agents classified as severely immunosuppressive, tumor-necrosis (TNF) blockers, and other biologic agents that are immunosuppressive or immunomodulatory (e.g., B-cell depleting agents) or any combination of these agents * Hematologic malignancy patients can also be included if he/she is up to 12 months post-treatment and either in remission, stable or progressing as determined by the Investigator * Solid tumor patients can also be included if he/she is up to 6 months post-treatment * Received chimeric antigen receptor (CAR-T) or hematopoietic stem cell transplant (within 1 year of transplantation or taking immunosuppression therapy) * Cancer is progressing as determined by the Investigator * Treatment must have been initiated ≤12 months prior to baseline for all patients, * Concomitant radiation therapy is permitted but cannot be the sole therapy * Have been vaccinated with one or more doses of Janssen, Moderna or Pfizer COVID-19 vaccine * If having been previously diagnosed with SARS-CoV-2 infection, the diagnosis has to be at least 90 days prior to study randomization. If previously diagnosed, previous treatment with Ivermectin or hydroxychloroquine is acceptable. * Have a negative SARS-CoV-2 antigen rapid test performed in the office at screening * Patient willing to receive treatment with AZD7442 600 mg IM or IV * Patient willing to complete baseline and 13 post-enrollment Patient Experience/Clinical Outcome Assessment surveys. * Patient willing to complete baseline and 5 QoL assessments * Patient willing to have blood drawn for serum concentration of AZD7442 9 times post-baseline and repeated if patient becomes COVID-19 positive * Patient willing to have blood drawn for T-cell assay at day 30 post-baseline and repeated if patient becomes SARS-COV-2 RNA by RT-PCR positive * Patient willing to have RBD-IgG drawn at baseline, days 90 and 180 post-baseline and repeated if patient becomes SARS-COV-2 RNA by RT-PCR positive * Patient willing to signed Informed Consent Form * Patient willing to sign Authorization for Release of Health Information (including treating physicians' or other medical personnel's records, medication prescriber records, pharmacy records and medical insurance claims) Exclusion Criteria: * Women who are pregnant, breast feeding or of child bearing potential and not using contraception * Absence of a qualifying type of cancer as defined by standard ICD-10 diagnostic criteria * Treatment initiated \>12 months prior to baseline or were not on active therapy ≤12 months prior to enrollment with FDA approved oral, intramuscular and/or intravenous chemotherapy, immunotherapy, targeted therapy, other therapy or any combination of these agents * Patient receiving only radiation therapy * Patient with an ECOG performance status of 2 or higher * Patient with an expected cancer survival of less than 12 months by disease category * Patient receiving adjuvant endocrine therapy as their only form of therapy for early-stage breast cancer * Solid tumor patients more than 6 months post treatment and their cancer is considered to be stable or in remission as determined by the Investigator * AZD7442 IM administration at any time prior to day of enrollment * AZD7442 IM or IV administration on the same day as the patient receives any IV or IM cancer treatment * Have a positive test for SARS-CoV-2 antigen performed by either Rapid Test or SARS-CoV-2 RNA by RT-PCR (Polymerase Chain Reaction) less than 90 days prior to enrollment * Patient with a prior (within 90 days), current, or planned use of any of COVID-19 convalescent plasma, other monoclonal antibodies against SARS-CoV-2 or any other EUA approved SARS-CoV-2 treatment * Patient with fever \>100.0 F, and/or cough, chills, loss of smell or taste or shortness of breath or any other signs or symptoms consistent with COVID-19 within 5 days prior to enrollment * Patient who has any known active acute respiratory infection * Patient who has persistent (refractory to treatment for ≥14 days) bacterial or fungal infection * Patient who has a past SARS-CoV-2 infection within 90 days prior to randomization * Patient who has received vaccination with any dose of Janssen, Pfizer or Moderna COVID-19 vaccine less than 14 days prior to baseline for this study * Planned use of any investigational, authorized, or approved vaccine for COVID-19 less than 14 days prior to administration of AZD7442 600 mg IM or IV * Patient who is unwilling to have SARS-CoV-2 RBD-IgG antibody levels drawn at least 3 times * Patient who is unwilling to receive treatment with IM or IV AZD7442 * Patient who is unwilling to complete baseline and up to 13 follow-up Experience/Clinical Outcome Assessment (COA) surveys. * Patient who is unwilling to complete baseline and up to 5 QoL assessments * Patient who is unwilling to have blood drawn for AZD7442 serum concentration at least 9 times * Patient who is unwilling to have blood drawn at least once for T-cell assay * Patient whose native language is not English and does not have a person who can translate the regulatory documents, surveys and QoL assessments. * Patient who is unable to provide Informed Consent or Authorization for Release of Health Information due to mental illness that requires a Legally Authorized Representative. * Patient who is legally blind and does not have a witness/caregiver who has agreed to assist the patient in his/her participation in the study. * Patient with a history of a severe allergic reaction (i.e., anaphylaxis) to any of the components of AZD7442 * Patient with a history of severe allergic reaction (hypersensitivity) to any SARS-COV-2 vaccination, Polyethylene Glycol (PEG) or Polysorbate 80 * Patient who is illiterate and does not have a witness/caregiver who has agreed to assist the patient in his/her participation in the study. * Patient who is participating in an interventional trial for prophylaxis or treatment of SARS-CoV-2
