Purpose

This is a 4 dose study with 124 participants (7 adults ,117 children). Adults are considered to be participants 18 years of age or older. Participants are going to be enrolled based on conditions that make them immunocompromised. Participants are going to be followed up for 6 months after dose 4, and each participant is projected to be on the study for approximately 15 months. This study will be conducted in the United States, Brazil, Germany and Mexico.

Participants who are immunocompromised by virtue of the following: - Having known non-small cell lung cancer (NSCLC) and is ≥18 years of age with at least 1 of the following: - Who received chemotherapy at least 2 weeks (14 days) before enrollment (or is treatment naïve), and is not expected to receive chemotherapy within at least 2 weeks (14 days) after dose administration; and/or - Receiving checkpoint inhibitor treatment (programmed cell death protein 1 (PD-1)/ programmed death-ligand 1 (PD-L1) inhibitor, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitor) and has undergone at least 1 treatment cycle prior to enrollment (at Visit 1); or - Receiving targeted drug therapy treatment (epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), proto-oncogene tyrosine-protein kinase (ROS1), v-raf murine sarcoma viral oncogene homolog B1 (BRAF),rearranged during transfection (RET),hepatocyte growth factor receptor (MET), neurotrophic tyrosine kinase (NTRK) inhibitors) and has undergone at least 1 treatment cycle prior to enrollment (at Visit 1); or - Having known chronic lymphocytic leukemia (CLL) and is ≥18 years of age with at least 1 of the following: - Has asymptomatic disease (eg, Rai stage <3, Binet stage A or B) and is undergoing observation and does not receive any treatment for CLL; or - Receiving B-cell inhibitory monoclonal antibody treatment (anti-CD20) and has received at least 3 cycles prior to enrollment; and/or - Receives a Bruton tyrosine kinase (BTK) inhibitor, phosphoinositide 3-kinase (PI3K) inhibitor, or B-cell lymphoma-2 (BCL-2) inhibitor; or - Is currently undergoing maintenance hemodialysis treatment secondary to end-stage renal disease and is ≥18 years of age; or - Is on active immunomodulator therapy (eg, tumor necrosis factor alpha (TNFα) inhibitor, or tofacitinib or methotrexate) for an autoimmune or inflammatory disease disorder (eg, inflammatory arthritis, such as rheumatoid arthritis, psoriatic arthritis, and juvenile idiopathic arthritis, and inflammatory bowel disease, such as ulcerative colitis and Crohn's disease) at a stable* dose *Stable dose is defined as receiving the same dose for at least 3 months (84 days) with no changes in the 28 days prior to Visit 1; or - Receiving a solid organ transplant at least 3 months (84 days) prior to enrollment (Visit 1) and with no acute rejection episodes within 2 months (60 days) prior to enrollment (Visit 1), and is ≥2 to <18 years of age; or - Has had an autologous or allogenic bone marrow or stem cell transplant at least 6 months (182 days) prior to enrollment (Visit 1), with adequate immune reconstitution for immunization, in the investigator's opinion, and is ≥2 to <18 years of age 7. The participant or participant's parent(s)/legal guardian is capable of giving signed informed consent, and assent (as appropriate), which includes compliance with the requirements and restrictions listed in the ICD and in this protocol. The investigator, or a person designated by the investigator, will obtain written informed consent (and assent, as appropriate) from each study participant or participant's parent(s)/legal guardian before any study-specific activity is performed. All parent(s)/legal guardians should be fully informed, and participants should be informed to the fullest extent possible, about the study in language and terms they are able to understand. The investigator will retain the original copy of each participant's signed consent (and assent, as appropriate) document(s).

Exclusion Criteria

  1. Past clinical (based on COVID-19 symptoms/signs alone, if a SARS-CoV-2 NAAT result was not available) or microbiological (based on COVID-19 symptoms/signs and a positive SARS-CoV-2 NAAT result) diagnosis of COVID-19, or a past clinical diagnosis of multisystem inflammatory syndrome in children (MIS-C). 2. Participants with active graft-vs-host disease (GVHD), transplant rejection, or posttransplant lymphoproliferative disorder (PTLD), or participants who have had treatment for these conditions within 3 months (84 days) prior to study enrollment (Visit 1). 3. Participants <18 years of age whose weight is less than the 5th percentile of age-adjusted ideal body weight. 4. Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study. 5. History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (eg, anaphylaxis) to any component of the study intervention(s). 6. Bleeding diathesis or condition associated with prolonged bleeding that would, in the opinion of the investigator, contraindicate intramuscular injection. 7. Participant who is pregnant or breastfeeding. 8. Participants who may be ineligible because of the number of phlebotomy assessments during this study, in the opinion of the investigator. 9. Participants who do not have adequate deltoid muscle mass to allow intramuscular vaccination, in the opinion of the investigator. 10. Previous vaccination with any coronavirus vaccine. 11. Ongoing, or history of, treatment with blood/plasma products or immunoglobulins within 3 months (84 days) prior to Dose 1 or planned receipt of these medications prior to Dose 4. 12.
