Patient Inclusion Criteria

Each participant must meet all of the following criteria during the screening period and at Day 1, unless noted otherwise, to be enrolled in this study: 1. Male or female, 18 years of age or older at the time of consent (Screening Visit, Day 0). 2. Understands and agrees to comply with the study procedures and provides written informed consent. 3. According to the assessment of the investigator, is in good general health and can comply with study procedures. 4. Body mass index (BMI) of 18 kg/m2 to 30 kg/m2 (inclusive) at the Screening Visit (Day 0). 5. Female participants of nonchildbearing potential may be enrolled in the study. Nonchildbearing potential is defined as surgically sterile (history of bilateral tubal ligation, bilateral oophorectomy, hysterectomy) or postmenopausal (defined as amenorrhea for ≥ 12 consecutive months prior to Screening (Day 0) without an alternative medical cause). A follicle-stimulating hormone (FSH) level may be measured at the discretion of the investigator to confirm postmenopausal status. 6. Female participants of childbearing potential may be enrolled in the study if the participant fulfills all the following criteria: - Has a negative pregnancy test at Screening (Day 0) and on the day of the first injection (Day 1). - Has practiced adequate contraception or has abstained from all activities that could result in pregnancy for at least 28 days prior to the first injection (Day 1). - Has agreed to continue adequate contraception through 3 months following the second injection (Day 29). - Is not currently breastfeeding. Adequate female contraception is defined as consistent and correct use of a Food and Drug Administration (FDA) approved contraceptive method in accordance with the product label. For example: - Barrier method (such as condoms, diaphragm, or cervical cap) used in conjunction with spermicide - Intrauterine device - Prescription hormonal contraceptive taken or administered via oral (pill), transdermal (patch), subdermal, or IM route - Sterilization of a female participant's monogamous male partner prior to entry into the study Note: periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. 7. Male participants engaging in activity that could result in pregnancy of sexual partners must agree to practice adequate contraception from the time of the first injection and through 3 months after the last injection. Adequate contraception for male participants is defined as: - Monogamous relationship with a female partner using an intrauterine device or hormonal contraception (described above) - Use of barrier methods and spermicide - History of surgical sterilization - Male participants with partners who have become pregnant prior to Screening are eligible to participate in the study.

Patient Exclusion Criteria

Participants meeting any of the following criteria at the Screening Visit (Day 0) or at Day 1, unless noted otherwise, will be excluded from the study: 1.

Pregnant or breastfeeding. 4. Is acutely ill or febrile 24 hours prior to or at the Screening Visit (Day 0). Fever is defined as a body temperature ≥ 38.0°C/100.4°F. Participants meeting this criterion may be rescheduled within the relevant window periods. Afebrile participants with minor illnesses can be enrolled at the discretion of the investigator. 5. Prior administration of an investigational CoV (eg, SARS-CoV-2, SARS-CoV, MERS-CoV) vaccine. 6. Current treatment with investigational agents for prophylaxis against COVID-19. 7.

Received systemic immunosuppressants or immune-modifying drugs for >14 days in total within 6 months prior to the Screening Visit (Day 0) (for corticosteroids ≥ 20 mg/day of prednisone equivalent). Topical tacrolimus is allowed if not used within 14 days prior to the Screening Visit (Day 0). 21. Anticipating the need for immunosuppressive treatment at any time during participation in the study. 22. Positive serology for hepatitis B virus surface antigen, hepatitis C virus antibody, or human immunodeficiency virus (HIV) type 1 or 2 antibodies identified at the Screening Visit (Day 0). 23. History of anaphylaxis, urticaria, or other significant AR requiring medical intervention after receipt of a vaccine. 24. Bleeding disorder considered a contraindication to IM injection or phlebotomy. 25. Diagnosis of malignancy within previous 10 years (excluding non-melanoma skin cancer). 26. Has received or plans to receive a licensed vaccine ≤ 28 days prior to the first injection (Day 1) or plans to receive a licensed vaccine within 28 days before or after any study injection. Licensed influenza vaccines may be received more than 14 days before or after any study injection. 27. Receipt of systemic immunoglobulins or blood products within 3 months prior to the Screening Visit (Day 0) or plans for receipt during the study. 28. Has donated ≥ 450 mL of blood products within 28 days prior to the Screening Visit (Day 0) or plans to donate blood products during the study. 29. Participated in an interventional clinical study within 28 days prior to the Screening Visit (Day 0) or plans to do so while participating in this study. 30.
