(Any subjects with results that are Grade 2 or above according to toxicity table (modified from FDA Guidance for Industry: Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trial) will be excluded)
10. Subject willing to provide verifiable identification and has means to be contacted and to contact the Principal Investigator (PI) during the study.

Phase 2 Exclusion Criteria:

5. Known to have HIV, HBsAg, or HCV per self-reported medical history
6. Febrile illness with temperature ≥38°C within 7 days of dosing. (Subjects with acute febrile illness within 7 days of dosing may be rescreened no earlier than 7 days following resolution of symptoms).
7. Rapid SARS CoV-2 antigen nasopharyngeal swab is positive on Day 1 prior to dosing or positive SARS-CoV-2 RT-PCR if result is received prior to dosing
8. Female subject who is pregnant or breastfeeding
9. Has previously received any coronavirus vaccine
10. Treatment with another investigational drug or licensed live vaccine within 30 days prior to or after planned enrollment. Subjects will be informed of local availability and be eligible to obtain an authorized COVID-19 vaccine at the time of enrollment and at any time during the study
11. Known history of COVID-19 infection
12. Receipt of any antibody (e.g. TIG, VZIG, IVIG, IM gamma globulin, monoclonal antibody) or blood or plasma transfusion within 6 months or within 5 half-lives of the specific antibody product given
13. History of solid organ or bone marrow transplantation
14. Active drug or alcohol use disorder or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements
15. Use of H1 antihistamines or beta-blockers within 5 days of dosing (PRN use of H1 antihistamines may be acceptable after Medical Monitor approval)

17. Plans to enroll or is already enrolled in another interventional study
18. Has contraindication to IM injections or blood draws e.g., bleeding disorders, use of any anti-coagulants
