  • Currently participating in another study with an investigational product during the conduct of this study;
  • Previous or planned receipt of any COVID-19 booster vaccine during the trial period
  • Medical conditions as follows:

    • Respiratory diseases
    • History of hypersensitivity or severe allergic reaction
    • Uncontrolled hypertension
    • Uncontrolled diabetes mellitus
    • Malignancy within the past 2 years, with the exception of superficial skin
    • History of cardiovascular disease
    • History of myocarditis or pericarditis
    • History of seizures within the past 2 years
    • Underlying immunosuppressive illness
  • Lack of acceptable sites for ID injection and EP
  • Blood donation or transfusion within 1 month prior to Day 0;
  • Reported alcohol or substance abuse/dependence or illicit drug use within the past year;
