Eligibility Criteria

Inclusion Criteria

  • 1 Adult, ≥ 18 years of age at the time of consent
  • Type of Participant
  • 2 Increased risk of SARS-CoV-2 infection
  •  Defined as adults whose locations or circumstances put them at appreciable risk of
  • exposure to SARS-CoV-2 and COVID-19, based on available risk assessment
  • contemporaneous to enrollment (believed to be at risk/exposure)
  • 3 Medically stable such that, according to the judgment of the investigator, hospitalization
  • within the study period is not anticipated and the participant appears likely to be able to
  • remain on study through the end of protocol-specified follow-upA stable medical
  • condition is defined as disease not requiring significant change in therapy or
  • hospitalization for worsening disease during the 3 months prior to enrollmentAble to
  • understand and comply with study requirements/procedures (if applicable, with assistance
  • by caregiver, surrogate, or legally authorized representative) based on the assessment of
  • the investigator
  • Reproduction
  • 5 Contraceptive use by women should be consistent with local regulations regarding the
  • methods of contraception for those participating in clinical studies
  • 6 Female participants
  • (a) Women of childbearing potential must:
  •  Have a negative pregnancy test on the day of screening and on Day 1
  •  Use one highly effective form of birth control for at least 28 days prior to Day 1
  • and agree to continue using one highly effective form of birth control through
  • 60 days following administration of the second dose of study intervention. A
  • highly effective method of contraception is defined as one that can achieve a
  • failure rate of less than 1% per year when used consistently and correctly (see
  • Table 6). Periodic abstinence, the rhythm method, and withdrawal are NOT
  • acceptable methods of contraception.
  • (b) Women are considered of childbearing potential unless they meet either of the
  • following criteria:
  •  Surgically sterilized (including bilateral tubal ligation, bilateral oophorectomy, or
  • hysterectomy), or
  •  Post-menopausal
  •  For women aged < 50 years, post-menopausal is defined as having both:
  • o A history of ≥ 12 months amenorrhea prior to randomization, without
  • an alternative cause, following cessation of exogenous sex-hormonal
  • treatment, and
  • A follicle-stimulating hormone level in the post-menopausal range
  • Until follicle-stimulating hormone is documented to be within menopausal
  • range, the participant is to be considered of childbearing potential
  •  For women aged ≥ 50 years, post-menopausal is defined as having a history
  • of ≥ 12 months amenorrhea prior to randomization, without an alternative
  • cause, following cessation of exogenous sex-hormonal treatment
  • Informed Consent
  • 7 Capable of giving signed informed consent as described in Appendix A, which includes
  • compliance with the requirements and restrictions listed in the ICF and in this protocol

Exclusion Criteria

  • Participants are excluded from the study if any of the following criteria apply:
  • Medical Conditions
  • 1 History of allergy to any component of the vaccine
  • 2 History of Guillain-Barre syndrome
  • 3 Significant infection or other acute illness, including fever > 100 ℉ (> 37.8 °C) on the
  • day prior to or day of randomization
  • 4 History of laboratory-confirmed SARS-CoV-2 infection
  • 5 Any confirmed or suspected immunosuppressive or immunodeficient state, including
  • 6 Recurrent severe infections and use of immunosuppressant medication within the past
  • 6 months (≥ 20 mg/kg/day of prednisone or its equivalent, given daily or on alternate days
  • for ≥ 15 days within 30 days prior to administration of study intervention)
  • The following exceptions are permitted:
  •  Topical/inhaled steroids or short-term oral steroids (course lasting ≤ 14 days)
  •  Human immunodeficiency virus-positive stable participants on stable antiretroviral
  • therapy (Waldrop et al, 2016)
  • 7 History of primary malignancy except for:
  • (a) Malignancy with low potential risk for recurrence after curative treatment (for
  • example, history of childhood leukaemia) or metastasis (for example, indolent
  • prostate cancer) in the opinion of the site investigator.
  • (b) Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of
  • (c) Adequately treated uterine cervical carcinoma in situ without evidence of disease
  • (d) Localized prostate cancer
  • 8 Clinically significant bleeding disorder (eg, factor deficiency, coagulopathy, or platelet
  • disorder), or prior history of significant bleeding or bruising following IM injections or
  • venepuncture
  • 9 Severe and/or uncontrolled cardiovascular disease, respiratory disease, gastrointestinal
  • disease, liver disease, renal disease, endocrine disorder, and neurological illness, as
  • judged by the Investigator (mild/moderate well-controlled comorbidities are allowed)
  • 10 Any other significant disease, disorder, or finding that may significantly increase the risk
  • to the participant because of participation in the study, affect the ability of the participant
  • to participate in the study, or impair interpretation of the study data
  • Prior/Concomitant Therapy
  • 11 Receipt of, or planned receipt of investigational products indicated for the treatment or
  • prevention of SARS-CoV-2 or COVID-19
  • Note: For participants who become hospitalized with COVID-19, receipt of licensed
  • treatment options and/or participation in investigational treatment studies is permitted
  • 12 Receipt of any vaccine (licensed or investigational) other than licensed influenza vaccines
  • within 30 days prior to and after administration of study intervention
  • 13 Receipt of immunoglobulins and/or any blood products within 3 months prior to
  • administration of study intervention or expected receipt during the period of study
  • Other Exclusions
  • 14 Involvement in the planning and/or conduct of this study (applies to both Sponsor staff
  • and/or staff at the study site)
  • 15 For women only - currently pregnant (confirmed with positive pregnancy test) or
  • breast-feeding
  • 16 Has donated ≥ 450 mL of blood products within 30 days prior to randomization or
  • expects to donate blood within 90 days of administration of s
