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
