| Eligibility |
Inclusion Criteria:
1. Healthy male or non-pregnant female, =18 and =50 years of age, with BMI =18 and = 34.0
kg/m2 and body weight =50.0 kg for males and =45.0 kg for females.
2. Healthy as defined by:
1. The absence of clinically significant illness and surgery within 28 days prior to
dosing. Subjects displaying signs or symptoms of an acute and/or febrile illness
within 24 hours pre-dose (at least 3 symptom-free pre-dose days required) will be
carefully evaluated for upcoming illness/disease. Inclusion of pre-dosing is at
the discretion of the Investigator, and the subject may have their scheduled
dosing postponed until the condition resolves.
2. The absence of clinically significant history of neurological, endocrine,
cardiovascular, respiratory, haematological, immunological, psychiatric,
gastrointestinal, renal, hepatic, and metabolic disease.
3. Non-smokers or social smokers (defined as the equivalent or fewer than 10 cigarettes
per week). Ex-heavy smokers (heavy smoking is defined as the equivalent of 25 or more
cigarettes per day) may be admitted if they have quit or reduced their cigarette
intake to the defined level of social smoking, for a period of at least 12 months.
Ex-moderate level smokers (i.e. >10 per week but <25 per day) may be admitted if they
have quit or reduced their cigarette intake to the defined level of social smoking,
for a period of at least 6 months.
4. All women of child bearing potential (WOCBP) and men must refrain from sperm/egg
donation and must be able and willing to use at least 1 highly effective method of
contraception commencing at least 28 days prior to vaccine administration and for 3
months after vaccine administration. Subjects in same sex relationships must be able
and willing to refrain from sperm/egg donation for 3 months after vaccine
administration. A female subject is considered to be a WOCBP following menarche and
until she is in a post-menopausal state for 12 consecutive months (without an
alternative medical cause) or otherwise permanently sterile (for which acceptable
methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy). A
follicle-stimulating hormone (FSH) test may be used to confirm a post-menopausal
state. Examples of acceptable methods of contraceptive methods (for female subjects
and female partners of male subjects) to be used throughout the study include
1. Use of hormonal contraceptives, started at at least 28 days prior to study
treatment administration and must agree to use the same hormonal contraceptive
throughout the study;
2. Use of an intra-uterine contraceptive device, placed at at least 28 days prior to
study treatment administration;
3. Use of a diaphragm, started at least 28 days prior to study treatment
administration;
4. Use of condoms for male subjects whose partners are pregnant to ensure that the
foetus is not exposed to the study vaccine;
5. Sterile male partner (vasectomized since at least 6 months prior to study
treatment administration)
6. True abstinence, defined as no sexual intercourse with a male partner, (for
heterosexual couples) from the time of enrollment and at for at least 28 days
prior to study treatment administration and for at least the duration of the
study. Periodic abstinence and withdrawal are not acceptable methods.
5. Must meet the following COVID-19 vaccination status:
1. Have completed a primary SARS-CoV-2 vaccination series with either the Pfizer or
Moderna COVID-19 vaccine, and
2. Have received at least one booster dose of the Pfizer or Moderna SARS-CoV-2
vaccine at least 3 months prior to study entry.
6. WOCBP must return a negative urine pregnancy test prior to receiving the study
treatment.
7. Male subjects (including men who have had a vasectomy) with a pregnant partner, a
female partner not of childbearing potential, or a same sex partner, must agree to use
a condom from study treatment administration until at least 90 days after the last
study treatment administration.
8. Must be willing to refrain from blood (and plasma) donation throughout study
participation.
9. Must be able to attend all visits for the duration of the study and comply with all
study procedures according to the study schedule.
Exclusion Criteria:
Subjects to whom any of the following applies will be excluded from the study:
1. Any clinically significant abnormality or vital sign abnormality at physical
examination (including baseline resting average high blood pressure [average systolic
blood pressure =140 mmHg or resting average diastolic blood pressure =90 mmHg or high
random blood sugar [nonfasting]), clinically significant abnormal laboratory test
results or positive test for HIV, hepatitis B, or hepatitis C found during medical
screening.
2. Any acute or chronic ongoing illness which, in the judgement of the investigator, may
preclude the subject's participation. Subjects who have a chronic condition that is
stable and controlled and otherwise healthy should not be excluded. Within at least
the past 3 months must NOT have received another COVID-19 vaccine.
3. Persons who received another COVID-19 vaccine within the past 3 months prior to
dosing.
4. Persons who received a primary vaccination series and or a booster vaccination dose of
a non-mRNA COVID-19 vaccine (ie Matrix M adjuvanted COVID-19 vaccine, Novavax).
5. Persons who have a history of COVID-19 or virologically confirmed SARS-CoV-2 infection
in the past 3 months.
6. Persons with a history of COVID-19 with ongoing sequelae.
7. Persons with a history of myocarditis and/or pericarditis.
8. Positive pregnancy, urine drug screen, or alcohol breath test at screening.
9. Known history of allergic reactions or hypersensitivity to any vaccine, or to any
excipient in the formulation (including the adjuvants: MF59C.1 and Matrix-M).
10. Presence of a known, or suspected, impairment of the immune system including, but not
limited to, HIV, autoimmune disorders, immunosuppressant therapy, and diabetes
mellitus.
11. History of a known, or suspected, respiratory system disorder including, but not
limited to, cystic fibrosis, reactive airway disease, emphysema, chronic bronchitis,
chronic obstructive pulmonary disease (COPD), or asthma, excluding childhood asthma.
12. History of significant alcohol abuse within 12 months prior to screening.
13. Positive test for drugs of abuse (such as marijuana/ tetrahydrocannabinol [THC]
products, amphetamine, methamphetamine, methadone, barbiturates, benzodiazepines,

screening.
14. Participation in a clinical research study involving the administration of an
investigational, or marketed, drug or device within 30 days prior to receiving the
treatment administration, or administration of a biological product in the context of
a clinical research study within 90 days prior to dosing, or concomitant participation
in an investigational study involving drug, vaccine, or device administration, or
intent to participate in another clinical study at any time during the conduct of the
study.
15. Use of medications for the timeframes specified below, (except for hormonal
contraceptives and medications exempted by the Investigator on a case-by-case basis)

without significant systemic absorption are permissible:
1. A new, or a change in a prescription medication within 14 days prior to treatment
administration;

5. Over-the-counter products within 7 days prior to dosing, with the exception of
the occasional use of paracetamol (up to 2 g daily) and standard dose vitamins.
16. Donation of plasma within 7 days prior to dosing. Donation or loss of blood (excluding
volume drawn at screening) of 50 mL to 499 mL of blood within 30 days, or more than

affiliates or partners, or Syneos Health.
21. Employees of the specific team at the University of Queensland responsible for
manufacturing and managing the IP (Investigational Product) or their immediate

22. Any reason that, in the opinion of the Investigator, would interfere with the primary
