Eligibility
Key inclusion criteria
1. Adult volunteers, aged 18 to 45 years (at the time of screening) in good general health in the opinion of the Medical Investigator or delegate, with no significant medical history and no clinically significant abnormal findings at screening.
2. Participants must use highly effective, double contraception from the Screening Visit and up to the Follow-up Visit (Day 30).

2. Blood, tissue or organs must not be donated within 7 days of vaccination
3. Severely immunosuppressed persons who require a protective environment are not to be cared for by the participant within 7 days of vaccination
4. Contact is not to be made with severely immunosuppressed persons who require a protective environment within 7 days of vaccination
5. All tissues and materials used to collect respiratory secretions are to be sealed in a primary container and placed within a secondary container so that it is not accessible to children or animals for 7 days until it is returned to the study site for disposal, for 7 days within vaccination

6. Must be sero-susceptible =10 hemagglutination inhibition (HAI) titre to CA/07/2009 Influenza virus (pre-screen).
7. Laboratory Testing:

1. Full blood examination and biochemistry within the laboratory defined normal range unless deemed not clinically significant by the investigator, however a small drop below the normal range for Absolute Neutrophil Count (ANC) may be acceptable as per investigator discretion;
2. Urinalysis: Negative urine glucose, negative or trace urine protein, negative or trace urine hemoglobin (if trace hemoglobin is present on dipstick, a microscopic urinalysis within institutional range)
