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

Must be sero-susceptible ≤10 hemagglutination inhibition (HAI) titre to CA/07/2009 Influenza virus (pre-screen).
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)
