Summary
This is a single center, randomized, partially-blinded, Phase II, small, targeted, prospective study in approximately 30 healthy male and non-pregnant female subjects aged 18 to 49 years old, inclusive, designed to evaluate and compare the immunogenicity between an intramuscular monovalent inactivated influenza A/H7N9 virus vaccine given with and without AS03 adjuvant, and an intramuscular unadjuvanted monovalent inactivated influenza A/H3N2v virus vaccine. The primary objectives are (1) assessing the serum anti-HA hemagglutination-inhibition (HAI) response to influenza A/H7N9 antigen (with and without adjuvant) at Day 57 (approximately one month after the second study vaccination with A/H7N9 vaccine with or without AS03) and influenza A/H3N2v antigen at Day 29 (approximately one month after the study vaccination with A/H3N2v), and (2) identifying differentially expressed genes in human immune cells on Days 2, 4, and 29 (following the first study vaccination with A/H7N9 vaccine with or without AS03) and on Days 30, 32, and 36 (following the second study vaccination with A/H7N9 vaccine with or without AS03), compared to baseline assessments performed prior to each study vaccination (Days -7, 1, and 29).

Criteria
Inclusion Criteria:

1. Provide written informed consent prior to initiation of any study procedures.

2. Are able to understand and comply with planned study procedures and be available for
all study visits.

3. Are males or non-pregnant females, 18 to 49 years old, inclusive.

4. Are in good health*.

*As determined by medical history and targeted physical examination, if indicated
based on medical history, to evaluate acute or currently ongoing chronic medical
diagnoses or conditions, defined as those that have been present for at least 90 days,
that would affect the assessment of the safety of subjects or the immunogenicity of
study vaccinations. Chronic medical diagnoses or conditions should be stable for the
last 60 days. This includes no change in chronic prescription medication, dose, or
frequency as a result of deterioration of the chronic medical diagnosis or condition
in the 60 days prior to enrollment. Any prescription change that is due to change of
health care provider, insurance company, etc., or that is done for financial reasons,
as long as in the same class of medication, will not be considered a deviation of this
inclusion criterion. Any change in prescription medication due to improvement of a
disease outcome, as determined by the site principal investigator or appropriate
sub-investigator, will not be considered a deviation of this inclusion criterion.
Subjects may be on chronic or as needed (prn) medications if, in the opinion of the
site principal investigator or appropriate sub-investigator, they pose no additional
risk to subject safety or assessment of reactogenicity and immunogenicity and do not
indicate a worsening of medical diagnosis or condition. Similarly, medication changes
subsequent to enrollment and study vaccination are acceptable provided there was no
deterioration in the subject's chronic medical condition that necessitated a
medication change, and there is no additional risk to the subject or interference with
the evaluation of responses to study vaccination. Note: Topical, nasal, and inhaled
medications (with the exception of inhaled corticosteroids as outlined in the Subject
Exclusion Criteria), herbals, vitamins, and supplements are permitted.

5. Oral temperature is less than 100.4 degrees F.

6. Pulse is 50 to 115 bpm, inclusive.

7. Systolic blood pressure is 85 to 150 mm Hg, inclusive.

8. Diastolic blood pressure is 55 to 95 mm Hg, inclusive.

9. Erythrocyte sedimentation rate (ESR) is less than 30 mm per hour.

10. Women of childbearing potential* must use an acceptable contraception method** from 30
days before first study vaccination until 60 days after last study vaccination.

*Not sterilized via tubal ligation, bilateral oophorectomy, hysterectomy or successful
Essure (R) placement (permanent, non-surgical, non-hormonal sterilization) with
documented radiological confirmation test at least 90 days after the procedure, and
still menstruating or <1 year of the last menses if menopausal.

**Includes, but is not limited to, non-male sexual relationships abstinence from
sexual intercourse with a male partner, monogamous relationship with vasectomized
partner who has been vasectomized for 180 days or more prior to the subject receiving
the first study vaccination, barrier methods such as condoms or diaphragms with
spermicide or foam, effective intrauterine devices, NuvaRing (R), and licensed
hormonal methods such as implants, injectables or oral contraceptives ("the pill").

11. Women of childbearing potential must have a negative urine or serum pregnancy test
within 24 hours prior to study vaccination.

Exclusion Criteria:

1. Have an acute illness*, as determined by the site principal investigator or
appropriate sub-investigator, within 72 hours prior to study vaccination.

*An acute illness which is nearly resolved with only minor residual symptoms remaining
is allowable if, in the opinion of the site principal investigator or appropriate
sub-investigator, the residual symptoms will not interfere with the ability to assess
safety parameters as required by the protocol.

2. Have any medical disease or condition that, in the opinion of the site principal
investigator or appropriate sub-investigator, is a contraindication to study
participation*.

*Including acute or chronic medical disease or condition, defined as persisting for at
least 90 days that would place the subject at an unacceptable risk of injury, render
the subject unable to meet the requirements of the protocol, or may interfere with the
evaluation of responses or the subject's successful completion of this study.

3. Have immunosuppression as a result of an underlying illness or treatment, or use of
anticancer chemotherapy or radiation therapy (cytotoxic) within 3 years prior to study
vaccination.

4. Have known active neoplastic disease (excluding non-melanoma skin cancer) or a history
of any hematologic malignancy.

5. Have known human immunodeficiency virus (HIV), hepatitis B, or hepatitis C infection.
