Summary:

      This is a randomized, un-blinded, Phase II study in males and non-pregnant females, who are
      in good health, 19 to 64 years of age. This study is designed to assess the safety,
      reactogenicity, and immunogenicity of a pre-pandemic AS03 (GSK) adjuvanted 2017 monovalent
      inactivated influenza A/H7N9 vaccine, when two doses are administered 21 days apart either
      sequentially or simultaneously (within 15 minutes) with licensed seasonal influenza vaccine.
      Subjects will be randomized into one of three treatment groups. The study will enroll
      approximately 150 individuals who have no history of influenza A/H7N9 infection or prior
      receipt of an influenza virus H7 subtype vaccine. Study duration is approximately 16 months
      with subject participation duration of approximately 13 months. The primary objectives of
      this study are: 1) to assess the safety and reactogenicity following sequential or
      simultaneous IM administration of 2 doses of AS03-adjuvanted 2017 H7N9 IIV and one dose of
      seasonal influenza vaccine (IIV4); 2) to assess the serum HAI and Neut antibody responses
      against A/H7N9 at approximately 21 days following receipt of two doses of AS03-adjuvanted
      2017 H7N9 IIV administered IM approximately 21 days apart; 3) to assess the serum HAI and
      Neut antibody responses against the seasonal influenza strains at approximately 21 days
      following receipt of IIV4.
    

Eligibility 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, 19 -64 years of age, inclusive.

          4. Are in good health. - As determined by medical history and physical examination to
             evaluate acute or currently ongoing chronic medical diagnoses or conditions, defined
             as those that have been present for at least 90 days, which 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 (no
             hospitalizations, Emergency Room (ER), or urgent care for condition and no adverse
             symptoms that need medical intervention such as medication change/supplemental
             oxygen). 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 100.0°F.

          7. Systolic blood pressure is 85 to 150 mmHg, inclusive (subjects <65 years of age), 85
             to 160 mmHg, inclusive (subjects = / > 65 years of age).

          8. Diastolic blood pressure is 55 to 95 mmHg, inclusive.

          9. 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.

             hysterectomy, or successful Essure® 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 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

             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

             - 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 trial.

          3. Have immunosuppression as a result of an underlying illness or treatment, a recent
