Description
Inclusion Criteria:
-Provide written informed consent prior to initiation of any study procedures. -Are able to understand and comply with planned study procedures and be available for all study visits. -Are males or non-pregnant females, 19 to 64 years old, inclusive. -Are in good health, as determined by vital signs (oral temperature, pulse, and blood pressure), medical history, and targeted physical examination based on medical history to ensure any existing medical diagnoses or conditions (except those in the Subject Exclusion Criteria) are stable. 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. Note: Topical, nasal, and inhaled medications (with the exception of steroids as outlined in the Subject Exclusion Criteria (see section 5.2)), vitamins, and contraceptives are permitted. -Oral temperature is less than 100.4 degrees F. -Pulse is 50 to 115 bpm, inclusive. -Systolic blood pressure is 85 to 150 mmHg, inclusive. -Diastolic blood pressure is 55 to 95 mmHg, inclusive. -Female subjects of childbearing potential who are not surgically sterile via tubal sterilization, bilateral oophorectomy, or hysterectomy or who are not postmenopausal for >/= 1 year must agree to practice highly effective contraception that may include, but is not limited to, abstinence from intercourse with a male partner, monogamous relationship with a vasectomized partner, male condoms with the use of applied spermicide, intrauterine devices, and licensed hormonal methods with use of a highly effective method of contraception for a minimum of 30 days prior to study product exposure and agree to practice highly effective contraception for the duration of study product exposure, including 2 months (defined as 60 days)after the last study vaccination. A highly effective method of contraception is defined as one which results in a low failure rate (i.e., less than 1 percent per year) when used consistently and correctly. Method of contraception will be captured on the appropriate data collection form. -Female subjects of childbearing potential must have a negative urine or serum pregnancy test within 24 hours prior to study vaccination.
Exclusion Criteria:
-Have an acute illness within 72 hours prior to study vaccination. -Have any condition that, in the opinion of the site principal investigator or appropriate sub-investigator, would place the subject at an unacceptable risk of injury, render the subject unable to meet the requirements of the protocol, or confound the interpretation of the results. -Have an acute or chronic medical condition that, in the opinion of the site principal investigator or appropriate sub-investigator, would render vaccination unsafe, or would interfere with the evaluation of responses. -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. -Have known active neoplastic disease or a history of any hematologic malignancy. -Have known HIV, hepatitis B, or hepatitis C infection. -Have known hypersensitivity or allergy to eggs, egg or chicken protein, squalene-based adjuvants, or other components of the study vaccine. -Have a history of severe reactions following previous immunization with licensed or unlicensed influenza virus vaccines. -Have a history of Guillain-Barré Syndrome. - Have a history of neuralgia, paresthesia, neuritis, convulsions, or encephalomyelitis within 90 days prior to study vaccination. -Have a history of autoimmune disease, including but not limited to neuroinflammatory diseases, vasculitis, clotting disorders, dermatitis, arthritis, thyroiditis, or muscle, liver or kidney disease. -Have a history of alcohol or drug abuse within 5 years prior to study vaccination. -Have any diagnosis, current or past, of schizophrenia, bipolar disease, or other psychiatric diagnosis that may interfere with subject compliance or safety evaluations. -Have been hospitalized for psychiatric illness, history of suicide attempt, or confinement for danger to self or others within 10 years prior to study vaccination. -Have taken oral or parenteral corticosteroids of any dose within 30 days prior to study vaccination. -Have taken high-dose inhaled corticosteroids within 30 days prior to study vaccination. High-dose defined as >800mcg/day of beclomethasone dipropionate CFC or equivalent. -Received any licensed live vaccine within 30 days or any licensed inactivated vaccine within 14 days prior to the first study vaccination or planned receipt of any vaccine from the first study vaccination through the follow-up visit at approximately 21 days after the last study vaccination. This is inclusive of licensed seasonal influenza vaccines. -Received immunoglobulin or other blood products (with exception of Rho D immunoglobulin) within 90 days prior to study vaccination. -Received an experimental agent (vaccine, drug, biologic, device, blood product, or medication) within 30 days prior to the first study vaccination, or expects to receive an experimental agent other than from participation in this study during the 13-month study period. -Are participating or plan to participate in another clinical trial with an interventional agent (licensed or unlicensed vaccine, drug, biologic, device, blood product, or medication) during the 13-month study period. -Prior participation in a clinical trial of influenza A/H7 vaccine and assigned to a group receiving influenza A/H7 vaccine (does not apply to documented placebo recipients) or have a history of A/H7 actual or potential exposure or infection prior to the first study vaccination. -Plan to travel outside the U.S. (continental U.S., Hawaii and Alaska) in the time between the first study vaccination and 42 days after the first study vaccination. -Female subjects who are breastfe eding or plan to breastfeed at any given time from the first study vaccination until 30 days after their last study vaccination. -Blood donation within 30 days prior to enrollment and within 30 days after the last blood draw (only for a subset of healthy adult subjects - up to 75 volunteers, 19-64 years old, enrolled at the Emory VTEU site, who consent to blood donation for the immunology exploratory assays).
