• Available for the duration of the trial.
• Good general health as shown by medical history, physical exam, and screening laboratory tests.
• The following laboratory parameters:
• Hematology
• Hemoglobin ≥10.5 g/dL for women; ≥11 g/dL for men
• Absolute Neutrophil Count (ANC): ≥1000/mm3
• Platelets: 125,000 to 550,000/mm3
• Chemistry
• Creatinine: <1.1 x upper limit of normal (ULN)
• AST: <1.25 x ULN
• ALT: <1.25 x ULN
• Normal 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).
• All female participants must be willing to undergo serum or urine beta human chorionic gonadotropin pregnancy tests at time points indicated in the Schedule of Procedures and must test negative prior to vaccination.
• All sexually active males (unless anatomically sterile) must be willing to use an effective method of contraception (such as consistent condom use) from the day of first vaccination until Week 12.
• If a woman of child-bearing potential, committed to use an effective method of contraception when sexually active with men until Week 12, including:

• Intrauterine device.
• Hormonal contraception.

You may not qualify if…

• History of known flavivirus infection or previous receipt of flavivirus vaccine.
• Positive serology for HIV-1, Hepatitis B surface antigen, or anti-hepatitis C virus antibodies prior to enrollment.
• Planned travel to areas with active Zika virus transmission during the study period.
• Recent (within 3 weeks) travel to an area with active Zika virus transmission.
• Current or planned participation in another clinical trial of an experimental agent during the study period.
• Pregnant or lactating.
• Any condition, including any clinically significant acute or chronic medical condition, for which, in the opinion of the investigator, participation would not be in the best interest of the subject (eg, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments.
• Use of anticancer, antituberculosis or other medications considered significant by the investigator within the previous 6 months.
• Receipt of live-attenuated vaccine within the previous 60 days or planned receipt within 60 days after vaccination with Investigational Product (within 14 days for live attenuated influenza vaccine [LAIV]); or receipt of other vaccine (e.g., influenza, pneumococcal), allergy treatment with antigen injections or tuberculin skin test within the previous 14 days or planned receipt within 14 days after vaccination with Investigational Product
• Receipt of blood transfusion or blood-derived products within the previous 3 months.
• Previous severe local or systemic reactions to vaccination.
• History of splenectomy
• History of seizure in the last 3 years (participants with a history of seizures who have neither required medications nor had a seizure for 3 years are not excluded)
• Known autoimmune disease
• Asthma other than mild, well-controlled asthma. Exclude participants who:
• Use a bronchodilator (beta 2 agonist) daily, or
• In the past year have (any of the following):
• i. Had > 1 exacerbation of symptoms treated with oral steroids ii. Routinely used moderate to high dose inhaled corticosteroids (e.g., more than the equivalent of 250 mcg fluticasone; 400 mcg budesonide; 500 mcg beclomethasone; or 1000 mcg triamcinolone/flunisolide, as a daily dose) or theophylline iii. Needed emergency care, urgent care, hospitalization, or intubation for asthma c. Prophylactic bronchodilator use prior to exercise is not exclusionary

• Angioedema within the last 3 years if episodes are considered serious or have required medication within the last 2 years
• Uncontrolled Hypertension:
• If a person has been diagnosed with hypertension during screening or previously, exclude for hypertension that is not well controlled. Well- controlled hypertension is defined as blood pressure consistently ≤ 140 mm Hg systolic and ≤ 90 mm Hg diastolic, with or without medication, with only isolated, brief instances of higher readings, which must be ≤ 150 mm
• If a person has NOT been diagnosed with hypertension during screening or previously, exclude for systolic blood pressure ≥ 150 mm Hg at enrollment or diastolic blood pressure ≥ 90 mm Hg at enrolment
• Bleeding disorder diagnosed by a doctor (e.g. factor deficiency, coagulopathy, or platelet disorder requiring special precautions)
