- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE1
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~1. Must be a male or non-pregnant, non-breastfeeding female between the ages of 18 and 49 years, inclusive, at the time of screening and enrollment.~2. Must be willing and able to read, sign, and date the informed consent document before study-related procedures are performed.~3. Must be willing and able to comply with study requirements and be available for follow-up visits for the entire study.~4. Must have a means to be contacted by telephone.~5. Must have a body mass index (BMI) \>/=18.1 and \<35.0 kg/m2.~6. Must have acceptable screening laboratory findings within 40 days before day 1.~   * Acceptable clinical laboratory parameters include no more than Grade 1 on toxicity scale.~  * White Blood Cell (WBC), Hemoglobin, and platelet count will be reported as part of the Complete Blood Count (CBC). These labs will be graded according to the toxicity scale. Other results included on the CBC panel will not be graded. They will be reviewed by an investigator who will determine clinical significance and may be used to determine additional workup.~  * Sodium, potassium, blood urea nitrogen (BUN), creatinine, random glucose, total protein, albumin, calcium, AST, ALT, total bilirubin, and alkaline phosphatase will be reported as part of the Complete Metabolic Panel (CMP). These labs will be graded according to the toxicity scale. Other results included on the CMP panel will not be graded. They will be reviewed by an investigator who will determine clinical significance and may be used to determine additional workup.~   Note: If laboratory screening tests are out of acceptable range, repeat of screening tests is permitted one time, provided there is an alternative explanation for the out of range value.~7. Must be in good health based on the investigator's clinical judgment when considering findings from past medical history, medication use, vital signs, and an abbreviated physical examination.~   Note 1: Good health is defined by the absence of any medical condition described in the exclusion criteria in a subject with a normal abbreviated physical exam and vital signs. If the subject has a preexisting condition not listed in the exclusion criteria, the condition cannot meet any of the following criteria: first diagnosed in the last 3 months; worsening in terms of clinical outcome in the last 6 months; or involves need for medication that may pose a risk to the subject's safety or impede assessment of AEs or immunogenicity if they participate in the study.~   Note 2: An abbreviated physical exam differs from a complete exam in that it does not include a genitourinary and rectal exam.~   Note 3: Vital signs must be normal by protocol toxicity grading scale or determined to be normal-variant by investigator. In the event of an abnormal heart rate or blood pressure due to physiological variation or activity, the subject may rest for 10 minutes in a quiet room, and then blood pressure and/or heart rate may be re-measured. Repeated vital signs may be used to determine eligibility.~8. Women of childbearing potential must have a negative urine pregnancy test at screening and a negative urine pregnancy test immediately prior to each vaccination.~   Note: All female subjects are considered of childbearing potential unless postmenopausal or surgically sterile and \>/=3 months have passed since sterilization procedure. Postmenopausal is defined as amenorrhea for \>/=12 months without an alternative medical cause. Permanent female sterilization procedures include tubal ligation, bilateral salpingectomy, hysterectomy, bilateral oophorectomy, or successful Essure placement.~9. Women of childbearing potential must use an acceptable method of contraception from one month (30 days) prior to the first vaccination until at least 60 days after the last vaccination.~   * Acceptable methods of contraception include the following: Use highly effective contraceptive methods, defined by \<1% failure rate per year independent of user adherence, including long-acting reversible contraception (LARC): progestin-releasing subdermal implants and intrauterine devices (IUD). Use effective contraceptive methods, defined by 5-9% failure rate with typical use and \<1% failure rate with consistent and correct use, including: prescription oral contraceptives, contraceptive injections, combined pill, progestin-only pill, hormone-releasing transdermal patch or vaginal ring, and depot medroxyprogesterone acetate injection (Depo-Provera). Have one male sex partner who has had a vasectomy \>/=3 months prior. Male partner with barrier protection plus the use of vaginal spermicide. Practice abstinence defined as refraining from heterosexual intercourse from 30 days before first vaccination until at least 60 days after last ZPIV vaccination.~10.

In the event of an abnormal heart rate or blood pressure due to physiological variation or activity, the subject may rest for 10 minutes in a quiet room, and then blood pressure and/or heart rate may be re-measured. Repeated vital signs may be used to determine eligibility.~15. Has current or past history of substance abuse that in the investigator's opinion would preclude participation.~16.
