VELOCITY: An Anthrax Vaccine Clinical Study

Inclusion Criteria: 1. Written informed consent obtained from the participant (dated and signed). 2. Healthy condition as established by medical history and clinical examination before entering into the study. 3. A male or female aged 18 to 65 years, inclusive, at the time of informed consent. 4. Body mass index (BMI) ≤35.0 kg/m\^2 at Screening visit. 5. Have adequate venous access for phlebotomies. 6. For a woman of childbearing potential (WOCBP), negative serum pregnancy test at Screening and negative urine pregnancy test prevaccination on Day 1, not currently breastfeeding, and no intention to become pregnant during the study through Month 13. Every female participant is considered to be a WOCBP unless surgically sterile (bilateral oophorectomy or bilateral salpingectomy or hysterectomy) OR postmenopausal (defined as \>12 consecutive months without menses and screening follicle-stimulating hormone \>30 mIU/mL). Women who are not of childbearing potential are allowed to enroll if they are surgically sterile or postmenopausal as defined above. Exclusion Criteria: 1.

Positive test result on urine drug screen, any evidence of ongoing drug abuse or dependence (including alcohol), or recent history (over the past five years) of treatment for alcohol or drug abuse. 3. Chronic administration (defined as \>14 days) of immunosuppressants or other immune-modifying drugs (includes oral or parenteral corticosteroids, for example, a glucocorticoid dose exceeding 10 mg/day prednisone or equivalent) within six months prior to the vaccine dose; inhalation use (for example, for seasonal allergies) is permitted. 4. Planned administration of any commercially-available vaccine from seven days prior to the first study vaccination through two weeks after the last vaccination. 5. Previous anaphylactic reaction, severe systemic response, or serious hypersensitivity to a prior immunization or a known allergy to synthetic Oligodeoxynucleotides, aluminum, formaldehyde, benzethonium chloride (phemerol), or latex. 6. History of anthrax disease, suspected exposure to anthrax, or previous vaccination with any anthrax vaccine. 7. Have a tattoo/scar/birthmark or any other skin condition affecting the deltoid area that may interfere with injection site assessments. 8.

Acute disease at the time of enrollment. Note that screening lab tests may be delayed to allow the resolution of a transient acute condition or the subject may be rescreened. 13. Any medical condition that, in the opinion of the investigator, could adversely impact the participant's participation or the conduct of the study. 14. Any planned elective surgery during the study through 12 months after the last vaccination. 15. Planned receipt of immunoglobulins and/or any blood products within the three months preceding study enrollment or at any point during the study period until after the final safety phone contact. 16. Woman of childbearing potential refusing to practice an adequate method of contraception from at least one month before Day 1 and continuing through Month 13. An adequate method of contraception is defined as abstinence from sexual intercourse; prior bilateral tubal ligation; monogamous relationship with a vasectomized partner (vasectomy performed at least six months prior to the participant's screening visit); or any of these forms of birth control: pill, intrauterine device (IUD), implantable or injectable contraceptive (for example, Norplant® or Depo-Provera®), removable device (for example, NuvaRing® or Evra® patch), or double-barrier method (condom with spermicide, diaphragm with spermicide).
