  • Willingness to complete the Volunteer Diary and to report concomitant medications and adverse events (AEs) to the study site monitors during the study period.

Exclusion Criteria:

  • Prior history of, or known exposure to any form of B. anthracis or any anthrax immunization.
  • Member of the Armed Services (Active Duty or Reserve) since 1990, with history of previous anthrax vaccination.
  • Employment in an industry involved in contact with ruminant animals, veterinary sciences, or other exposure to B. anthracis.
  • Expected to be noncompliant with study visits or planning to move within 8 months.
  • Body mass index of >35 or <19.
  • Known allergy to aluminum hydroxide, formaldehyde, benzethonium chloride, latex, kanamycin, or any other aminoglycoside antibiotics (such as gentamycin).
  • Pregnancy (positive urine pregnancy test within 24 hours prior to vaccination), or lactation.
  • HIV positive (by history or screening ELISA).
  • Hepatitis B or C positive (by history or screening HBsAg/anti-HCV ELISA).
  • Active or past internal organ, hematologic malignancy, or metastatic cutaneous malignancy.
  • History of, or current autoimmune disease, including but not limited to systemic lupus erythematosus, scleroderma, and polyarteritis.
  • Immunodeficiency or unstable medical condition as determined by baseline medical history, physical exam, and laboratory assessment.
  • Received, or plans to receive, licensed live vaccines within 30 days of study vaccination.
  • Received, or plans to receive, licensed killed vaccines within 14 days of study vaccination.
  • Received, or plans to receive, immunoglobulin or other blood products within 60 days of study vaccination.
  • Received, or plans to receive, experimental drugs/vaccines within 30 days of study vaccination.
  • Received, or plans to receive, systemic immunosuppresive therapy, radiation therapy, or high-dose inhaled steroids within 30 days of study vaccination.
  • Use of systemic chemotherapy within 5 years prior to study.
  • History of Guillain-Barre Syndrome.
  • In addition to the conditions listed above, the following may qualify as a reason to exclude a volunteer from the study: fever along with moderate or serious illness within 3 days of vaccination or any condition that, in the opinion of the investigator, would render vaccination unsafe or would interfere with the study evaluations. Pending resolution of these symptoms, a volunteer may be reconsidered for vaccination.
