Persons meeting these criteria must be at least 2 years post-myocardial infarction, cardiac bypass surgery, and/or percutaneous coronary intervention (e.g., angioplasty, stent placement, etc) in order to qualify. Persons with a history of cardiac disease must be under the care of a physician.~Exclusion Criteria:~Prior history of anthrax or immunization against anthrax; Known allergy to aluminum hydroxide, formaldehyde, benzethonium chloride, or latex; Pregnant/plans to become pregnant for duration of study/does not agree to use adequate birth control from the time of screening procedures to one month after last vaccination; Used cytotoxic therapy in previous 5 years; Cardiovascular disease with significant likelihood of progression over 5 years; Moderate to severe asthma, chronic obstructive pulmonary disease, other significant pulmonary disease; using high doses of inhaled steroids; Clinically recognized hepatic or renal insufficiency; Inflammatory, vasculitic, or rheumatic disease including systemic lupus erythematosis, polymyalgia rheumatica and rheumatoid arthritis, scleroderma; Known HIV, hepatitis B or hepatitis C infection; Other conditions known to produce or be associated with immune suppression; Neuropathy or other evolving neurologic condition; Unstable/moderate to severe mental illness; Ongoing drug abuse/dependence (including alcohol); Seizure disorder; Active malignancy or history of metastatic or hematologic malignancy; current diabetes; Anyone who plans to receive within 60 days of study entry: cytotoxic therapy, experimental products, a live vaccine outside this trial, immunosuppressive therapy, parenteral immunoglobulin or blood products; Anyone who plans to receive an inactivated vaccine outside this trial within 42 days after study entry;: experimental products, a live vaccine outside this trial, immunosuppressive therapy; Anyone who received an inactivated vaccine outside this trial within 14 days prior to study entry, parenteral immunoglobulin or blood products within three months of study. In addition to conditions listed above, temporary exclusion would result from moderate or severe illness and/or oral temperature \>100.4˚F within 3 days of injection or chronic condition that, in opinion of investigator, would render injection unsafe or would interfere with evaluations.
