AMBULATORY CARE:
The anthrax vaccine
may be given before exposure to anthrax bacteria to prevent infection. After exposure, the vaccine is given together with antibiotics to prevent anthrax disease. The vaccine helps your body create antibodies against the bacteria that cause anthrax. This vaccine is approved for adults 18 to 65 years old.
What increases your risk for anthrax exposure:

- You are in active military service.
- You plan to travel to a high-risk area.
- You are a farmer, veterinarian, or livestock worker.
- You are a medical provider or emergency responder and may be exposed to the bacteria through work.
How the anthrax vaccine is given:
- Before exposure , you will receive a dose in an upper arm muscle. Then you will get doses 1, 6, 12, and 18 months after the first dose. You will need booster shots each year you are still at high risk for exposure.
- After exposure , you will receive a dose into the skin of your upper arm. Then you will get doses 2 and 4 weeks after the first dose. You will also get antibiotics.
