anthrax vaccine intramuscular




This vaccine is used to help prevent serious, sometimes fatal, infections caused by a certain bacteria (Bacillus anthracis) in high-risk people (such as military personnel, laboratory workers who handle the bacteria Bacillus anthracis).

This vaccine contains parts from Bacillus anthracis. It works by causing the body to produce its own protection (antibodies) against the bacteria.

How to use anthrax vaccine intramuscular

Read the Vaccine Information Statement available from your health care professional before receiving the vaccine. If you have any questions, ask your health care professional.

This vaccine is given by injection into a muscle by a health care professional. It is usually given as a series of 3 doses (1 and 6 months after the first dose), followed by booster shots at 12 and 18 months after the first dose, or as directed by your doctor.

This vaccine may also be given under the skin for certain people (such as people with clotting disorders, people taking "blood thinners"), although this may increase the risk of side effects. When given under the skin, this vaccine is usually given as a series of 4 doses (2 weeks, 4 weeks, and 6 months after the first dose), followed by booster shots at 12 and 18 months after the first dose, or as directed by your doctor.

Follow the dosing schedule closely for the vaccine to be most effective. To help you remember, mark your calendar to keep track of when to receive your next dose.

You will need a yearly booster dose if you still remain at risk for anthrax. Ask your doctor or pharmacist for more details.

Side Effects

Pain/redness/swelling at the injection site, limited arm movement, muscle ache, headache, or tiredness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Infrequently, temporary symptoms such as fainting/dizziness/lightheadedness, vision changes, numbness/tingling, or seizure-like movements have happened after vaccine injections. Tell your health care provider right away if you have any of these symptoms soon after receiving an injection. Sitting or lying down may relieve symptoms.
