Biothrax
Biothrax is a vaccine that lowers your risk for getting anthrax from a bacteria called Bacillus anthracis (B. anthracis). You can get the vaccine before you go into a setting that exposes you to B. anthracis or after you've already been exposed to the bacteria. It's given as an injection into the muscle or under the skin. This vaccine is only recommended for people who are at high risk for getting anthrax, such those who work in laboratories that study B. anthracis or certain military personnels.

Pharmacist tips for Biothrax
- Make sure to mark the dates on your calendar of when you need to go in for all your Biothrax injections so that you stay fully protected against anthrax.
- If you're at risk for or have gotten hematomas in the past with injections into your muscle, you can ask your provider to inject Biothrax under the skin.
- The stopper of the Biothrax contains natural rubber latex. Make sure to notify the provider giving you the vaccine if you're allergic to latex.
- Wait until you're healthy to get Biothrax. This will help make sure your immune system protects you as best as it can. If you have a mild sickness, such as a cold, you might still be able to get Biothrax. But if you feel moderately to severely sick, wait until you recover before getting this vaccine. Ask your provider if you're not sure whether or not you can get this vaccine.
- Make sure to keep a record of all your immunizations and show it to your provider or pharmacist before receiving any vaccine, including Biothrax, to make sure you're receiving all your vaccines on schedule.
- Read the vaccine information statement for more information on Biothrax.
- If you experience a severe reaction to Biothrax, you or your provider can report it to the vaccine adverse event reporting system (VAERS) website or by calling 1-800-822-7967.
Risks and warnings for Biothrax
Biothrax can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Severe allergic reactions
- Risk factors: Latex allergy | Allergic reaction to other vaccines
As with any vaccine, there's a rare chance that you might have a severe allergic reaction to Biothrax. Your risk is higher if you're allergic to latex because the stopper of the vial contains natural rubber latex. Your provider might ask you to stay at the pharmacy or clinic for a short period of time after you've received your vaccine to make sure you can get proper care in case of a serious allergic reaction. Sometimes, these reactions can happen after you've already left the clinic. Get medical help right away if you notice symptoms of a severe allergic reaction, such as feeling faint, swelling of the face, closing of the throat, difficulty breathing, hives or rash, dizziness, shaking, nausea, or chest pain.
Birth defects
- Risk factors: Currently pregnant
Biothrax can cause harm to unborn babies when administered to a pregnant woman. Due to this risk, it should only be given to a pregnant woman if the benefits are greater than the risks. Talk with your provider if you're pregnant or thinking about becoming pregnant to see if this vaccine is an option for you.
Lower response to Biothrax
- Risk factors: Medical conditions that weaken the immune system | Taking medications that lower your immune system
Biothrax might not work as well in people with a weakened immune system. This can put you at higher risk of anthrax infection, even after you've received the vaccine. If you have any medical conditions (e.g., HIV (human immunodeficiency disease) or cancer) or take medications that weaken your immune system (e.g., high-dose corticosteroids or transplant medications), don't get Biothrax until you've talk with your provider first.
Maintain necessary precautions
Just like all vaccines, receiving Biothrax doesn't guarantee that you won't get infected with B. anthracis. For the best protection against anthrax, you should receive Biothrax as well as take all necessary precautions to avoid exposure to B. anthracis if you're exposed to it in your work setting. It's also recommended that you be aware of regulations and restrictions concerning the importation of prohibited animal products, trophies, and souvenirs. Refer to the CDC yellow book for more information.
