From the Vaccine Information Statement that you were asked to read before you received the shot:
What are the risks from anthrax vaccine?
Getting anthrax disease is much more dangerous than any risk from the vaccine. Like any medicine, a vaccine is capable of causing serious problems, such as severe allergic reactions. The risk of anthrax vaccine causing serious harm, or death, is extremely small.
Mild Problems
• Soreness, redness, or itching where the shot was given (about 1 out of 10 men, about 1 out of 6 women)
• A lump where the shot was given (about 1 person out of 2)
• Muscle aches or joint aches (about 1 person out of 5)
• Headaches (about 1 person out of 5)
• Fatigue (about 1 out of 15 men, about 1 out of 6 women)
• Chills or fever (about 1 person out of 20)
• Nausea (about 1 person out of 20).
Moderate Problems
• Large areas of redness where the shot was given (up to l person out of 20).
Severe Problems
• Serious allergic reaction (very rare - less than once in 100,000 doses).
As with any vaccine, other severe problems have been reported. But these events appear to occur no more often among anthrax vaccine recipients than among unvaccinated people. There is no evidence that anthrax vaccine causes sterility, birth defects, or long-term health problems. Independent civilian committees have not found anthrax vaccination to be a factor in unexplained illnesses among Gulf War veterans.
What if there is a moderate or severe reaction?
What should I look for?
Any unusual condition, such as a severe allergic reaction or a high fever. If a severe allergic reaction occurred, it would happen within a few minutes to an hour after the shot. Signs of a serious allergic reaction can include difficulty breathing, weakness, hoarseness or wheezing, a fast heart beat, hives, dizziness, paleness, or swelling of the throat.
What should I do?
• Call a doctor, or get the person to a doctor right away.
• Tell your doctor what happened, the date and time it happened, and when the vaccination was given.
• Ask your health care provider to file a Vaccine Adverse Event Reporting System (VAERS) form if you have any reaction to the vaccine. Or call VAERS yourself at 1-800-822-7967 or visit their
