If untreated, however, all types of Anthrax disease can be life threatening. The vaccine is recommended for people who have occupational exposure to animal hides, furs, wool and animal hair, as well as individuals such as veterinarians or livestock workers who may come into contact with anthrax spores. Also, because of the threat of biological warfare, military personnel should be vaccinated. Mild local reactions occur in one third of those vaccinated. These reactions include soreness and redness at the site of injection.
Reactions including severe swelling of the injection site and flu-like symptoms are rare.
