Mode of transmission of the anthrax disease are through wounds, the pharynx, gastrointestinal tract, the digestive system after ingesting spore contaminated food or water, skin lesions or abrasions caused by biting flies and the breathing in of air containing anthrax spores.
Prophylaxis played a prominent role in controlling anthrax in animals and protection to individuals from infection. Several vaccines has been produced for the anthrax disease. Louis Pasteur is known as the first microbiologist to produce the first anthrax vaccine in 1881.
Different methods have been adopted to create an enhanced vaccine for humans. The objective is to develop a vaccine that is non reactogenic and involves little administration to perform efficiently.
