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.
The production of two powerful exotoxins and lethal toxin by the bacteria causes death. Veterinarians can often tell a possible anthrax-induced death by its sudden occurrence, and by the dark, nonclotting blood that oozes from the body orifices.
However, the difficult aspect of checking the potency of anthrax vaccine is making an assessment in humans. Tests using this pathogenic bacteria is not safe for humans and animals and requires special precautions.
