What is the most effective weapon against anthrax?

The most effective weapon against anthrax is vaccination, particularly the anthrax vaccine adsorbed (AVA), which provides immunity to individuals at high risk of exposure, such as military personnel and laboratory workers. In the case of exposure, post-exposure prophylaxis with antibiotics like ciprofloxacin or doxycycline is crucial to prevent the onset of the disease. Additionally, ensuring proper biodefense measures and rapid response capabilities are vital in managing potential anthrax threats.
