What protection does immunisation give against anthrax?
A. Independent medical advice confirms that immunisation provides effective protection against anthrax used a biological weapon. The immune response in individuals varies but significant protection against anthrax is normally provided following the third injection (i.e. after six weeks). Peak protection occurs soon after the fourth dose, six months later. However, no vaccine provides 100% protection which is why we use immunisation in concert with other protective measures against biological weapons.
