Researchers have developed a nasal vaccine that protects against anthrax.

A vaccine for anthrax already exists, but can only be delivered through injection.

The developers of the nasal vaccine believe that it will serve as added protection against the anthrax bacterium.

With the increasing use of anthrax as a biological weapon, the researchers believe this vaccine will be useful to military personnel in high risk areas.
