Six complainants, remaining unidentified to protect them from retaliatory military discipline, filed suit against federal military and health officials Wednesday in U.S. District Court for the District of Columbia. They are asking a judge to once again declare the controversial vaccine an unapproved drug and unlawful for use without informed consent.

Each of the plaintiffs faces either termination from employment or criminal prosecution if they refuse inoculation. The lawsuit is part of a class action on behalf of all military service members and civilians facing inoculation, supposedly to protect them from aerosolized anthrax spores weaponized by terrorists or enemies of the United States.
