Two years ago, an earlier lawsuit temporarily halted mandatory anthrax vaccinations for all 2.4 million service members and contractors. Two months ago, the defense department announced a reinstitution of the mandatory inoculation program. A class action lawsuit has been filed against the federal military alleging mandatory anthrax vaccinations are unethical and unsafe. The FDA approved the vaccine saying it was safe, effective, and not misbranded for protection against both skin contact with anthrax and inhalation. The lawsuit claims the FDA's certification of the vaccine is based on slipshod statistical analysis and an improper use of testing data. The military claims the inoculations are to protect members and civilians from aerosolized anthrax spores weaponries by terrorists or enemies of the United States. However, service members and contractors are threatened with termination from employment or criminal prosecution if they refuse inoculation. The case was filed in US District Court for the District of Columbia on behalf of all military service members and civilian contractors facing inoculation. BioPort Corporation manufacturers the vaccine.
