As I recall, they were forcing U.S. Soldiers to take unproven Anthrax vaccines during the start of the Iraq War. They had to take them or be Court Martialed.
Mark Zaid, a lawyer who has challenged the immunization program, said there is no scientific proof that the vaccine is effective in human beings.
Meryl Nass, M.D., Director of the Military and Biodefense Vaccine Project (MBVP), said "America's military service members deserve to be fully informed about the deaths, chronic illness and disabilities that many soldiers have experienced following anthrax vaccination. The FDA-approved anthrax vaccine package insert acknowledges only six deaths and two dozen autoimmune diseases associated with the vaccine, but the FDA has not directed the manufacturer to update the insert in nearly five years. More than 1200 anthrax vaccine-injured soldiers have been treated at the congressionally mandated Vaccine Healthcare Centers, which DOD has attempted to close. They are suffering with crippling, life-altering illnesses that are being swept under the rug. We know the anthrax vaccine is reactive and we suspect it is especially risky for those with hereditary and other risk factors that DOD refuses to investigate or acknowledge."
Soldiers who refuse to be vaccinated may face a court martial. more
