In the past the shots were given but not listed on the booster sheet. It is important in case there are any side affects that arise. These vaccines are NOT well researched.
To be honest...nobody really knows effectiveness. From the FDA...
>>>Today, it would be difficult to repeat the efficacy studies. This is because there are no evident populations in the United States where prophylactic vaccine protection against natural exposure to anthrax could be evaluated in a clinical field trial, such as was done in the Brachman et al. study. Specifically, the incidence of naturally occurring anthrax in humans is low and sporadic in occurrence, making identification of a trial target population difficult. Likewise, it would be unethical to perform challenge/protection studies in humans. In addition, human immunogenicity and safety data would be required. The safety database obtained by CDC under the IND would be considered a reasonable pre-licensure database for evaluating a safety study today.<<<
http://www.fda.gov/ola/2000/anthraxvaccine.html>>>FDA has not had an official role in the development or operation of the Department of Defense's Anthrax Vaccine Immunization Program (AVIP), including the AVIP tracking system or the program's adverse event reporting system. In March 1997, DOD briefed FDA about their draft plan for the possible use of the anthrax vaccine to inoculate United States military personnel according to FDA approved labeling for six doses administered on a specified schedule over eighteen months. Subsequently, FDA learned that the DOD plan had been adopted.<<<
I have a brother who received a series of vaccines upon entering the military. Shortly after he began having seizures. They also found that he now has a small mass on his pineal gland and a thyroid problem. They discharged him with medical for the thyroid only, claiming that the other issues are preexisting.
