Good evening everyone reading this. I had been diagnosed with Ankylosing Spondylitis a few years ago. The range of motion and pain has progressed and limits my “military” duties. The reason for this post to see what can be done and what is known on the Anthrax vaccine and its relation to Ankylosing Spondylitis. I have had the Anthrax vaccine at least 8 times since 2002. I am AD and possibly entering into a MEB. Nobody in my family had this issue or anything similar. I have HBLA27 as well as showing on X-rays. Any guidance is appreciated. Thanks for reading.
