After being advised of the identity of the interviewing agents and the purpose of the interview[ |provided the following information: a project aimed at evaluating the feasability of conducting a dry aerosol Bacillus anthracis (Ba) bé vaccine challenge was initiated. The purpose of the study was to bic determine the breakthrough point for the recombinant protective antigen (rPA) Ba vaccine, in other words, what concentration of Ba spores would cause the vaccine to fail. Using the wet aerosol systems in place at the time, a high enough concentration of Ba spores could not be achieved. However, generation of a dry aerosol of Ba spores was expected to provide a sufficient concentration of spores thus achieving this breakthrough point. Additionally, a dry aerosol more closely resembles the type of Ba exposure a soldi on the battle field would likely encounter. For these reasons f felt that to demonstrate the true efficacy of the vaccine, they needed to evaluate it against this more applicable threat. [__Jindicatea that the dried aerosol project never got off the ground. Some equipment was purchased and only preliminary experiments were performed using inert dusts or avirulent simulants. and as a result, the dry Discussions about possible sources for dried Ba took place. Specifically, discussions as to whether spores would be produced at USAMRIID or obtained externally through DUGWAY PROVING GROUND ensued. recalled no discussions with other dey producing dried Ba.
