is done in her lab's web site, is a mistake. The experiment used CFA, which is
toxic. Or is there something I'm missing? Does someone know why Faustman's
web page refers to this treatment as non-toxic? Is there something about her
formulation or dosing that makes it safe? (This question has nothing to do with
the safety of Faustman's current clincial trial, because that trial uses BCG.
From a safety point of view, BCG and CFA are quite different.)

I think by non-toxic they meant a doseage that was not known to cause the toxic
side effects... Also, she has made a point of telling folks that part of the
research is to find a human tolerable replacement for CFA.
