I can't speak to the toxicity of the dosage used in the trial mice. When I spoke
with Dr. Faustman at some length (see DiabetesDaily interview) she mentioned
that CFA was toxic to humans. This was in the context of discussing whether a
single dose of BCG would 'cure' diabetes. She said that in mice CFA seems to be
a permanent cure with a single dose. But to develop the same for humans would
require new drug development.
I suspect (not from talking with her) that if BCG works, we'll end up taking a
dose of BCG on a regular basis in place of insulin. But we won't need to test
our blood sugar. I'd inject daily if I knew that highs and lows were gone. That
would be a huge win for me.

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.)
