MGH launches phase II trial of [100yo] BCG vaccine to reverse type 1 diabetes

I've seen BCG described as cave man immuno-therapy for bladder cancer and other apps... it will be interesting to see how it works for diabetes and MS.

Presumably someone has looked at rates of those types of diseases in Eastern Europe, where BCG was used a a vaccine for TB for years.... but I have no idea if it worked preventitively.
