Interesting, I had my BCG back in '62, ahead of everyone else at school because of family members having had TB.
I had a school friend who was type I when I first knew her in first year seniors. She would have had her BCG maybe one or two years later and I remember she was still injecting insulin when we took our 'O' levels and 'A' levels because she was able to take her exams in a separate room. That alone doesn't prove anything.
I mention that because there must be lots of type Is who had their BCG in the years before the 2005 date mentioned in the report. I remember they tested first, then inoculated if they had to and that would have meant pretty much everybody.
