Huh, I didn’t even know there was a vaccine. We didn’t get it, but I remember an occasion in the early 70s when our whole school in Chula Vista, CA, was tested for TB, after a student was diagnosed.
The way I understand it, the new strain of TB can’t be beaten. It can sometimes to treated, though some patients still progress unpleasantly. But the patient will essentially be in prison for the rest of his life. It is very contagious, which is why the entire school was tested. Be thankful you tested negative.
