It was routinely given in my generation - we all have the "BCG" mark. As I said above - TB in cattle (given that milk is routinely pasteurised) presents almost zero health risk to humans and indeed the cattle can be immunised effectively - other than by EU rules (sigh).
Over here most of my generation (the Baby Boom) has the scar from the smallpox immunization. We all got it in the 1st grade but now smallpox has been eliminated except for stores kept for research.
