Can you provide reasons to have it?
My wife got it, my daughter didn't.
It is not given in the US. (not required) The only thing I know for sure is that people who do get it will show a positive result on a TB tine skin test. Then they must get an xray to verify that they indeed do not have Turbuculosis. TB is less of a threat in the United States, and because of the
potential risk of side effects from the vaccine, it has not been
included in the recommended guidelines. So while I can not say that your child will not contract TB, I also do not think that the risk of TB is that high to most "mixed" children.
That is my opinion on the matter only.☝
