Description : Do all Mexicans (born in Mexico) have the tuberculosis vaccine scar on their arm?
Last Answer : I have no idea if all Mexicans get it, but I have it and I was born in the US. When I was about 4 or 5, that had this thing like a vaccine gun. We went to the firehouse, lined up, and they ‘shot’ us all in the arm with multiple vaccines all at once. I’ve been told it looks like a pipe burn.
