Is it safe to take BCG vaccine twice?

Hi, I m due to get a bcg vacination on friday (I had the mantoux test today) and I have noticed a scar similar to the one the bcg leaves on my arm and I think I may have had the vacne before however it is not on my immunisation records, will it harm me to have it again?

Welcome to HCM.
No. it wont harm even if you have taken it second time.
But my concern is that it won't work now.
This vaccine is given at birth only.
Till now you must have been exposed to tubercular bacilli.
So, there is no point in taking this vaccine now.
If you have nay further query please ask me.
