hi doctor, my baby is around 1.5 month old and my problem is that i have noticed a oyster on her left hand. when i enquried about that they are telling that this oyster is becausr of BCG vaccination.is it true doctor

A. That usually happens because of the same only but in most of the cases it is like an infection which burst out after a while but if you are seeing only an oyster thing it is not a problem and if your doctor has checked and confirm then you can go buy it
