Please how long will someone repeat bcg if it did not show any lump or scar?
Sometimes the BCG is given too deep instead of into the skin. Usually to confirm in case of no BCG scar, we will do a mantoux test to see if there is a reaction expected for someone who has had BCG. If there is none after 72 hours, we will give the BCG again as long as child is healthy(a normal Chest Xray may be needed at times)
