There is no sign of bcg on my 3 month old baby arm. Do I need to take him back for another one?
Sometimes the BCG is given too deep instead of into the skin and at times it might not show for whatever reason. 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 X ray may be needed at times)
