Formation of scar is neither necessary nor is the only indication of success of BCG vaccine. However it is the only simple & convenient way of determining success of BCG vaccine. It may take 3-6 months for the scar to form. If no scar is visible at all after 6 months one needs to do Mantoux test. If negative, one should give repeat BCG
