Pediatrician,  's  Response
Thanks for the query.
Bacillus Calmette-Guerin destroys the cells (because it`was injected under the skin and not in the muscle) that's why it leaves a scar. The area will eventually heal modestly.
This is taken to be a sign of a ‘successful’ BCG vaccination.
However, sometimes the vaccine does not leave a scar even though the vaccine has ‘taken’ and will provide protection.
In such cases , a Mantoux test is offered. The Mantoux test involves injecting a small amount of a protein (“tuberculin protein”) into the skin with a needle and syringe.
And if the test is negative BCG vaccine may be repeated.
Hope i helped you.
