Explanation:

Detailed explanation-1: -The usual expected reaction to BCG vaccination is redness and/or a small lump at the injection site, followed by a small ulcer (open sore) a few weeks later (usually less than 1 cm in diameter). The ulcer may last from a few weeks to months before healing to a small flat scar.

Detailed explanation-2: -Within two to six weeks of the injection a small spot will appear. This may be quite sore for a few days, but it should gradually heal if you don’t cover it. It may leave a small scar. Occasionally, your baby may develop a shallow sore where they had the injection.

Detailed explanation-3: -Introduction. BCG, or bacille Calmette-Guerin, is a vaccine for tuberculosis (TB) disease. Many foreign-born persons have been BCG-vaccinated. BCG is used in many countries with a high prevalence of TB to prevent childhood tuberculous meningitis and miliary disease.

Detailed explanation-4: -BCG vaccine has a documented protective effect against meningitis and disseminated TB in children.
