The BCG (Bacillus Calmette-Gu?rin) vaccine is a preventive vaccine that protects against tuberculosis, particularly in young children. It is usually given shortly after birth, often within the first few days of life. The vaccine works by stimulating the immune system to recognise and fight the tuberculosis bacteria if exposed later.

It is best to consult your paediatrician first for a bilirubin blood test to assess the jaundice. If the jaundice is mild and resolving, and your baby is otherwise healthy, the BCG vaccine can usually be given safely. If the jaundice is severe or your baby is unwell, the vaccination should be postponed until your doctor confirms it is safe to proceed.
