In general, vaccination can be carried out normally when the jaundice value of the baby is 9 mmol/L or less at full term, and vaccination can be carried out normally when the jaundice is breast milk-based. If the jaundice is progressively aggravated or recedes but reappears, and if it is accompanied by abnormalities such as poor reaction, poor milk intake, and gradual lightening of stool color, vaccination cannot be given, and the baby should be examined at the hospital in time and given appropriate treatment if necessary. In the case of breast milk jaundice, in addition to good skin staining, good reaction and feeding, bright crying, and good weight gain, most of the skin staining can subside in about 40-50 days, and it does not affect the normal vaccination process.
