Firstly, it will not cause obvious bad consequences for children, if the degree of jaundice is very mild, or even belongs to physiological jaundice, the mental state is relatively good, and the jaundice is only temporarily caused by more hepatic and intestinal circulation in the intestinal tract, then the vaccination of hepatitis B will not cause obvious consequences for children. Secondly, it will affect the aggravation of jaundice in children. If the jaundice belongs to pathology, especially hepatocellular jaundice, after receiving hepatitis B vaccine, it will often lead to aggravation of the level of jaundice, and even cause liver function abnormality to become more obvious.
