Determining the consequences of hepatitis B vaccination after a child has jaundice depends on the type and degree of jaundice in the child. The first is that it will not cause significant adverse consequences in children. If the jaundice is very mild, or even physiological, with a relatively good mental state, and is only temporarily caused by more hepatic-intestinal circulation in the intestine, then vaccination with the hepatitis B vaccine will not cause significant consequences in children. Secondly, it can affect the aggravation of jaundice in children. If the jaundice is pathological, especially hepatocellular jaundice, vaccination with hepatitis B vaccine will often cause an aggravation of the jaundice level and may even cause liver function abnormalities to become more pronounced.
