In case of physiological jaundice, vaccination can be given when the jaundice value is below 8mg/dl, which does not have a great impact; however, in case of pathological jaundice, it is recommended that vaccination be given when the jaundice value is below 5mg/dl to avoid affecting the resistance. Physiologic jaundice usually appears 3-7 days after birth and completely subsides in about 14 days, and the time for jaundice to fade can be shortened if sunlight is received during this period. Patients with normal physiological jaundice do not need to worry too much about vaccination if their bilirubin values are not high, as jaundice is not a contraindication to vaccination. If the jaundice is caused by infection, the jaundice value needs to be reduced to less than 5mg/dl before vaccination can be given, otherwise it may aggravate the jaundice and even cause liver function damage. In addition, because reasonable home care can prevent further jaundice, parents are advised to master certain care measures to make jaundice subside as soon as possible, such as keeping stools open, strengthening skin care, avoiding infections such as umbilical cord infection, diarrhea, pneumonia, and proper sun exposure.
