Female infant, 1 month old, jaundice index around 12: Yesterday received a vaccine shot: Will there be any effects? The child’s jaundice index is not very high. The hepatitis B vaccine can be administered without affecting the body. Guidance: It is recommended to observe the child’s condition more closely. If the jaundice becomes pathological jaundice, symptomatic treatment is needed. The key is that the infant received the injection in the afternoon and came back in the evening to find that they had diarrhea. This could be due to the hospital prescribing Yinzhi Huang oral liquid. After drinking it, they may experience diarrhea and mistakenly think they have a cold.
