A one-month-old infant with diarrhea received a vaccination.

Patient's question:

Patient Age: Full Moon, 33 Days
Condition Description: Hello Doctor: My baby was just born and is now 33 days old. Today, we took him for a vaccination, and after coming back, he had a bowel movement on the floor, which seemed a bit like diarrhea. A check on the stool indicated enteritis. Has the vaccination caused the diarrhea, and what impact will it have on his body? Since we have been using diapers, the stool seemed okay, but when it got on the floor, we realized it was quite loose and a bit like diarrhea.
History of Treatment and Effect: Taken Wangshi Baoci Pills
Desired Help: I want to know what effects the vaccination will have on the body, especially if he has diarrhea after getting vaccinated, or what kind of situation might occur?

Doctor's answer:

A newborn infant with diarrhea who has received a vaccination? In principle, infants with diarrhea should not receive vaccinations. Diarrhea in infants is likely caused by an infection, and during an infection, the baby's immunity is weakened, making vaccination inappropriate. It is recommended to wait for 2 weeks after the diarrhea has been cured before administering vaccinations. First, it is necessary to identify the cause of the diarrhea. If it is acute infection such as gastroenteritis, vaccination should not be administered. If the cause is other factors, such as lactose intolerance, it will not affect vaccination.
