Vaccination is not recommended when your baby has diarrhea. This is because when a child has diarrhea, it is most often a combination of bacterial or viral infections that cause the symptoms. At this time, the child’s immunity is reduced, and if the baby is given the vaccination, other undesirable symptoms are likely to occur. It is recommended that your child not have a history of colds, fever, runny nose, cough, diarrhea, or other special types of medications within a week before the vaccination. If your child has any of these uncomfortable symptoms, it is recommended that he or she be actively treated and that the child be considered for a follow-up vaccination only after he or she has been cured for at least one week. If a child develops a fever or rash after vaccination, it will usually subside within 2-3 days. If your child’s fever recurs and exceeds 39°C or if the rash tends to worsen, you should take your child to the doctor as soon as possible for examination and symptomatic treatment.
