Question
A two-month-old baby has shown a significant decrease in appetite since last night after receiving the polio vaccine. Previously, the baby needed to be fed twice a night, but there was no milk consumption from last night until 7 AM this morning. Is this situation normal?
Answer
After vaccination, some children may experience symptoms such as fever, rash, vomiting, or reduced appetite. Typically, these symptoms resolve on their own within a few days. If the body temperature does not exceed 38.5 degrees Celsius, physical cooling methods can be used; if it does exceed 38.5 degrees Celsius, medication for temperature reduction can be considered. For regional redness and pain, a cold compress with a warm towel can be applied to help alleviate symptoms.
