Question
How should the occurrence of diarrhea in children after flu vaccination be understood?
Answer
After receiving the flu vaccine, some children may experience symptoms such as low fever, headache, and fatigue. Sometimes, they may also have rashes, nausea, vomiting, and diarrhea. These are usually normal reactions, and parents should not worry excessively. It is important to ensure that the child gets plenty of rest, drinks plenty of water, avoids catching a cold, and maintains good nutrition. Generally, symptoms will resolve naturally within 1 to 2 days. If symptoms are severe, appropriate medication can be used. Additionally, the injection site may become red, swollen, painful, or feverish, which usually subsides naturally within 24 hours. However, if the fever persists, it is necessary to seek medical attention promptly.
