Question
The child received the H1N1 influenza vaccine a week ago and has been experiencing facial redness since then. The symptoms have persisted for a week. Have there been any previous treatment experiences and their effectiveness? What kind of assistance is needed now?
Answer
After receiving the influenza vaccine, common local side effects include pain, redness, and itching. Systemic side effects may include fever, fatigue, headache, nausea, and more. These symptoms are typically mild and usually disappear within 24 hours after vaccination. It is advisable to consult the precautions before vaccination, which usually suggest waiting until after a fever has recovered before receiving the vaccine, depending on individual circumstances.
