Is flu vaccination safe in children?

Vaccination trains the immune system to recognise influenza without giving the child influenza infection from a multiplying vaccine virus. Mild soreness, tiredness or a low fever may follow and usually settles without special treatment. The available product may depend on age and medical history. Vaccination reduces the chance of flu illness but cannot prevent every cough, cold or fever caused by another infection.

Tell the vaccinator about severe allergies, a previous reaction to a flu vaccine, immune problems, medicines, and whether the child is currently unwell. Keep the child comfortable, offer normal fluids and follow the clinic's advice for discomfort. Do not give a medicine solely to prevent a reaction unless a clinician has recommended it. Keep a record of the product and date for future appointments.

Seek emergency help if the child develops difficulty breathing, swelling of the lips or throat, widespread hives, collapse, or unusual unresponsiveness after vaccination. Contact the child's doctor if fever is persistent or the child is becoming more unwell, drinking poorly, or breathing faster than usual. A mild sore arm alone is usually managed with observation and comfort measures.

Ask which flu vaccine suits the child's age, whether a past allergy changes the plan, how to manage expected reactions, and when the child should return for any recommended follow-up dose.
