Some people may experience mild side effects following vaccination, such as:
- drowsiness or tiredness
- muscle aches
- localised pain, redness and/or swelling at the injection site
- occasionally, an injection-site lump that may last several weeks
- low-grade temperature (fever)
These side effects are usually mild, subside within a few days and do not normally require treatment.
More severe immediate adverse effects, such as hives or anaphylaxis, are very rare consequences of influenza vaccination. Your pharmacist is trained to recognise and manage any immediate, severe reactions.
Your pharmacist will also carry out a pre-screening assessment before vaccinating you to ensure the vaccine is suitable for you.
