First and foremost,
The vaccine will NOT give you the flu!
However, like all vaccines, there may be some side-effects - most of which are pretty mild, and usually subside within a few days:
- Soreness, redness, swelling and pain at the injection site
- Drowsiness, Tiredness
- Muscle aches
- Slight Fever
All these symptoms are usually managed either without treatment or with paracetamol. If you experience any of these symptoms and they DON'T improve, contact your GP.
But most importantly, the MAIN side effect is that
YOU WON'T GET THE FLU.
