- The flu vaccine is not a live vaccine so it cannot give you flu.
- The vaccine will not cause an exacerbation or flare up of your symptoms.
- It is given annually by injection to the upper outer area of the arm and it takes only seconds. The injection itself is not painful.
- Possible side effects include pain, swelling and redness at the injection site, also occasionally slight fever, shivering, headache and aching muscles.
- These symptoms usually disappear within one to two days without any treatment.
