  • The flu vaccine does not contain live virus so it can not give you flu.
  • It is given once a year by injection to the upper outer area of the arm and it takes only seconds.
  • 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.
