HI appleseed, i am meant to have this jab due to my asthma, and i personally would advise against it..the 2 times i've had it have made me really poorly..one of which set off an asthma attack. Also my friend who is a nurse says a lot of people she works around wouldn't touch it with a 10 foot pole. Obviously if you havent had a problem in the past i would go for it!!
