Both my kids were VERY premature and have had the fly shot every year, neither have been sick with the flu or had but 1 or 2 days off from school in past years. My daughter did get the H1N1 virus 2 years ago when there was an out break, she was VERY sick and you can catch it again so she will also be getting that shot. This is truly a personal choice, especially when it comes to the flu shots but H1N1 can kill so we will go with the shot after seeing what the virus it can do first hand, and she only had it mildly.
