I have never had the flu vaccine ever in life, i now have to have it for nursing school, will i get sick since this will be mu fist dose of the shot?

Generally NO: ...But reactions may occur. You can not get the "flu" from the shot. The disease is usually much worse than any reaction. Do not hesitate!

Hard to know: In my personal experience with giving flu shots to many people, some who have had them always and some who get the first one. You might experience a slight fever and achiness with the first shot, but if you get them every year the you don't notice anything. Consider this if you do get a little bit sick, it will not be anything like what you would feel if you get the actual flu.
