You cannot get the flu from the flu vaccine. It is an inactive virus. Yes you may get some side effects but it is NOT the flu. Also, if you already had the flu in your system then get the shot, yes you will get the flu, but you were gonna get it anyways. Flu shots are not made to make you sick so stop complaining, you do not get the flu from an inactive virus. That is all. I also put two sources, but feel free to look up more if you’d like.
