I take the flu shot every year and have never gotten the flu, untill 2 days ago and right now I am pretty sick. However I firmly believe I would be a lot sicker if I didnt take the shot. my grown kids do not take the shot and they have had all been down with a flu bug twice seems it barly goes away and it comes back again I am not even sure I have the flu as i do not have a feaver I have a cold on my left side but right side of face dont even have a sniffle I ache all over but some of pain is muscle pain and fibro My chest aches could be from comprimised ling disease or flu However I am glad I got the shot because I know it could be a lot worse
