Folks before getting a flu shot, I suggest going and getting a clue shot first of what you are actually getting. Those shots are questionable for all that they help in any way and for the old it is found they are sometimes worse than not getting one. The last one I took was when I was 33 and it made me sick for three weeks and missed work and took a long time to recuperate, have not taken one since, 81+ now and haven't had the flu since, a few minor colds is all. My wife and all around me have but I didn't. I must stay far away from taking one of them.
Now some are threatened of being fired if they don't take it. Where has our right of freedom gone to anyway, sad day we've come to, I'd say.
