You cannot get the flu from the shot.
I think that is based on "current understanding," dear BB (peace to you!) as well as what the pharmaceuitcal and medical industries stand to lose if they admitted to the public that one could. The fact that so many say they DID get the flu just after getting the shot seems to indicate that one CAN. Maybe it's a different strain; maybe the shot triggers something dormant... but I have learned that when dealing with the medical industry, it's really not very prudent to say what will/will not occur or is/is not. Remember (1) there a populations that are the exception to EVERY scenario, even if a small minority, and (2) science is a process... and we don't have all the answers (not my assertion alone) - particularly in the medical field.
As for the OP, I've had two flu shots in my life, one after I was SO sick WITH the flu I ended up in the emergency room where they gave me one... and for which I ended up in the hospital for 3 days as a result of an allergic reaction (unrelated to eggs apparently - I am allergic to vaccinations in general - had never been before of ANY kind for that very reason and still haven't as to any other kind for that reason... and one a couple/few years ago that my doctor insisted on giving me because I am a diabetic (I tried to protest but he reacted as if I were the imbecile and not him)... where I ended up being the WORSE non-diabetes/other illness related sick I have ever known. Thought I was going to DIE. I even cried... and I'm not a crier.
Now, I'm gun shy. ALMOST did it earlier in the season this year, even sitting in the chair with sleeve rolled up. Just when they were getting the injection ready, though, I said "Uh-uh," and got up. Just couldn't bring myself to do it again after those two episodes. And hubby absolutely refuses.
I just went back to my usual way of dealing with it: antibacterial soap in all bathrooms, antibacterial dishsoap... and Lysoling and bleaching my house, which means spraying/wiping ALL knobs, handles, buttons, rails, fabrics, door edges, steering wheel, keys, keyboard, pens, phones... ANYTHING we routinely touch. And especially after the little people (elementary school age and younger family) visit. So, the toys we pull out for them, too.
So far... so good.
Peace!
