I got my flu shot 1 1/2 weeks ago. It didn't cause a flare. I don't recall them ever causing me a flare. This past spring and summer I've had more flares than usual, but from other causes - lack of sleep, stress, family changes, etc.

I get one every year with no flares or side effects.

Wish it had been out sooner currently have the flu and can't get the shot until my body clears it from my system = a good month or so from now the way my immune system is.

No flare from the flu shot

I just got my flu shot yesterday around 3 o’clock. I usually get a flare 24 hours after I get the vaccine. This is my eighth flu shot in a row due to being forced to get it as a nurse working in the hospital. I am now retired but I continue to get the vaccine only because suffering one day of hell is better than getting the flu. I have never been sick one day since I have had fibromyalgia.
Wish me luck! Maybe this year I won’t have a flare. That would be a miracle.
