I did fine with the flu shot. Not a single issue...not even a sore arm.I had no effects from covid shot-arm sore when I woke up, but not later
Really glad I waited for the flu as that often causes a bit of a reaction
I'm feeling a tiny bit achy now ...headache and my eyes burn. But it's not an issue at all. It's no worse than what I feel on any given day when I'm a little off.
