I've been getting them since the heart attack back in '07, luckily never had a reaction.
But back a few years, I think it was '17 - I got nailed by the flu at the end of September. The week before I had a Dr. appt for a checkup and to get the shot - figures, doesn't it?
Gads it was a tough bout. BP went to h*ll, dehydrated, pounding headache, it took me down hard.
Time before that was in 1991, and that was a bad trip also.
Never have had the pneumonia shot - that I know of.
We got ours a couple of weeks ago, no reactions thankfully.
