I received my very first one yesterday during my check up. I've always hesitated getting one because they always made my mother sick. So far, I've had no side effects, just a little soreness at the injection site.
I got the flu shot and the Covid booster on the same day. The next day, I felt awful. But figured I'd rather have 1 day of feeling crappy vs. 2 separate days.
The only time I had an issue with it was the first one I ever got years ago made me sick. I've never had any issues since and have gotten one every year for a long time.
So glad you are having no reactions.
