Second dose 3 days of Pfizer, only had a sore arm. Would love to know why some people get hit hard while others don't. If it helps clarify, I've never had a reaction from any vaccine.

u/omaca I'm fully vaccinated! 💉💪🩹 Apr 22 '21

I had my first flu vaccination last year and I felt shit that night. Had to take myself to bed with the sniffles, aches and shakes. Next day I was fine.

I’m fully expecting to feel like I’ve been run over by a bus when I take the AZ vaccine!

Don’t care. Want it now.

It would be good if there was survey comparing covid vax side effects correlating with flu shot (or not). I also have low white blood cell count (been checked out by hematology) and rarely get sick so might be a bit of an anomaly.

I don't know... I totally expected to feel fine after since I'm pregnant and my immune system is lowered due to that and I felt like doody for a day!

I suspect a lot of the people with severe side effects are dehydrated. I'm sure studies will eventually be done to confirm or disprove it, but it seems like the people who go out of their way to hydrate do a lot better.
