Blood type and side effects of vaccine?

[RedToothBrush]

Just a quick straw poll as we've been having this discussion at home and wondered if there might be something in it.

What blood type are you?
Did you get a lot of side effects from the vaccine?
Which vaccine did you have?

Hadn’t heard this theory.

I’m AB+, had Moderna, felt rough as fuck and had quite a lot of side effects after 1st. Some ongoing.
Still felt rough after 2nd but wasn’t any where near as bad as 1st and was short lived.

I suspect Ive had COVID, but don’t know for sure.

I'm AB+ had Pfizer and only had a sore arm both times.
