I had mine a few weeks back.
I have an auto immune disease of the liver.
Apart from a sore arm for a couple days , im ok.
Although last week, I did feel like I'd caught a virus or something, it felt like
I'd caught a cold, but wouldn't come out properly.
Don't know if that had anything to do with it or not, but the leaflet said that we start to
make our own antibodies 2/3 weeks after, and it was about that time.
I feel ok now though, lasted for about a week.
