We're part of the Salford trial. Had our 2nd jab yesterday - wow, does my arm hurt today. :-)
I had an achy arm after the 1st jab, bit of a headache and an 'off feeling'. Jab two yesterday - headache within an hour and this time my arm is really sore, right down to my hand, and warm at the jab site. The 'off' feeling is back, as well.
I normally get a little bit of an ache with things like the flu jab, and round one was about that level - there but mostly ignorable, nothing to mither about. This, on the other hand, is as my grandma would have put it, 'properly uncomfortable'. Both times my blood pressure did weird things afterward, as well.
My husband, injected at the same two appointments, has had nothing at all both times. He's determined that this means I've had it and he hasn't - I'm not ruling out the placebo effect, personally.
Our syringes were identical, clear with and labelled for both active/placebo, so no clue there.
We were both antibody negative before hand, although our 10 year old was positive (different testing thing a few weeks ago.)
