I lost you all after the first thread filled up. Good to find you all again!
Having caught up on this thread, (sorry didn't read thread 2) I have now downloaded the nhs app and my event trial pass appeared a few days later. This seems as much use as a chocolate teapot though really!
Thankfully I have no plans to travel abroad at the moment ... my passport ran out a few months ago anyway and I haven't got around to renewing it yet! 
In other news, I had a call from the lead consultant at my London trial site to say that she'd had to unblind me as they, essentially, had cocked up 
When I had the trial jabs, I had sore arm/tiredness type symptoms for 3 out of the four injections, with the fourth causing a big red rash on my upper arm that was sore and itched for over a week. It completely confused me and I thought I must have had the famed 'placebo effect'. Turns out that I had the vaccine last autumn and so should have had the placebo in March. They gave me placebo for injection 3 but vaccine for injection 4! So the reactions make total sense.
Anyway she kept apologising and said that I shouldn't worry and it will essentially be the same as having a booster this autumn. It does, however, make me think that I now can't jump ship and have a recognised vaccine which I would have been tempted to do if I needed to travel and I'm worried about if there is a general booster program linked to the flu jab and how that would work for me 
So many questions that I thought of after our conversation.
Glad to hear that some of you are managing to still stick to your plans and hoping that those wanting to go abroad will be able to do so.
