I'm a bit lost, here. Could do with some advice, please.
I'm double jabbed but don't really want to get the booster but going to Spain on the 18th. As the time has passed for the double jab to be suitable, I need to have a negative antigen within 24 hours of flying/arrival, whatever.
That's where I'm lost. How do I physically show the results of my antigen in that time frame. I can get to the bit of having the negative in my hands but after that ??
Any help welcome
