It seems like a logical step so like it or not it may well be coming.I tend to agree with your implied cynicism regarding politicians vs scientists, however.... if 1 dose of Pfizer-Biontech gives 91% protection, 2 doses of Oxford gives 60% then it's an interesting suggestion.
I'm less keen on the "health passport" idea as that seems like the thin end of particularly unpleasant wedge.
No harm having some thoughts on all of this. Throw up ideas, see which have merit.
