I thought the changes after 9/11 sucked, we haven't seen anything yet with long term implementation for this mutating virus. It's not going away obviously with the new E484K strain, so where does that leave us? Tracking and tracing, immunity passports, isolating, further class separation, back to nature to pass time for entertainment instead of socializing? At this point it is anyone's guess.
I did get my first Moderna shot and a card that I will laminate after the second shot is recorded. Two forms of proof may become standard. The hard copy as backup to electronically if you don't charge your phone battery. I do hope they have made some in-roads in Europe to mass use of the QMC HealthID App. I couldn't find anything on the net to confirm that. Time will tell if this becomes a stepping stone to all your medical records being recorded in the future.
