We've just been in Israel where they have the "Green Pass" system - it's like a vaccine passport; scan-able QR code that you present to enter venues, attractions, restaurants and cafes.
Mask wearing is mandatory in all public indoor areas unless seated and on all public transport. In fact the only people we saw not wearing masks were two British Tourists on a Tram.
Their lockdown guidance has always been well published (none of this "interpret how you would like to" nonsense that we've had to endure... And their contact tracing system is phenomenal.
This isn't solely to blame the UK Government but I am so sick of hearing people saying they've done an awesome job. They simply haven't, particularly with the mask wearing fiasco.
Tube yesterday and half the carriages on two journeys and at least a third on the other two journeys were not wearing masks, and made no attempt to socially distance themselves from mask wearing passengers.
