I can imagine quite a worrying scenario playing out. The variant could well be used as an excuse for delaying easing until all adults have been offered the vaccine. At that point, the government might turn round and ease everything but implement vaccine passports. They still get to be the knights in shining armour who saved the summer to much media fanfare, but they also get their pet project in.Indeed - continuing with the 'divide and rule' tactics we've seen all along, we can turn on each other and not direct our anger where it should be going.
Also this wave of propaganda against the unvaccinated, stirring up fear and anger and 'othering' them, is going to be an oh-so-convenient hook for Michael Gove to roll-out his domestic vaccine passports in a few weeks time.
After all, if they want to roll out vaccine passports they'll find it much easier to do this after all adults have been offered the vaccine. I seem to recall a poll from a while back showing a 15 point increase in public support for passports if they're done after that point, any legality issues around indirect age discrimination wouldn't apply, and it would be less likely to inflame tensions among young people. Delaying it slightly also gives them time to actually finish the app, since as I understand it the technology has taken longer to develop than they expected.
