TBH, I think the media are loving talking this into a doom-fest.
I absolutely understand that people are disappointed because of travel rules and changes etc, but I do feel they need to happen at this point because of the uncertainty. The government are really damned if they do, damned if they don’t. Because if they did nothing and omicron turned out to be lethal then it would be too little too late, and now that they’ve acted quickly it leads to disappointment on a different level.
But the truth is that omicron is still the unknown. There is as yet no evidence that it is vaccine resistant, or more deadly, in fact evidence thus far is that this particular mutation has damaged the virus and weakened it and that this could in fact be the beginning of the end. We’ve had only 165 cases in the UK so far, in a population of 60 million people, and while of course omicron could become the most prevalent strain, it equally might not. Only time is going to tell.
But the media are all out there working on their panic-grabbing headlines “expert says the next pandemic could be more deadly,” well, it could, but it could also be in 150 years time, but let’s not let that possibility stand in the way of a good bit of panic-mongering on the part of the press.
I’m sorry for anyone whose travel plans have now been altered, and hope that this time next year things will be more normal and less stressful.
In the meantime I would stay away from the press, and as much away from COVID talk as possible, and do hide that ghastly COVID topic…. 
PS: a good anagram of omicron is moronic.
