The arrival of the Omicron variant, in particular, has rendered the vaccines far less effective at stopping the virus leaping from person to person. In most vaccinated people, mercifully, it is far less dangerous – the vaccines still do their job, imperfectly but effectively. But, as most of us are now aware, it’s very capable of infecting people, even triple-jabbed or previously infected people. In the Chivers household, all four of us caught Omicron within a few days last month, despite two of us being triple-jabbed and my son having already had it.
