The problem now is they've tied themselves up in knots. My nan got her "booster" ( we all know in reality it's the third dose) about a month ago. Now she's in a flat spin. I understand why they don't want to diminish the effects of the vaccines because anyone with half a brain can tell we'd been in a far worse position without them. The issue though is that anyone with half a brain can also tell that they aren't as effective as we need them to be- and whether that's due to their design or because of the variants/the nature of this virus is up for debate.
So whilst we get light touch initial stories along the lines of "the vaccine is still amazing but a little top up never hurt anybody", these have now given way to "two doses no longer enough to be considered fully vaccinated and protection diminishes massively over time and against new variants". No wonder people are fed up.
