I can only guess that it's a mix of the drive towards ending the 'pandemic situation' (see germany for example) and the easy brownee-points some politicians see in going with the train of 'I value lives over (money|...) And that's why I will add the new mandate for vaccines' etc. Or just a lot of pilled up anxiety, that's been collecting over the course of lockdowns.
