I don't think it will be over night. Partly because of the 3 week lag for it to take affect, and partly they still need pressure on NHS to drop.
But I'm fingers crossed that they'll open schools for the first groups mid - end of February.
I doubt all years will be in before Easter but then the pressure will be on.
I guess England will be opened up by then, a little more organised with the vaccine, they pay more attention to the economies need, it will need the boost of trade at Easter, and Scotland has an election looming.
So I doubt she can keep Scotland locked up beyond England there again she might be on her 'keep everyone safe' mantra regardless of the other costs (financial, emotional etc)
