They are worried about people going nuts this summer and meeting hundreds of people to make up for the last year.
They are concerned about the Eeek variants (the SA one and the home grow mutated kent variant which has popped up in Bristol and Liverpool).
They really want to keep a lid on it whilst we get the vaccine out there (remember lots of the population wont get a first shot until june or july and there is still a second one to go) and they want a variant adapted jab to be on the cards.
If you were keen to avoid a repeat of last year and how going into autumn things went tits up very quickly, youd have your finger over the button of very localised shutdowns which were very hard and strict. And youd discourage massive parties and meet ups into 2022. Thats not 'don't see friends and family', more dont see everyone and his dog, the neighbours and all their mates and the mates of all the family at the caravan next to yours.
Its expectation management as much as anything. We are going to be told to be sensible rather than losing the plot (this is the uk. Lots of people are going to lose their minds this summer).
Personally ive booked something less than an hour away which is unfashionable. I really just don't want to have to deal with the huge number of people who are going to act like bellends this summer.
I want time away, but the thought of going to Cornwall like everyone else and getting stuck in the mother of all traffic jams - and considering the limited hospital facilities there - na no thanks.
