End in Tiers?

So, the "end of lockdown" tiers have been announced, but no one knows which one they're going to be in yet. We're hoping that we're going to be a T1 kind of place next week, allowing family to visit etc., but we're on the borderline in terms of infection rates so could be a T2 if unlucky. Good news about the various positive vaccine results popping up now though, Science to the rescue! The mRNA techniques used in the Pfizer and Moderna products are really interesting, something that may bear tremendous fruit in years (and future pandemics) to come, just need to sort out the cold-chain constraints. I have a couple of good friends in the "Pharma biz" on the scientific side of these efforts, they seem very optimistic that they (we) can get these jabs distributed quickly (and that's not "corporate happy-talk") Let's hope nothing untoward springs out of the woodwork between now and the safety sign-off in a few weeks time..
