Every day the vaccine rolls out

[Yeats 62]

I thought under current rules that any home contacts were to isolate for 10 days, hence why there are so many self isolating just now?

There was an add-on to that Chick last few days. Lots of bullet points etc. But double jagged and boosted can go back to work after a negative PCR test. There are more scenarios, but it left things too open for ambiguity (if that's a real word) It can be abused if required.
