Not sure totally true but irreversible means nothing.

Appears over October half term and Xmas holidays be optimum time.
When I think back to last year Wales 2 weeks circuit break dident do much good.
Neither did November mockdown closing businesses but keeping schools open.
We don't have any mitigating measures in place for school no distancing , masks .
No vaccination even 16 to and 17 year old won't be vaccinated in time.
Kids will be back from holidays with no need to quarantine.
They can also go schools if parent or siblings test postive.
This all sounds like a recipe for disaster especially we now being told double vax doesn't block transmission .
