So your OP has now moved from
"From September all teachers and CEV pupils should have been vaccinated, so we may as well just let it happen"
To "Even though CEV pupils won't have been vaccinated, we may as well just let it happen"
As expected.
I appreciate that it may not be practical to fully vaccinate all CEV children prior to the start of term, and recognise that part of my OP wasn't well enough thought through, but I don't really think it changes my point. For a parent worried about their CEV child, the numbers will be such that they may well look to keep them at home whatever measures are put in place.
My challenge to those who disagree with me is what they would do that would do anything other than prolong the agony. Short of requiring pupils to wear hazmat gear, pupils will be at an appreciable risk of catching Covid, especially Delta, in schools. You can delay the spread by mandating masks in classrooms or requiring bubbles to self-isolate, but that's only going to slow Covid's path.
A few years from now, unless we do literally require pupils to wear hazmat suits, most pupils will likely have been exposed to Covid... We can either:
a) suppress it hard over those years, continuing to disrupt education massively over this period time, with all the damage that does to children, and it wouldn't have prevent most children being exposed over that period, or
b) we recognise that Covid exposure is going to happen whatever we do, so we take measures that minimise disruption, and ensure that any disruption is focussed over a short period in the autumn, rather than extending, literally, for years.
