VitreousHumour I separated them according to the health condition, which is in the "vulnerable" category that about 15 million share,
not the shielded 1 million or so.
An adult family member with those vulnerable conditions - unless they are say 70+, which is a whole higher risk in itself -
won't be at sufficiently serious risk to outweigh the benefits to the child of attending school
However, someone who is shielding because of more serious conditions might reasonably decide the risk is too high
The country can afford to support 1 million to stay at home, until a vaccine if need be
However, the 15 million merely vulnerable do need to quickly get back to work / school
