To be clear, that's why I think we shouldn't be sending children back to school. We don't have workable solutions to mitigate risks for pupils , teachers, other staff or the wider community.
And if we never have a vaccine or if any vaccine that is produced isn't 100% effective? What then? We never send them back?
Ok. That sounds workable.
It's a virus which is extremely low risk for children and healthy adults. There is clear data showing that. Those with chronic health problems and the vulnerable grandparents who it does pose a risk to are the ones who need shielding and protecting.
