I worry about schools this term, a lot return tomorrow and it is a long stretch now until May half term. Lots of staff and parents still aren't vaccinated. Primary school staff don't have much protection. If numbers continue to rise as indicated by boys charts we could be in for trouble.
I, too, have concerns about this, especially as the group 'of school parent age, and unvaccinated' will be mixing MUCH more post April 12th - and even more in the final part of this half term if the May re-opening step goes ahead - than was the case after the initial March school re-opening.
Hopefully, effects of seasonality, weather (more outdoor learning and less of a balance between ventilation and temperature) and ongoing vaccination rollout will mitigate this to some extent.
