Foxinascarf, I'm not sure that's true. I don't think anyone here is ignoring teachers and TAs.
There is a lot of pressure on the government to collect data on how this is affecting adults in schools - amazingly, there is no data on that at the moment!
There is also pressure building for vaccination of all those in schools, including adults.
Obviously, the case for that relies on data. At the moment, we have no idea if adults (& which adults) are at greater risk than the general population. Or even if they are a factor in spread. Scandalous, really.
We also don't know (I believe) if vaccination would reduce infection, rather than just severity of illness/immunity to illness. That, obviously, makes a difference to the priority of vaccination.
But as for not caring about the adults in school - I just don't think that's true.
