Butting in here - just listening to Van Tam, justifying teachers (NOT all school staff) not being vaccinated.
He has compared some mostly male dominated professions, against a comparison with male teachers, to defend their reasoning and that's also been done using data from March to the end of Dec, when schools were shut to all but a few pupils for 2/3rds of that time.
Male teachers make up around 25% of teachers (in 2019, no reason to imagine there's been much of a shift).
I'm not sure that that includes teaching assistants either (who have much higher case rates/mortality?).
Along with that, teachers make up slightly under a half of the total of all school staff.
Can't find any male to female ratio figures for the rest but, outside of facilities (caretaking etc - who generally spend more time outside anyway) my own experience is that the bulk of the rest - admin, cleaning, kitchen staff (of which I am one - and where I note that catering is a pretty high risk profession) are women.
So, they are using figures for the 25% of all male teachers, which ought to be further reduced (to half that? Less?) when you look at all school staff, for a period of time when many of them wouldn't have been onsite anyway for the greater proportion of that time and/or with far fewer kids outside of March - Sep (when SD WAS easy), then setting those against risks to other, more male dominated professions, to produce some fucking made up numbers that will only continue to diminsh the safety of all school staff, along with feeding the idea that it's teachers being difficult, while they experiment with fully opening schools.
