I have always tried to read lots of articles and opinions throughout this pandemic to try before forming any opinions. I remember over the summer reading a lot on here and other places about how we were walking into disaster by reopening schools full time etc and I was unsure. Just looking earlier at the attached graph of excess deaths, I was thinking that whilst there have been problems with education as it has stood this term (absences etc), if you look back at the excess death figures especially compared with March it actually hasn't been terrible when weighed up against the fact that 11 million youngsters in the UK have had a term of education and socialisation. When I am saying "not terrible", I mean from a population level of deaths during a pandemic, not that any of those deaths of individuals weren't in any way awful to loved ones.
I suppose the point I'm trying to make is, had we gone for part time schooling or closed schools, I'm sure a lot of people would have said "imagine how the spread would have been with schools open!" and envisaging something bigger than the March peak. And that did not happen.
Just thinking about this with January in mind. It's all very well to close schools and then say "imagine what would have happened with them open" but really we can never know. But we can know for sure the downsides of 11 million children not receiving an education.
