I know it could be that a lot of kids are asymptomatic. What you are missing is that that means they pass it to their teachers and TAs and to parents and grandparents when they return home.
I’m not missing it. At some point restrictions will be lifted and more people will be at risk of the virus. If children are less contagious - whether because they don’t get it or asymptomatic people transmit a lower viral load - then this will be lower risk than millions more commuting on public transport or going into restaurants. And I trust that the school will be protecting its vulnerable staff effectively, even if it means class sizes and teaching are chaotic for a while.
In fact if they are more likely to be asymptomatic, that makes it more dangerous to all the adults round them as they will not show any signs of illness, but will affect adults they come into regular contact with.
‘If’ - a big if. We simply don’t know this.
Forgive me if I don't want my parents to die because I sent my kids back to school too early.
And this is why the risk assessment will be different for each of us. For me, it is relatively straightforward to keep my children away from close contact with vulnerable groups, unfortunately including their grandparents - they don’t live with us. We are resigned to not seeing them for a long time. For you this is clearly different, so your risk assessment will be different.
Can you share that modelling on the ‘super spreader’ vaccination modelling? Does it include vaccinating children if you see them as such a risk?
I’m also curious why you trust WHO more than eg UCL and others, or even PHE who have access to much more data on the UK population.
