Sweden’s Covid-19 expert Anders Tegnell has come under fire for appearing to ask whether a higher death rate in elderly people was a fair price to pay for herd immunity…

‘One point would be to keep schools open to reach herd immunity faster,’ Tegnell said, to which Salminen emailed back that Finnish health agency had considered this but rejected it because ‘over time, the children are still going to spread the infection’ to other age groups.

Finland’s modelling suggested closing schools would reduce the spread of Covid-19 among elderly people by about 10%, Salminen said.

Tegnell responded: ‘10% might be worth it?’
