East Kilbride mum has accused the authorities of playing “Russian roulette” with vulnerable children’s health. It comes after a number of new cases of COVID-19 at Calderglen High over the September weekend.A letter was sent out last week after a pupil tested positive and the latest cases are understood to be among pupils also.The mum, who doesn’t want to be named to protect her children, has two youngsters at the school with additional health needs who were shielding until school’s went back.But she said the measures in place in schools are not protecting vulnerable children - and that online learning should have been continued for those at high risk.
