The reporter interviewed Professor Russel Viner, president of Royal College of Pediatrics and Child Health. Apparently, a study was conducted through April to June which collected information of 20,000 students and 100 teachers yet there is no link to this study, did not get peer reviewed or published. It is all just claims at this point. We have no knowledge if these are private schools or public, if there were any safety measures in place, if this included online classes vs in class.

However, according to CDC and the respected studies it cited, there seems to be lower transmission rates among children and transmission from child to family, but this remains inconclusive. There still needs to be more evidence to be gathered.
