I've heard this a few times from different teaching colleagues that by keeping schools open it is allowing herd immunity to 'work it's magic'. In theory and from what we know majority of children will only get a mild form of the disease. If we also take the idea that most parents of school age children are under 50 then granted they have no underlying health problems then it won't affect them as badly either.
Just for disclosure I'm fully against this but it's something that has been playing on my mind. Do you feel there is any truth behind this?
