This charming Man My six year ended up in the hospital with covid and there was a lot of other children in there with him. Please shut the fuck about how harmless pediatric cases are. You don't work in the hospital, you don't conduct clinic trials, like shut the fuck up.
Actually I was an Intensive care nurse for twenty years. I don't work in ITU now but I'm in touch with many nurses and I have friends with 'vulnerable' kids, too. I also worked in pediatric ICU at St. Mary's, London and Kings College and a school for kids with Special Needs. Even kids with epilepsy contracted it and were fine, though the few cases in the UK admitted to ITU were kids with epilepsy or had rare genetic conditions.
I'm not doubting your sincerity, but the vast, vast majority of kids barely know they have it. Certainly the hundreds of kids I know, including mine, were fine. I would say most of those kids in hospital with your son, were there for other conditions and also happened to test positive to COVID.
