Sorry, my error, I saw the figures for 12 and up in the NYT article you linked to (73%, 62%) and assumed you were vaccinating children, since to me a 12 year old is a child.
Which Covid version is causing damage to your children, because as far as I'm aware (and that's all I'm saying) there have not been any reports over here about any of the versions that we are exposed to, causing an actual risk to children. The reason we appear to be considering the possibility of vaccinating our children is to reduce the chances of them acting as unwitting virus spreaders, and not because the virus is particularly hazardous to them as individuals.
