> the risk is minuscule compared to COVID-19 itself You don't know this at all - we don't know what age groups are affected here, and COVID is pretty much negligible in many younger age groups. It's best to wait for more data to come in before drawing any conclusions.
> COVID is pretty much negligible in many younger age groups "Paediatricians in Israel, which has surged ahead in vaccinating its adult population, reported a sharp rise in covid-19 infections among young people, with more than 50 000 children and teens testing positive in January—more than Israel saw in any month during the first and second waves." https://www.bmj.com/content/372/bmj.n383
A single metric (e.g. positive tests) is not enough to assess any severity here, and even those metrics come with caveats because all of our methods of determining them are imprecise.
