Complete nonsense. You’re cherry picking immune compromised and very sick children, and using that as a basis for all children. That’s completely false. A study from 2022 or 2021 studied the same covid. It didn’t all of a sudden get much more severe. Stop the nonsense already.
The article indicates Deaths from 2021.
2021 had the most severe variants of COVID. Lot's of excess death from lower age groups for these variants. Delta being the worst for people not vaccinated. Kids couldn't get vaccinated then.
2022 is a different animal. Omicron is much easier spread but far less pathogenic.
