death rates, as the attached link explains...personally, I wish the article talked more about kids being 'spreaders' as well...that's an important aspect of combating a pandemic, too.
I'll also reference our own family ID Specialist here, who has three kids in the 5-11 yr age group...they have been vaccinated and will be boosted when necessary due to the exceptionally transmissible Omicron variant.
As the link I posted earlier from Johns Hopkins states...vaccines for kids are highly effective...and safe...please trust the CDC...they have a LONG history of doing the right thing to keep people healthy, and that includes Polio, MMR, etc...they haven't changed their 'stripes' all of a sudden.
