Error Bars on Kid Death in 2021 show Significance
But did not show significance in 2020 under COVID
The healthiest age group is from age 5 to 14.
During 2020 under COVID, the yearly death rate did not change significantly. But when the COVID jabs rolled out in 2021, the yearly death rate increased significantly. This means that the 95% confidence intervals around the death rates no longer crossed over each other (no longer overlapped):

Technical: To get the 95% confidence interval (the error bars in the chart), the CDC’s method of using the inverse Gamma function was applied to the raw number of deaths each year. This method appears at the bottom of the first report listed below, NVSR 70, and is under the heading of “Confidence intervals and statistical tests based on 100 deaths or more”
