Your original statement was "that COVID was not a threat to kids". That is what I took issue with and your are demonstrably wrong.
Your next criticism was that I did not provide a link. Now you are saying I didn't address pneumonia. Here is part of an abstract
"We find that in one state alone—Hawaii—three years of Covid-19 mortality is equivalent to influenza and pneumonia mortality in the three years preceding the Covid-19 pandemic. For all other states, at least nine years of flu and pneumonia are needed to match Covid-19; for the United States as a whole, seventeen years are needed; and for four states, more than 21 years (the maximum observable) are needed. These results provide an easy-to-understand calibration of flu as a heuristic for Covid-19, and vice versa."

Covid is far more contagious than the flu.
The last Flu pandemic to rival the latest Covid Pandemic was back in 1918. We didn't even know what viruses were back then and letting nature take its course was the only solution.
