For starters, what percentage of kids died from covid and what percentage of kids died from vaccines so far? As far as I know the second number is 0.
You're comparing numbers so close to zero that it doesn't really matter. If a child has a greater chance of dying in a car crash while driving to the vaccination center than of dying by the vaccine--or COVID--then the ratio between the latter two hardly matters, does it?
It's also not lost on me that you chose 0.1% for ICU admissions for kids but somehow "forgot" the more comparable 1.2% number for kids that requires hospitalizations due to covid. As for vaccines, as you pointed out, serious adverse events has not shown causal relationship to vaccine itself. I am sure it's more than 0 for these but we can't attribute all of them at all.
Two of my elderly friends were hospitalized for COVID. Neither was in any distress, but doctors wanted to monitor them because of their age and other factors. One was discharged after a day, the other after a few days, without incident, but both count as "COVID hospitalizations". I don't believe it appropriate to put this kind of abundance of caution into the same class as "serious adverse events". When somebody goes into the ICU,
then it's serious.
The other difference relates not just to effect on kids but also kids spreading covid to their families / friends thus making virus circulate a lot more (let alone mutate). We want to stop community transmission - having kids spread them around through schools will significantly obstruct our progress in that regard.
This argument hinges on the claim that the vaccine meaningfully reduces transmission rates, which was evidently true for the original strain of COVID but not the case with the delta or lambda variants. Furthermore, it's not relevant to your "Over 1,000 times safer. Easily." claim.
Finally, it's yet to know what long term effects covid might have or vaccines but at least with vaccines we know they were not designed to have long term issues while covid... well, who knows - chances are you are safer with vaccine than covid in terms of years-away impact.
The long-term impacts of both COVID and COVID vaccines are known unknowns. You cannot quantify risks with unknowns. You can speculate, hope, and prognosticate, but you cannot
quantify.
"Over 1,000 times safer. Easily." is a quantitative statement. I sincerely
hope there are no long-term effects ultimately linked to the vaccines, and I dare even
hope it's likely there will be no long-term effects, but vaccines normally go through rigorous testing for many years precisely because we do not
know this.
The risk is magnified by the fact that the percentage of kids getting stuck for COVID is a large multiple of the kids who will actually contract COVID. If this factor is 8, say, then the vaccine has to be at least 8 times as safe as a COVID infection just to break even. That includes both short and long-term consequences.
