Six thousand deaths attributed to vaccines so far. How many 12-to-17-year-olds have died from Covid?
Let's pretend that those 6000 deaths reported to the VAERS database have all ben confirmed to have been caused by the several vaccines, even though many have not been confirmed as such.
As of Friday, July 2, 2021 1:35 PM ET, 181,650,678 Americans have received at least one dose of one of the vaccines, and 156,255,896 are fully vaccinated. Using the latter number, that means the death rate for the vaccines is ~ 0.00384% (were the at least one dose number used the rate would be 0.003303%).
This world is imperfect and life is never risk free. By the numbers here,

As to your question, 324 as of June 23, 2021,
https://www.statista.com/statistics/1191568/reported-deaths-from-covid-by-age-us/ . But comparing under-18 Covid deaths to
all deaths that might or might not be caused by Covid vaccines is an apples-oranges comparison. Comparing the two death rates for only youths under 18 would be less invalid.
