It's not a vaccine.
Kids aren't succeptible to covid.
Covid probably isn't real, pic related.
Worst case for very old people who died from covid, it was the same as a flu. Could it have been influenza? Yes it could have been, because their test couldn't tell the difference and most people weren't given genetic tests which would be needed to tell for sure if they had it.
