Right, you're are making a big deal out of a kid getting a headache sometime in a month.
And yes -- for an illness that is essentially asymptomatic in children, that's a legitimate concern.
Another way of putting it: this vaccine will make at least as many children as sick as getting Covid itself.
But it was indeed the 7 days following administration, not immediately after.
I guess I don't see a headache or fever from the vaccine as the same kind of sick as Covid, so no need to pursue the conversation if we disagree on that.
