IDK, but there seems to be an effort by some of the left, since they can't get to the parents, to go straight to indoctrinating children on a number of issues. There was the school in California that was bribing children with ice cream to get the vax, as well as, telling kids not to tell their parents. Although, in most cases, kids are not getting vaccinated without the parents knowledge.
I saw a TV ad last week that was specifically aimed at getting children vaccinated. Fortunately, parents understand the risks and rewards. That's why very few children have been boosted and only 17% of the entire population.
Yes, any mandating of Covid vaccines is unethical.
