I’m honestly for it and I don’t think it’s that big of a deal. Most kids will still follow what their parents say, and the difference would probably be only seen in cases where the parents are anti-vaccine and the child feels that they know better or wants the vaccine for x or y reasons - which again, is probably fine assuming the risks are low and the child understands what they are. I really don’t think parents should be able to their kids just because they hold certain beliefs
If the kid chooses to agree with their parents/agrees with them then at least they have some sort of choice there
I recently found out that some of my extended relatives have refused to vaccinate their child (I think they’re a newborn or a toddler) at all. I honestly hope that their child is given the opportunity to get vaccines by an age where they understand their situation and may feel different to their parents without needing parental consent, hopefully before they’re 16 or 18. Obviously covid may not be as dangerous as other viruses but eh
