The vaccine makes transmission less likely. No-on wants Covid going round and round groups of unvaccinated children, who are then in contact with older people at home. It's not just about the person being vaccinated, it's also about everyone else - as is always the case with public health issues.There is alot of talk about vaccines in children.
So if the vaccine doesnt stop transmission and Corona isnt really dangerous to kids why would they need to get vaccinated?
My great-nephew had Covid recently, he's 12. Although he wasn't very ill, he's still struggling with fatigue weeks later. His parents are very pro-vaccine, but he was just too young to get one before he caught Covid at school.
