obviously every parent will need to decide what makes most sense for their kid with help from their pediatrician and other experts. From what I have read, it seems that many think that when covid becomes endemic, young kids will end up being exposed to it numerous times by the time they turn 5-10. Then, when the kid is exposed to covid again at older ages, they will have built up enough immunity to not have a severe effect from covid. For young kids, every new illness they get is novel to them, so their immune systems have been better able to deal with covid, but for us older people, our immune systems aren't as good at dealing with novel viruses so it's been a little unpredictable to know how severe we will end up getting covid.
Anyway, I have a daughter who is halfway between 10-11, so I feel like she's old enough where getting the vaccine would be a good idea, because I think there is the possibility that with cases going down, there is a chance that she won't be exposed to covid until perhaps later on, and the older she gets, the higher her risk becomes. So I don't fear the idea of her getting exposed to covid now with the lower pediatric dose so that when she is exposed again when she's older, her immune system will better know what to do. It also helps that she is a girl and the myocarditis risk has not been seen in girls so far.
