I’m really pleased to hear this. Covid doesn’t just affect kids with underlying conditions. I have a completely healthy son, no underlying conditions who went through covid, Mis-c and complications for a year. Yes that’s rare, but it shows that you can’t just assume your kids will brush it off and be fine because they’re “healthy”.
Also, the risk of myocarditis is higher after covid than after after the vaccine (something a lot of people seem to have misunderstood). The cases of myocarditis after the vaccine seem to be mild, and clear up in a week or so. My son’s heart issues after covid are still there, over a year after he caught it. Easy choice in my view!
Having said that, if people don’t want to get their kids vaccinated (and their kids are happy with that) that’s fine, but I hope they make that choice fully informed - not after having read whatever nonsense on mumsnet or Facebook. Talk to your Gp if you’re worried. Look at peer reviewed papers, not videos on YouTube.
