In the UK we're not vaccinating under 18s in volume - not yet anyway. I really don't want my kids to take part in the Great Adolescent Long Covid Experiment.
Hopefully! Although I think "no clear evidence yet" isn't the same as "no problem". From the article itself there is a lack of clarity/conclusiveness:
"Children can experience SARS-CoV-2 postviral syndromes, but it is unclear to what extent these individuals are affected by long COVID"
We've been learning new stuff about COVID for 18 months now. I suspect we'll continue learning more about it for a long time to come. And I'm not keen to bet my kids' wellbeing on "it'll be fine" if I can avoid it (and they may yet catch it anyway - one can't wrap them in cotton wool).
Just saying - I prefer caution over complacency really.
