I don't really want to interject, but...
Covid used to be 'adult affected only'.
Covid 'used to be only minor in kids'.
Covid used to be 'less transmissible in young people'.
Covid used to be 'comorbidity related'.
Covid used to be 'solved with a vaccine, no two vaccines... and a booster at least, with no side affects and rare breakthrough cases'. Oh and said vaccines only having a short shelf life and not as strong as your own internal immune system which is weakened when taking a vaccine... Apparently.
And now, you're reacting to "Long covid has been proven to not be a thing in kids" how...?
How much time is needed to study a new borne pandemic with no study data? One would need the right amount of time and the right amount of patients to study, no?
Nobody has 'proven' anything, at any point, right now.
Even as people fight over it, it's becoming clear it's moving from pandemic to endemic and we'll just have to treat it like other viruses like the common cold or flu, which any ol' people can die from with complications within their systems.
