This virus is like measles and polio: a virus with long-term impact.
Even a “mild” case in a vaccinated individual can lead to long-term issues which cause a measurable uptick in all-cause mortality in the first 6 months, and get progressively worse with time.

For parents looking to protect their children with quality masks, my family used @masknerd's detailed analysis to select one that fits our daughter. She loves it - and it's so comfortable she doesn't mind grabbing it even for outdoor play.

Update: in reviewing this thread, @dgurdasani1 pointed out an important nuance I'd failed to mention.
The Oxford University paper's primary analysis counted a single dose as "vaccinated," which doesn't match our colloquial usage of the word to mean fully vaccinated.

The paper's sub-analysis, however, showed protection against several persistent symptoms with 2-dose vaccination, even though the primary analysis didn't.
That's very good news!

That corroborates the findings from the Université de Paris study which Professor Iwasaki ( @VirusesImmunity) described in this thread.
The graph of complete remission in her second tweet is of particular interest to anyone battling Long Covid.

Anybody currently exposed or worried about their personal risk of Long Covid will be happy to read that the study found
"Vaccination reduced the symptoms of long COVID and doubled the remission rate of long COVID symptoms at 120 days."

Let's review: vaccines do offer benefits against Long Covid, with a 2-dose sequence increasing the chances of full remission, and providing protection against a number of pernicious sequelae.

I have deleted post 41 of the thread, so that it can no longer be used for anti-vaccine propaganda, with thanks to @kallmemeg for drawing my attention to the way it was being misused.
Posts 40-42 and 72-73 reference this study:
