1. Vaccines avoid much risk but not all long term effects. Get vaccinated.
2. Contrary to what she says, the thread does have a newer study in it.
3. Of course the studies are old. Cannot get data on Long COVID without time.
4. Warning of risk is not "inducing fear".
You will have to take care of yourself, that much is clear. Good luck.
Also I should point out the ridiculousness of the fear assertion.
If the original author wanted to stoke fear I doubt writing a rational 40-50 post thread with references to studies and their conclusions is really going to be the best way to do so.
I got a few questions on that thread about particles floating. Here's a quick explainer although of course there are plenty of air experts on here as well, so I will try to do a with a lot of pictures to be different.
Historically, humanity has had two major theories of disease spread: miasma (arises in swamps and floats in air) and contagionism (disease spread by contact between people).
In the 1800s we learned about germs, and that they live in us, and that we spread them.
