Long Covid is not a defined term. It comprises everything from "post-hospitalization syndrome" -- which is something that has existed since long before Covid -- to "slight cough for a few weeks". If you're young (under 65) and otherwise healthy, you are highly unlikely to have anything more than a minor illness. Particularly after vaccination.
Here's a paper that might interest you:

> In this cross-sectional analysis of 26,823 adults from the population-based French CONSTANCES cohort during the COVID-19 pandemic, self-reported COVID-19 infection was associated with most persistent physical symptoms, whereas laboratory-confirmed COVID-19 infection was associated only with [loss of smell].
In other words, in a large study out of France, the only "long covid symptom" actually correlated with SARS-CoV2 infection was loss of smell. All of the other various symptoms were associated with self-reported illness, but not confirmed illness.
This is a fairly strong argument that "long covid" is at least partly psychosomatic. We'd probably see this more clearly if the various "long covid" studies didn't rely exclusively on self-reporting of symptoms, and mix together all levels of illness.
To combat this, perhaps we could swap the masks out with gags. /s
Long COVID is a big deal, and it apparently affects half of those who get COVID [1]. Furthermore, even double-vaxxed, while protected against hospitalization or death, are still at risk (reduced about 50%) for long COVID [2].
Until/unless Omicron has been proven to have less severe long covid symptoms, yeah I'm treating it with the same caution that I'd do with Delta.
