Yes, I’ve heard of long covid. But it might as well be named “mid term COVID” as it applies typically applies to anyone who continues to see symptoms past the 3-8 month mark (this varies from study to study).
The vaccine doesn’t prevent this either though, but does seem reduce the likelihood, slightly.
We still don’t know what’s going to happen in the next 5+ years to come (with covid or the vax). These things can take a while to manifest sometimes, which is partly why vaccine testing is usually so extensively long, like 5-10 years (just not in this case for some reason).
