// Sqad, is "long covid" different from standard Post Viral syndrome? // well since you asked one is a subset of the other
take lots of people wiv Long Covid ( as in I had covid and I feel awful still after x months)
some will test positive some negative
some can be post viral - but they shouldnt be positive ( not post- geddit)
and so on
and you can follow them up....
and you get an article like this

which says "if you wait a long enough time - alot will get better" and then you read the next article
and puzzled 54 - there is nothing on long covid and the vaccine as one wasnt really designed to cure/prevent the other - see above
