I saw that it's mostly severe infection that results in high levels of auto-antibodies. But the studies I saw seemed to indicate that they only focused on acute infection. I wonder what the prevalence of anti-autobodies are in mild cases and how that correlates with the main article's finding of cardiovascular risk increase even in mild cases. Specifically, if these individuals already had auto-antibodies or some other outlying issue, or if this reaction is representative of the entire group.

It could take years for some autoimmune issues to arise. It would be quite concerning if this affects nearly everyone infected, including asymptomatic or mild infections following vaccination.
