Where spike is involved LongCOVID will be a significant possibility for vulnerable individuals
. Symptoms from newer variants might be less severe in acute stage, but LongCOVID is know not to reflect acute severity.

I have asked my @WHN collaborators their thoughts. This is an interesting indeed!

1/ Fantastic new preprint from
@resiapretorius.bsky.social @CallumThomas96 @DrMark_Faghy and co. This new study suggests that even light exercise may worsen #LongCOVID. by breaking up #microclots and triggering inflammation.

These findings suggest that PV/PIS is characterized by persistent immune dysregulation and coagulopathy, with proteomic signatures only partially overlapping those previously reported in prior proteomics analysis on Long COVID samples collected prior to vaccination availability. Our results highlight the complex interplay between immune activation, endothelial dysfunction, and coagulation pathologies in PV/PIS, while also highlighting distinct differences between these systems in Long COVID and PV/PIS, paving the way for more targeted protein research in these conditions.
