In case you have not figured it out yet, i both have access and know my way around academic research:
The paper was retracted for a number of reasons including questionable ethics of the submitter, and it is apparently full of errors, even at the most basic, i.e. the name of the test.
Comment made by someone,
I graphed the data from the abstract, it doesn’t support the claims, basically, the inflammatory markers are not elevated. The error bars are very wide and overlap substantially between pre- and post- vax measures, which means there is no meaningful difference between the figures. There is a large range of other issues with the data, but principally they are using an algorithm that is meant to weigh long-term risk factors against the risk of cardiac events, not transient changes associated with infection or vaccination as well as using an algorithm meant for individual risk to estimate group risk without reporting confidence intervals.
