Some Japanese researchers did the most simple thing: compare -via PET scan - heart inflammation in apparently healthy #vaxxed and #unvaxxed people. Healthy means no external signs of #myocarditis.
Results: main myocardial inflammation index was 3.3 in unvaxxed and 4.8 in vaxxed people. Roughly a 50% increase.
Here is the study. DYOR of course but no one ever compares vaxxed and unvaxxed, at any level, so this is huge.
