The chance of vaccine myocarditis scarring and subsequent arrhythmic predisposition is much greater than the chance of Commotio Cordis absent vaccine cardiac injury.  Commotio Cordis is very rare in his age range, non-projectile Commotio Cordis even rarer, vaccine myocardial scarring is very common, the hit on the play was not a major chest blow, and the Buffalo Bills have stated that they are 100% vaccinated.  Had he suffered onset of ventricular arrythmia at the time of chest impact it is unlikely he could have finished a tackle, let alone gotten to his feet after the play.  The most likely diagnosis from the little certainty we have is vaccine-induced myocardial scarring leading to high-adrenaline arrhythmia.  Subclinical vaccine-induced myocarditis must be considered in the differential diagnosis.
