What we can confirm
Multiple recent observational studies and meta-analyses report an association between influenza vaccination and a lower risk of atrial fibrillation (AFib), and professional summaries describe a new cohort study showing about a 20% lower AFib risk in vaccinated people, so the claim that a new study found flu shots are linked to reduced AFib risk is accurate, though causality is not yet proven and randomized trials are still needed.[1][2][3][4][5][8]
