Abstract

RSV vaccine clinical trials reported higher frequencies of atrial fibrillation in intervention groups compared to control. In this large, population-based, propensity-matched study, we found RSV vaccine was not associated with increased risk of new-onset or recurrent atrial fibrillation within 1-42 days compared to influenza or Tdap vaccines.
