Aim: Vaccines have been mainly described to provide cardioprotective effects with rare reports showing rare association with myopericarditis. However, vaccines have not been well studied regarding its effects on heart rhythm disorders. Methods: we used vaccine adverse event reporting system (VAERS) between 1990-2021 to search for atrial fibrillation and other less prevalent arrhythmia. Disproportionality signal analysis was conducted by measuring reporting odds ratio (ROR) with 95% confidence interval (CI). Results: Over 1,300,000 adverse events were reported between 1990-2021. Among these events, atrial fibrillation was reported 2149 times in association with various vaccines. 90% of atrial fibrillation was associated with COVID-19 vaccines with ROR of 13.18 (CI 95%: 11.3 to 15.4) (P<0.0001). Interestingly, influenza vaccines, polyvalent polysaccharide pneumococcal (PPSV23) vaccine, pneumococcal 13-valent (PCV13) vaccine, zoster vaccine, and tetanus-containing vaccines were significantly associated with reduced atrial fibrillation. Finally, our analysis showed that COVID-19 vaccines were associated with much higher incidence of other cardiac arrhythmias compared with other vaccines. Conclusions: While vaccines have not been linked to heart rhythm disorders, the introduction of COVID-19 vaccines in 2020 showed significant association with atrial fibrillation. This study showed unprecedent detrimental effect of COVID-19 vaccines on atrial fibrillation and warrants the need to take that into consideration when prescribing COVID-19 vaccines.
