evidence: Study reveals lower cardiovascular risks after COVID-19 vaccination, despite increased myocarditis and pericarditis in younger males. [...] Existing evidence does not indicate that COVID-19 vaccination increases the risk of MI, whereas the risk of atrial fibrillation (AF) is extremely low. Furthermore, individual-level data has not suggested an increased risk of stroke after vaccination. [...] The current study reports reduced risks of several serious cardiovascular outcomes following COVID-19 vaccination in a cohort of Swedish individuals, which could be attributed to protection conferred by the vaccine against severe disease. Nevertheless, an increased risk of extrasystoles, TIA, myocarditis, and pericarditis was observed after COVID-19 mRNA vaccination.
