Postural orthostatic tachycardia syndrome (POTS) was previously described after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection; however, limited data are available on the relation of POTS with Coronavirus Disease 2019 (COVID-19) vaccination. Here we show, in a cohort of 284,592 COVID-19-vaccinated individuals, using a sequence–symmetry analysis, that the odds of POTS are higher 90 days after vaccine exposure than 90 days before exposure; we also show that the odds for POTS are higher than referent conventional primary care diagnoses but lower than the odds of new POTS diagnosis after SARS-CoV-2 infection. Our results identify a possible association between COVID-19 vaccination and incidence of POTS. Notwithstanding the probable low incidence of POTS after COVID-19 vaccination, particularly when compared to SARS-Cov-2 post-infection odds, our results suggest that further studies are needed to investigate the incidence and etiology of POTS occurring after COVID-19 vaccination.
Through analysis of the electronic medical records of 284,592 vaccinated patients, using a sequence–symmetry analysis, Kwan et al. show that the risk of postural orthostatic tachycardia syndrome (POTS) is increased after COVID-19 vaccination compared to a 90-day control period before exposure—although 5.35 times lower than the risk of POTS occurrence after SARS-CoV-2 infection.
