Blood-Related Syndrome Is Being Seen After Developing COVID-19 or Vaccination

(ContagionLive) In a study that was published in Nature Cardiovascular Research yesterday, investigators point out the increased incidence rates in POTS for people who are vaccinated or who have had COVID-19. “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,” the investigators wrote. They also said that people who had COVID-19 were reported to have POTS at a rate 5 times higher than the incidence rates of POTS after COVID-19 vaccination.
