Do COVID Vaccines Stave Off New Medical Conditions? Large study finds breakthrough cases linked with lower risk of diabetes, hypertension diagnoses Molly Walker medpagetoday

Risks of long COVID symptoms and the incidence of new onset hypertension, diabetes, and heart disease were lower among vaccinated patients with breakthrough infection versus those with COVID who were unvaccinated, a large analysis of medical records in the U.S. suggested.

Compared to those who were unvaccinated, relative risks were 0.33 for hypertension (95% CI 0.26-0.42), 0.28 for diabetes (95% CI 0.20-0.38), and 0.35 for heart disease (95% CI 0.29-0.44) at 90 days following COVID diagnosis for the vaccinated group, reported Grace McComsey, MD, of Case Western Reserve University in Cleveland, Ohio, and colleagues.

Moreover, risk of death 90 days later was significantly lower as well (RR 0.21, 95% CI 0.16-0.27), the authors wrote in Open Forum Infectious Diseases.  ...
