After matching, there were no differences (P\u2009&amp;gt;\u2009.05) in demographics or preexisting comorbidities. At 28 days following COVID-19 diagnosis, the incidence of hypertension was 13.52 per 1000, diabetes was 5.98 per 1000, thyroid disease was 3.80 per 1000, heart disease was 15.41 per 1000, and mental disorders was 14.77 per 1000 in the vaccine cohort. At 90 days following COVID-19 diagnosis, the relative risk of hypertension was 0.33 (95% confidence interval [CI], .26\u2013.42), diabetes was 0.28 (95% CI, .20\u2013.38), heart disease was 0.35 (95% CI, .29\u2013.44), and death was 0.21 (95% CI, .16\u2013.27). Differences in both 28- and 90-day risk between the vaccine and no-vaccine cohorts were observed for each outcome, and there was enough evidence (P\u2009&amp;lt;\u2009.05) to suggest that these
