Risk of Reinfection and Incidence of Chronic Symptoms After SARS-CoV-2 Infections
This study showed that a severe acute respiratory syndrome coronavirus 2 infection reduced the risk of reinfection among vaccinated individuals by 0.50 (95% CI, 0.39-0.64) over a 1-year period, after accounting for unreported infections using avidity-based serology. Reciprocally, chronic symptoms increased from a baseline of 21% (95% CI, 16%-28%) among infection-naïve individuals to 43% (95% CI, 30%-61%) in reinfected individuals.
