Abstract

The findings of this cohort study suggest that among highly boosted patients with cancer, the overall risk of postacute sequelae following Omicron SARS-CoV-2 infection was not significantly elevated compared with noninfected patients; however, patients who were hospitalized for COVID-19 remained at increased risk of postacute sequelae despite administration of COVID-19 therapeutics. These findings further suggest that COVID-19 vaccination and boosting remain important in mitigating the risk of long COVID among immunocompromised patients during endemicity.
