Solid Organ Transplantation

Fillmore has investigated the vulnerability of patients receiving chronic immunosuppressive therapy to severe COVID-19, finding that recipients of solid organ transplants face a higher risk of severe outcomes following vaccination compared to patients with other autoimmune conditions. This research highlights the critical role of age and comorbidities in driving disease severity. His work further emphasizes that the timely administration of oral antiviral treatments is essential to reducing the risk of progression to severe disease in this high-risk population.
