Host Defense Fellowship

Host Defense Fellowship

Nationwide Children’s Hospital’s GME-approved, one-year Infectious Disease Host Defense Fellowship provides additional training and expertise in the comprehensive management of infections in immunocompromised children.

Fellowship Overview 

The Host Defense Fellowship was developed as part of Nationwide Children’s Hospital’s Pediatric Infectious Diseases Division and Host Defense Program. Established in 2015, we are the first pediatric fellowship program in the United States offering specialized training in infection prevention and management in immunocompromised children.

The one-year fellowship provides formal training to physicians who successfully completed a 3-year, ACGME-accredited pediatric infectious diseases fellowship and possess a strong interest in caring for immunocompromised children.

Through the fellowship, trainees are provided a diverse clinical and research experience at both Nationwide Children’s Hospital and The Ohio State University. Upon program completion, fellows will develop expertise in the infectious disease management of immunocompromised children.
