Specialty(s): Infectious Disease, Internal Medicine, Pediatrics Provides direct clinical care to patients at NIH Clinical Center
Major Areas of Research
- Screening healthy volunteers for challenge and vaccine studies
- Influenza and other respiratory virus challenge models
- Transmission of influenza and other respiratory viruses
- Influenza, COVID-19, and other respiratory virus immunity in children and adults
- Norovirus pathogenesis and experimental treatments for chronic norovirus
The LID Clinical Studies Unit (CSU) has validated influenza challenge models that have been used to better understand influenza pathogenesis and to evaluate potential vaccines and therapeutics. In addition, we have several natural history studies to understand short and long-term immunity after influenza challenge and after vaccination. The LID CSU has collaborated with research groups to develop and implement clinical protocols to explore the pathogenesis and evaluation of novel vaccines and therapeutics for other important infectious diseases, including vector borne diseases and diarrheal diseases, such as norovirus.

Alison Han completed her undergraduate degree at Emory University and received a Master of Science degree from Harvard T. H. Chan School of Public Health. She received her M.D. from Morehouse School of Medicine and completed a residency in internal medicine and pediatrics at University Hospitals Case Medical Center/Rainbow Babies and Children’s Hospital in Cleveland, Ohio. She completed infectious diseases fellowship at the National Institutes of Health (NIH) and then joined the LID Clinical Studies Unit first as a fellow and then as a staff clinician.
