Meet Allison Naleway

Allison Naleway was interested in science from a young age, but it was a coincidental suggestion from a visiting professor that led her to choose a career in epidemiology. Her research portfolio includes studies of the flu vaccine, the HPV vaccine, and vaccination during pregnancy.


Allison Naleway, PhD, is an epidemiologist whose research focuses on the evaluation of vaccine safety and effectiveness and the surveillance of vaccine-preventable and other infectious diseases. Dr. Naleway is the site Principal Investigator for the Vaccine Safety Datalink, a national project funded by the Centers for Disease Control and Prevention (CDC) that links automated medical records data from several integrated health care delivery organizations to monitor vaccine safety. She leads the VSD pregnancy working group.

She has collaborated with the CDC on studies to assess the effectiveness of influenza vaccination during pregnancy, influenza vaccine choice and effectiveness in health care workers, and the early effect of human papillomavirus vaccination on HPV-related outcomes.

Dr. Naleway received her master’s and doctoral degrees in epidemiology from The University of Iowa’s College of Public Health. She completed a postdoctoral fellowship in epidemiology at the Marshfield Clinic Research Foundation. Dr. Naleway has adjunct faculty appointments with Oregon Health & Science University's Department of Public Health and Preventive Medicine as well as The University of Iowa College of Public Health’s Department of Epidemiology.
