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 a distinguished investigator whose research focuses on the evaluation of vaccine safety and effectiveness and on the surveillance of vaccine-preventable or other infectious diseases. Dr. Naleway is an investigator with the CDC-funded Vaccine Safety Datalink, a national project that links electronic medical records data from several integrated health care delivery organizations to monitor vaccine safety. Additionally, 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 personnel, and the early effects 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 and completed a postdoctoral fellowship in epidemiology at the Marshfield Clinic Research Foundation. She has an adjunct faculty appointment with The University of Iowa College of Public Health’s Department of Epidemiology. She joined CHR in 2003.

Selected Current Studies

  • Vaccine Safety Datalink-Infrastructure Activities (CDC)
  • Multi-Country Investigation of Vaccine Effectiveness Against Hospitalized Influenza in Pregnant Women (CDC)
  • Prevention of Injection Site Pain and Syncope Associated with Preteen and Teen Vaccination—PAVE (NVPO)
  • Epidemiology of Novel Influenza Virus Infection and Evaluation of Antiviral and Vaccine Effectiveness “Flu Pandemic” (CDC)
