Kristen A. Feemster, MD, MPH, MSPHR, is Director of Research for the Vaccine Education Center at Children’s Hospital of Philadelphia.
Areas of Expertise:
Epidemiology of vaccine preventable diseases with a focus on community and social factors, Global and domestic vaccine policy, Vaccine hesitancy, Ambulatory healthcare associated respiratory infection and surveillance Locations:Main Hospital Appointments and Referrals: 1-800-TRY-CHOP(1-800-879-2467)
Dr. Feemster’s portfolio reflects a longstanding interest in public health and a commitment to improve outcomes for children by addressing contextual factors that may impact disease risk and access to health services. This has resulted in two complimentary foci: 1) understanding how environmental factors, social networks, and community systems affect the epidemiology of infectious diseases; and 2) evaluating policies related to the prevention of pediatric infectious diseases, specifically vaccine policies. Her current research includes vaccine acceptance among parents and immunization providers in the U.S. and internationally, community-based interventions to improve vaccine uptake, neighborhood factors associated with the incidence of pertussis and influenza, and healthcare associated respiratory infection in the pediatric ambulatory setting. This body of work has also demonstrated the importance of understanding the drivers of health-related behaviors and adoption of new recommendations to ensure effective policy implementation.
At Penn and CHOP, Dr. Feemster is affiliated with the Leonard Davis Institute of Health Economics, PolicyLab, the Center for Pediatric Clinical Effectiveness and Global Health programs at CHOP. She serves as a technical advisor for an American Academy of Pediatrics global immunization advocacy initiative, and is past-chair of the Advisory Commission for Childhood Vaccines that advises the National Vaccine Injury Compensation Program. In the community, she serves on the boards of the Philadelphia and Pennsylvania Immunization Coalitions.
Dr. Feemster received her MD and an MPH in Population and Family Health from Columbia University Schools of Medicine and Public Health in New York City. She completed pediatric residency at CHOP then pursued a dual fellowship training program in health services research and pediatric infectious diseases; she was a fellow in the Robert Wood Johnson Foundation (RWJF) Clinical Scholars Program at Penn, completing a Master of Science degree in Health Policy Research then returned to CHOP for pediatric infectious diseases training. She joined the faculty in 2010.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
