She is a Canada Research Chair (Tier 2) in Applied Pediatric Immunization. Her clinical background is in pediatric nursing, with research training in nursing, public health, and epidemiology.
Dr. MacDonald is the principal investigator leading the Applied Immunization (Aimm) research team. Her research program focuses on identifying and addressing system-level barriers and supports to achieving high vaccine uptake in underserved populations of children and youth. Dr. MacDonald’s research strengths are in quantitative survey methods, epidemiology, and working with administrative health data, but her team uses multi-method research approaches. She prioritizes collaboration with vaccine policy advisors, program administrators, clinicians, and communities to address real-world immunization practice and policy issues.
Dr. MacDonald aspires to increase capacity in immunization research among researchers of diverse identities; as such, she has worked to develop opportunities for trainees who represent communities typically under-represented in academia. Her trainees are engaged in exciting research among populations such as Métis and immigrant youth, as well as youth who are underserved by school immunization programs in Canada and Ghana.

Laura Ekekhor
Research Assistant
Laura is a 3rd year BSc student in the Immunology and Infections Specialization program and is currently working on a variety of tasks, including transcript cleaning for interviews of those who work in public health or medical sciences. The project focuses on the COVID-19 childhood vaccination catch-up program in school programs across the Edmonton and South zone areas.
Laura joined the team out of curiosity for the practical applications of immunization practices in the public health sector. After spending some time with Aimm, I hope to pursue a profession in this field and dedicate my time towards learning more about vaccination coverage and uptake.

Eunah Cha, BSc, RN
Research Assistant
Eunah is interested in vaccination research with particular attention to equity and intersectionality. Dr. Shannon MacDonald supervised Eunah when she was a nursing student pursuing her Honours Project: a scoping review looking at the inclusion (or lack thereof) of intersectionality in Canadian vaccine research. Since then, Eunah has been a Research Assistant on Shannon’s team, working primarily on the COVImm project in data collection and analysis. Outside of research, Eunah works as a Registered Nurse in the Cardiovascular Intensive Care Unit. She loves experiencing both research and bedside nursing and is excited to see how the two merge in her future career!
