About

Dr. Karina Top is a pediatric infectious disease physician and clinician-scientist in vaccine research. She joined the Department of Pediatrics, University of Alberta as a Professor in July 2023. Originally from Nova Scotia, Dr. Top completed medical school and pediatric residency at Dalhousie University in Halifax, NS and went on to complete fellowship training in pediatric infectious diseases and a Master of Science (Epidemiology) at Columbia University in New York. She returned to Dalhousie University and IWK Health in 2011 as a clinician-scientist and consultant in pediatric infectious diseases where she established a research program in vaccine safety and vaccination of special populations. Dr. Top is the Principal Investigator of the International Network of Special Immunization Services and co-Principal Investigator of the Canadian Immunization Research Network’s Special Immunization Clinic Network.

Research

Dr. Top leads an internationally recognized research program focusing on understanding causes and risk factors for rare adverse events following immunization, and improving vaccination practices for people with adverse events following immunization, those who are immunocompromised, and in pregnancy. She leads national and international research projects employing epidemiological and mixed-methods, as well as studies employing genomics and multi-OMICs approaches to better understand causes underlying rare vaccine adverse events.

Current studies include evaluating COVID-19 vaccine safety and the risk of adverse event recurrence after revaccination, identifying the biological mechanisms underlying COVID-19 vaccine-associated myocarditis, and evaluating safety and immune response to live vaccines among children with solid organ transplants.
