We lead the surveillance and evaluation of adverse events following immunization (AEFIs) in Ontario and provide resources and support for immunization stakeholders to understand and communicate about vaccine safety.
Applied Immunization Research and Evaluation
Our immunization research and evaluation delivers innovative, interdisciplinary, responsive and impactful evidence to help guide and strengthen immunization programs. We also conduct training and education to build capacity.
