We will present results of a study of pertussis vaccine effectiveness in Ontario derived from the first study in Ontario to make use of integrated Public Health Information System (iPHIS) data (2006-15) linked to Canadian Institute for Health Information (CIHI) administrative data at the Institute for Clinical Evaluative Sciences (ICES). The findings we will discuss are part of a Canadian Immunization Research Network funded study of pertussis vaccine effectiveness in Canada. This session builds upon previous PHO presentations on a conceptual model of vaccine effectiveness and pertussis epidemiology in Ontario. Our results will illustrate some of the key concepts that underpin vaccine effectiveness research. We will compare and contrast results with a previous test negative study design that was published in 2016. We will discuss characteristics of surveillance case definitions and laboratory reporting that affect vaccine effectiveness estimates particularly through their impact on the sensitivity and specificity of case ascertainment.
