Covid-19 Vaccine Effectiveness Study

TARRANT has also partnered with the BC Center for Disease Control, the National Microbiology Lab, and provincial programs from Ontario and Quebec to determine COVID-19 vaccine effectiveness. Patients presenting with symptoms of the disease are recruited by sentinels across the provinces and tested for laboratory confirmed cases. Through a test negative incident case control design, that compares test-positive cases with those testing negative, this data is combined with their vaccination history to determine vaccine effectiveness.
