SeroTracker is a knowledge hub that tracks and synthesizes findings from SARS-CoV-2 serosurveillance efforts worldwide. SeroTracker was initiated in early April to serve the COVID-19 Immunity Task Force’s need for global serological testing data, and is supported by the Task Force. 

As the acute phase of the COVID-19 pandemic passes its peak, many countries are accelerating their investments in serological (antibody) testing. Understanding population antibody patterns and potential immunity is of great interest to clinicians, public health officials, and policymakers alike. 

The SeroTracker Team is a global collaboration with 20 researchers, data scientists, and economists from six universities in the UK, Canada, and the United States. Academic affiliations include: University of Oxford, University of Toronto, Harvard University, University of Waterloo, University of Calgary, and McGill University.
