Center for Predictive
Analysis of Viral Evolution
Human pathogens like influenza and SARS-CoV-2 are fast-evolving viruses. At Previr, we predict likely future evolutionary paths of these systems.

Our analysis uses genetic, epidemiological, and antigenic data from animal models and human cohorts to predict frequencies and characteristics of new variants. How future variants interact with our immune systems is important for vaccine development.

Previr works with the Global Influenza Surveillance and Response System on evolutionary predictions to inform the selection of vaccine updates.
