Did you know that protection against COVID-19 weakens over time?  Researchers in the Quantitative Viral Dynamics group have contributed to the development of the COVID-19 Immunity Estimator to help communicate this knowledge to the public.

The COVID-19 Immunity Estimator is designed to provide personalized estimates of protection against infection, and against severe disease based on an individual’s previous history of COVID-19 infection and vaccination. Originally released in August 2023, the COVID-19 Immunity Estimator is available in both English and Spanish language versions.
