The nominating institution CISPA on the breakthrough:

The mission: Build a Corona Warn App that warns users if they have been near an infected person. How to do this while protecting anonymity? Based on our work with DP-3T, the privacy-preserving exposure tracing protocol that makes the scientific foundation for the German Corona Warn app, we ensured the app implements it securely. The app protects millions of citizens, and is one of the largest privacy-by-design systems ever deployed, and will soon even enable exposure notification across borders.
