Summary

This study followed over 1,100 high-risk COVID-19 patients in the Netherlands who received new antiviral drugs or monoclonal antibodies. Researchers collected blood samples and nasal swabs over 90 days to see how the virus and the body's immune response changed during treatment. The goal was to learn which patients benefit most and to watch for new virus variants, not to test a new treatment directly.
