Summary

This study followed over 1,100 adults in the Netherlands who received monoclonal antibodies or antiviral pills for COVID-19. Researchers collected blood samples and nasal swabs over 90 days to measure how the virus and the body's immune response changed during treatment. The goal was to understand which patients benefit most and to watch for new viral variants or side effects. Participants did not receive any experimental treatment, but the findings may help doctors use these drugs more effectively in the future.
