Summary
This study followed nearly 2,000 healthy employees from two research institutes to see how their bodies produced antibodies against the COVID-19 virus over time. Participants gave blood samples at the start and then again at several points over a year. The goal was to learn about the immune response in people without active infection, not to test a treatment.
