No results posted yet for this study

Summary

This study looks at how many healthcare workers at CHSD hospital developed antibodies against COVID-19 after the second and third waves of the pandemic and after receiving a vaccine. It aims to better understand who might still be at risk of infection, how long immunity lasts after getting COVID or the vaccine, and how reliable previous antibody tests were. Blood samples will be collected from volunteer hospital staff during a one-month period to measure their antibody levels and compare them to earlier results.
