Humeral Shaft Fractures : Outcomes of Straight Percutaneous Intramedullary Nailing With Dynamic Distal Locking

This study looks at how many healthcare workers at CHSD have developed antibodies against COVID-19 after the second and third waves of the pandemic and following vaccination. By testing blood samples, we want to understand how well healthcare workers are protected, which work areas might be more at risk, and how immunity changes over time after infection or vaccination.
