5,000 participants. Five recruiting centers. Two months. One shared goal.
At the height of the COVID-19 pandemic, SDD supported an international vaccine clinical trial under exceptionally challenging conditions.
🌍 International logistics restrictions
🧪 Complex biological sample shipments
💉 Competition with a national vaccination campaign
👥 A rapidly shrinking pool of eligible participants
Our team activated 12 clinical centers, and five of them successfully recruited all 5,000 participants within the required timeline.
Daily collaboration with investigators, intensive site support, rapid laboratory operations, and effective logistics management helped us keep the study on track.
The vaccine was subsequently registered in China.
When every day counts, experience and teamwork make the difference.
