Phase 4 Vaccine Trial Participation Case Study

This case study outlines the execution of a Phase 4 vaccine clinical trial by Velocity, focusing on the enrollment of participants. The trial aimed to recruit a total of 1,000 participants across 24 designated sites, specifically targeting generally healthy adolescents and young adults with a particular vaccine status. Enrollment began in October 2024 and concluded in November 2024. Velocity successfully achieved its goal by enrolling all 1,000 participants, including 450 adolescents. Although no formal demographic targets were set for the trial, the company aimed to reflect U.S. demographics in its participant pool. As a result, over 45% of the enrolled participants identified as people of color, which exceeds the U.S. average of 40%. The case study emphasizes the successful recruitment strategy employed by Velocity in the context of this public health initiative.
