The Urgency of Patient Recruitment in Infectious Disease & Immunology
Infectious disease and immunology studies often operate under intense pressure. From pandemic preparedness to vaccine development and immune therapy trials, every day matters.
- Rapid timelines requiring immediate patient engagement.
- Patient fear or stigma associated with infectious conditions.
- Diversity gaps, especially in pediatric and minority populations.
- Logistical barriers for at-risk or immunocompromised patients.
Delays in enrollment risk undermining public health initiatives and slowing the delivery of critical therapies.
