Vaccines & Immunology

DiagnoSearch has built proven expertise in infectious disease and vaccine clinical trials. For nearly three decades, we have partnered with global biopharmaceutical and public health organizations to advance vaccine development programs that address critical health challenges. Our experience spans from early clinical phases to large-scale global studies.

We understand the unique complexities of vaccine trials from site readiness and specialized laboratory support to handling high-volume data with speed and precision. Our integrated  teams in Clinical Operations, Clinical Data Management, Interactive Web Response System, Scientific Writing, Biostatistics, Medical Monitoring, Consulting, Quality Assurance, Pharmacovigilance and Central Laboratory services work seamlessly to deliver high-quality outcomes within accelerated timelines.

Among our early milestone projects were the Meningitis Vaccine Project and MMR vaccine trials in the early 2000s. These laid the foundation for DiagnoSearch’s continued role in advancing vaccine development globally. Since then, we have supported 97+ vaccine trials across 29 countries, enrolling 450,000+ participants.
