Vaccines and infectious diseases
Meridian is a leader in high-volume vaccine trials and research programs that require hard-to-reach patients.
The majority of the world’s leading Sponsors and CROs have made Meridian a strategic partner for their infectious disease research programs. Meridian provides a broad national footprint to support rapid enrollment, even for studies involving sensitive cohorts (e.g., seniors, children, at-risk populations).
Several of Meridian’s principal investigators are also sought after by Sponsors and CROs to guide vaccine-related protocol development. These investigators have had research published in prestigious industry journals, including Vaccine.
