Created in 2007, the I-REIVAC network (Innovative Clinical REsearch Network in VACcinology) was certified an F-CRIN Network of Excellence in 2014.

The network's scope focuses on the evaluation of vaccines and the use of monoclonal antibodies for preventive purposes in healthy volunteers and "specific populations" (immunocompromised individuals, the elderly, pregnant women, patients with comorbidities, etc.) in the field of infectious diseases.

Coordinated by Professor Odile Launay, an infectious disease specialist and vaccinology researcher at the Cochin Hospital in Paris, and Professor Eric Tartour, an immunologist at the HEGP Hospital in Paris, the network conducts clinical research projects: clinical trials (phases 1 to 3), real-life studies (phase 4), large-scale epidemiological studies (cohorts, cross-sectional studies, etc.) and also develops a social science approach, including on the acceptability of vaccination programs.
