INOVIO has deep experience working with coronaviruses and is the only company with a Phase 2a vaccine for a related coronavirus that causes Middle East Respiratory Syndrome (MERS).

Phase I Study

The sponsor completed the first of two doses on 40 healthy participants in April in the Phase I clinical trial testing INO-4800 at the University of Pennsylvania and the Center for Pharmaceutical Research in Kansas City, MO.
