Phase 1 trials were carried out in 2015/ 2016 by the EBOVAC1 project. These trials gathered preliminary information on the safety and tolerability of the vaccine regimen. The immune response generated by the regimen will also be evaluated longer term.

The ongoing Phase 2,  Phase 2B EBOVAC-Salone,and PREVAC Sierra Leone trials are being carried out in parallel by the EBOVAC2 and EBOVAC1 projects respectively to speed up the clinical development of the vaccine regimen. In these trials, larger groups of people are receiving the vaccine regimen, allowing the projects to gather further information on the regimen’s safety and immunogenicity, including in specific groups such as children and the elderly.
