TRANSVAC is a collaborative infrastructure project funded by the European Commission (EC), initially under the 7th Framework Programme (FP7) and then under Horizon 2020.  The project is a joint effort of leading European groups working in the field of vaccine development, and is coordinated by the European Vaccine Initiative (EVI). TRANSVAC is designed to accelerate vaccine development by enhancing European vaccine research and training, and increase sustainability of EC vaccine projects by implementing a permanent research infrastructure for early vaccine development.
