Training scientists in vaccine research and development is crucial in order to sustain Europe’s excellence in this field. The TRANSVAC2 Consortium has set up training modules at leading European centres (in collaboration with WP18 partners) that can be combined to create customised international courses on vaccine R&D. Two rounds of customised training courses are planned. Participants can select topics as needed in their field of vaccine development, and the timelines of the various modules will be harmonised in a way that allows a logical continuation from one topic to the other.
