The PALE-Blu project brings together leading laboratories in Europe with established track records working on the epidemiology, modelling, vaccinology, diagnostic systems, vector biology, pathogenesis, transmission and control of Bluetongue virus (BTV) outbreaks, together with established institutes in several other countries that represent a potential ‘source’ of the BTV strains that continue to invade Europe. PALE-Blu is an EU Horizon 2020 funded project formed of 19 partners over 15 countries and runs from 2017 – 2020.
