The Pirbright Institute and its research partners have granted MSD Animal Health an exclusive commercial licence for a new, effective and affordable vaccine to protect livestock against several serotypes of foot-and-mouth disease virus (FMDV). The new vaccine is more stable than current foot-and-mouth disease (FMD) vaccines and is less reliant on a cold-chain during vaccine distribution – characteristics that give the vaccine greater potential for helping to relieve the burden placed on regions where the disease is endemic in large parts of Africa, the Middle East and Asia. These developments have been possible, thanks to a long-standing collaboration between Diamond Light Source, Pirbright, the University of Oxford, the University of Reading and MSD Animal Health, and the vaccine has been developed over the years from basic science to animal trials. This work has been supported by funding from the Wellcome Trust to speed up commercialisation.
Professor David Stuart, Life Sciences Director at Diamond Light Source and MRC Professor in Structural Biology at the University of Oxford, noted:
We have been working to achieve something close to the holy grail of vaccines. Instead of traditional methods of vaccine development, using infectious virus as its basis, our team synthetically created empty protein shells to imitate the protein coat that forms the strong outer layer of the virus. Diamond’s visualisation capabilities and the expertise of Oxford University in structural analysis and computer simulation, enabled us to visualise in detail something invisible in a normal microscope and to enhance the design, atom by atom, of the empty shells. The key thing is that unlike the traditional FMDV vaccines, there is no chance that the empty shell vaccine could revert to an infectious form. The licence that has just been granted suggests that the work will have a broad and enduring impact on vaccine development.
