Vanden Bossche is an expert in the space with an extensive resume. He received his DVM from the University of Ghent, Belgium, and his PhD degree in Virology from the University of Hohenheim, Germany. He has worked for several vaccine companies (GSK Biologicals, Novartis Vaccines, Solvay Biologicals) to serve various roles in vaccine R&D as well as in late vaccine development.
I have far more respect for a veterinarian than one of the specialist physicians with an MD. If you ask a cosmetic surgeon to give advice on a virus and he or she is completely clueless. If you ask a DVM he or she will be able to give you the entire rundown of dangers and treatments. An MD only needs to study one species. A DVM must know them all.
